Solar Nebula Research Paper
Gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass. Gravity of the Earth pulls
objects towards the center of the planet. Gravity or gravitational forces are forces of attraction.
Mass:
Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of
the objects. You exert a gravitational force on the people around you, but that force isn't very strong, since people aren't very massive. When you
look at really large masses, like the Earth and Moon, the gravitational pull becomes very impressive. The gravitational force between the Earth and
the molecules of gas in the atmosphere is strong enough to hold the atmosphere close to our surface. Smaller planets, that have less mass, may not be
able to hold an atmosphere. This can be related to the gravity force lab because you can make the person with either magnet bigger or smaller. When
you made both bigger they were harder to pull apart but when you make them both smaller they were easier to pull apart. Solar Nebula: ... Show more

The cloud contracted under its own gravity and our proto–Sun formed in the hot dense center. The remainder of the cloud formed a swirling disk call
the solar nebula. A solar nebula is a gaseous cloud. The nebular hypothesis has become the theory of the origin of oursolar system. We can relate this to
the vermiculite solar nebula lab. These are related because in the lab it showed us how gravity pulled most of the materials toward the center of the
water which the water was representing gravity and the vermiculite that got pulled to the center was modeling the heavier more dense planets. The
vermiculite that was pushed away from the center represented lighter less dense

Hume Personal Identity Essay
With all of the influences within the world, it can often be difficult to determine who we are and how we became the person that we are today.
Although many people believe that from the time we are born, we begin to develop our own personal identities that will differentiate us from everyone
else within the world, others believe that our identities are a consequent of the influences that we encounter throughout our lives.
Personal identity is the concept that you develop about yourself that evolves over the course of your life. This also includes aspects in your life that
you do not have control over, such as where you grew up, the color of your skin, and your religious beliefs. According to David Hume, these influences
throughout our ... Show more content on Helpwriting.net ...
Some of these influences include personal struggles, race, living environment, parents and religion. As Anna Deavere Smith once stated "Identity is an
assemblage of constellations"("Anna Deavere Smith." BrainyQuote.com. Xplore Inc, 2017. 1 August 2017 ). Neil Gaiman's American God's, is a good
representation of personal identity because it demonstrates how a person's beliefs can relate to their personal identity as well. American Gods is a
fantasy narrative about a man named Shadow; as the story begins Shadow is serving a six year sentence in a county prison. Due to the death of his
wife Shadow is granted early release to attend the memorial service. Once Shadow is released from prison he takes a plane to Eagle Point, Indiana
and meets a man named Wednesday. After encountering with Wednesday a series of strange events occur. Later on readers find out that Wednesday is
a old god who wants Shadow to help him and the other old gods assert the newer gods. One of the central themes of this novel is faith. Gaiman
demonstrated how the early immigrants arrived to the United States with their faith. It was their beliefs that influenced the United States and made it
the country that it is today. Within his novel, Gaiman used the older and newer gods as a comparison to the older and newer generation. Gaiman used
actual mythological gods as character roles for

Dust Angel Nebula
The above image was posted on April 28, 2016 as NASA's image of the day. This is a dust angel nebula. A nebula is a cloud of dust and gas that is
visible when light reflects off of it. This nebula is about 300 light–years away from our galaxy, and is a collection of cosmic dust clouds. The nebula
gets the cloud–like display from light projected from the Milky Way which is then bounced off of the molecular clouds, where the dust releases UV
radiation as a red light/orange light (Space, 2013). The above image was posted on April 25, 2016 as NASA's image of the day. This is Supernova
Remnant Simeis 147, which is known as a spaghetti nebula. The strands of this nebula stretch about 150 light years; this nebula is estimated to be at
least 40,000 years old. This nebula is located 3,000 light years away ... Show more content on Helpwriting.net ...
This object is known as the Wolf–Lundmark–Melotte galaxy. A galaxy is a grouping of millions or billions of stars that are held together by a
gravitational pull, various gases and dust are also found throughout a galaxy. This galaxy was named after the three astronomers who discovered
it; this galaxy is known as a dwarf galaxy because it contains no more than a few million stars. This galaxy is located about 3 million light years
from the Milky Way (Astronomy Now, 2016). The above image was posted on May 3, 2016 as NASA's image of the day. The above image is a
photo of an aurora above Sweden. An aurora is a light display in the sky that typically occurs in high latitude regions, both in the northern arctic region
and the southern Antarctic region. This spectacular light show is produced when the magnetosphere is disturbed by solar wind. How the aurora
produced the magnificent green color is caused by oxygen atoms combining with ambient electrons in the atmosphere. What is so amazing about this
photograph is that there were several constellations in the sky that were very visible (Reddy,

The Invention Of The Hubble Telescope
Many years ago, astronomers never would have been able to know as much as they do today. With the many advancements in technology, we are now
able to retrieve information about the solar system, the galaxies around us, and many more things. As of now, there has been tons of new discoveries
all due to the Hubble Telescope. This telescope has done amazing things for astronomers. It has introduced new planets, stars, and many unknown
things. The Hubble Telescope has made amazing discoveries and has many more to find. There are four main topics. The first topic will be about the
astronomer Edwin Hubble. The second topic is about the telescope itself like when it was built, how, and how it works. The third topic will be about
the telescope's discoveries and the final topic will be the implications of those discoveries. All these topics show the importance of the Hubble
Telescope. Edwin Hubble was born in 1889 in Marshfield, Missouri. Biography.com states,... Show more content on Helpwriting.net ...
NASA then tried to figure out how to continue their plans. After the explosion it was hard for them to send the telescope into space. It was about four
years later before they finally sent the telescope into space. When they got the telescope into space they found something wrong with the telescope.
They had placed the primary mirror incorrectly causing the images to come out blurry. According to NASA's article "About TheHubble Space
Telescope", It was just slightly the wrong shape, causing the light that bounced off the center of the mirror to focus in a different place than the light
bouncing off the edge. The tiny flaw about 1/50th the thickness of a sheet of paper was enough to distort the view. Fortunately the telescope had been
built with interchangeable parts. So the astronomers were able to fix it and continue using the telescope to collect

Orion Nebula
The Orion Nebula contains one of the brightest star clusters in the night sky. With a magnitude of 4, this nebula is easily visible from the Northern
Hemisphere during the winter months. It is surprising, therefore, that this region was not documented until 1610 by a French lawyer named
Nicholas–Claude Fabri de Peiresc. On March 4, 1769, Charles Messier inducted the Orion Nebula, M42, into his list of stellar objects. Then, in 1771,
Messier released his list of objects for its first publication in Memoires de l'Academie.1 The Orion Nebula is one of the closest stellar regions to the
Earth. Using parallax measurements, it has been estimated that this nebula is only 1,500 light years away. In addition, the Orion Nebula is a ... Show

On April 9, 1998, Cornell University astrophysicist Martin Harwit published his discovery of the presence of massive amounts of water in the Orion
Nebula. This was the first time that water has been found in a star–forming region. The find demonstrates that water plays a vital role in star formation.
In addition, this discovery implies that water is prevalent in space. Harwit speculates that the water acts as a coolant, by carrying heat away from
the condensing clouds. It is believed that this process is necessary to slow down the particles in order to allow the compression of the particles into
new stars. 6 The discovery of water in the Orion Nebula will undoubtedly provide the basis for further study. More specifically, it will prompt
scientists to search for water in other regions of space at different stages of star formation. Then, if water is present in each, it may suggest that "the
oceans of Earth are older than even the planet that now contains them." 7 Page 3 Several unresolved problems remain concerning the Orion Nebula. The
fate of the protoplanetary disks, for example, is presently impossible to predict. Without a more detailed understanding of how planets actually form, it
cannot be assumed that the events within the Orion Nebula are analogous to the events that led to the formation of the planets in the solar system.
Furthermore, the detection of water in the nebula has revealed the need to revise the theory of star formation to

Nebulas Research Papers
Have you ever looked up at the sky on a clear night and wondered, "what else is out there?". What could possibly lie beyond the beautiful blanket of
stars that we see with our naked eye? Nebulas are one of many galactic phenomena that lie beyond the Kuiper belt. Mysterious and fascinatingly
beautiful sights to behold, they have more of a purpose than just painting the galaxy backdrop with color. I'm not a diehard fan of astronomy and to be
perfectly honest I find it difficult to follow most of the information I have learned. However, when I came across pictures and information on nebulas I
was instantly fascinated. From how and why they're formed, to what they do for the galaxy, I'm excited to take you on an intellectual journey though
nebulas.
At first glance, one might think that nebulas are made of light and that they have no ... Show more content on Helpwriting.net ...
This however, is far from the truth. Previously it was believed that the dark areas in the sky were just blank spaces between the stars, however it is
now known that these "blank spaces" aren't so blank after all (Koupelis p.367). Astronomers have discovered that they are in fact large clouds of dust,
or interstellar dust to be precise, that instead block out the light from the stars behind it (Koupelis p.367). The term nebula has its origin in the adjective
nebulous, which means "lacking definite form or limits" (Koupelis p.370). Much like the clouds that we see here on Earth, nebulas also come in all
shapes and sizes. Per scientists, nebulas are defined as being an interstellar cloud of dust, hydrogen, helium, and other ionized gases (Wikipedia).
These large areas of dust and other particles thrive in an area known as the interstellar medium and are formed when the interstellar medium goes
through a gravitational collapse (Universe). It's during this

Essay on Biography of Johann Elert Bode
Johann Elert Bode was born in Hamburg, Germany on January 19, 1747. His father was a merchant and his mother stayed at home with him and
his eight younger brothers and sisters. Bode never went to formal school, but his father was determined to teach him how to be a great merchant.
However, Bode didn't want to become a merchant. He was very interested in mathematics, geography, and astrology. He decided to go against what
his father was teaching him and pursue a career in Astrology instead. When Bode was a child he had a nasty eye infection that caused him to lose
most of his sight in his right eye. This didn't keep him from his studies or his astrological findings. When Bode was 18 his father died of a serious
illness. After this... Show more content on Helpwriting.net ...
Uranus was later found and its number is 19. Bode's law can not, however, accurately give the correct answer for Neptune and Pluto. While Bode's
name is in the name of the law he was not the person who created it. He was only the person who popularized it. Johann Daniel Titius was actually
the first person to first announce it. Bode had written about it in one of his studies but he had not credited Titius for his works, so people just
assumed that it was Bode's findings. Bode later gave Titius the credit he deserved, hence the second name of the law, Bode–Titius Law.
Bode has many other contributions to astronomy. He found, in total, four different celestial bodies and "rediscovered" three others. He discovered
M81, a spiral galaxy in Ursa Major; M82, an irregular galaxy also in Ursa Major; M53, a globular cluster in Coma Berenices; M92, another globular
cluster, in Hercules; M64, a spiral galaxy in Coma Berenices, this one was discovered by Edward Pigott then Bode rediscovered it 12 days later;
M48, an open cluster in Hydra, discovered by Charles Messier; and IC4665, an open open cluster in Ophiuchus, discovered by De Cheseaux. Also,
in 1776 Bode created his version of the theory of the solar constitution. Later in 1795, Sir William Herschel created his theory of the theory of the
solar constitution by tweaking Bode's version to fit his beliefs. Bode is the man whom came up with the planet name "Uranus" and it has been called
that ever since.
Bode had many

Old Earth Secular View Essay
Introduction People have been debating about the history of the earth for centuries. There are multiple different perspectives pertaining to the original
creation of the earth. The two most common perspectives include the old–earth secular view and the young–earth view. The old–earth secular view
believes that God has no scientific role in the creation of the earth. The young–earth view trust that God formed all the creation of the earth. The
purpose of this paper is to compare and contrast the old–earth secular perspective of nebular hypothesis and the young–earth's perspective of a six–day
creation.

A substantial difference between the two viewpoints is the belief in God. The old–earth secular view believes that God did not have any significant role
on the original creation of the earth. This also means that the Bible did not have an important impact on the history of the earth. The young–earth
perspective believes that all of creation was formed by God during the six days of creation. The main difference between the two main perspectives is
the original creation of the earth. The old–earth secular perspective trust in the nebular hypothesis. Therefore, people believe that the solar system of
the earth was created by a nebula. The young–earth's perspective believes that God created the earth in a six–rotational day period that followed by a
day of rest. One of the other significant differences between the two viewpoints is determining the age of the earth. The old–earth secular perspective
believes that the earth is over 4.55 billion years old. According to the Bible, the young–earth's perspective believes that the earth is only a few thousand
years old. This provides a clear description of the key differences between the old–earth secular perspective of nebular hypothesis and the young–earth's
perspective of a six–day

As of right now we can see 100 billion galaxies in our universe but then again that is only with the current telescope we have but as time goes by we
will make bigger and better telescopes. Over time we will see double to even triple the number of galaxies than we can see now. As for the Nebulae,
we cannot technically count all of them accurately. We can 't count all of the nebulae and galaxies but we can distinguish the different types. In my

These diverse types nebulas all have one thing in common and That one thing is how they are all attracted and created by some sort of gravitational
pull. Due to the excess amount of debris in the spiral arms of a spiral galaxies, such as the milky way. Hydrogen and helium from the spiral arms and
the debris that is still left from the big bang gives these nebulas a way to form their dust clouds. These dust clouds help create stars and once these
dust clouds are finished making a baby star the star pushes/ blows away the
nebulae so it can break through creating an open cluster of clouds which is also a type of nebulae that is formed, another name for Diffuse nebulae is
The Birthplace for stars.
Let 's start with a Globular cluster, this is a well–shaped well–rounded cluster that consists of one very bright and dense star That gets surrounded by
many smaller stars that were pulled in by its great gravitational pull. As explained in the last paragraph an open cluster is when a star blows through a
nebula causing the stars and dust to separate but still didn't fully fall out of its gravitational pull. Emission nebula are one of the most common nebulas
that are seen. This Nebula is emitted by a hot star that releases photons which is a quantum of light. A reflection nebulae is that nothing but an actual
cloud of dust

Nebulae: The Sagittarius Triplet
A Sagittarius Triplet
A nebulae as described in Fraknoi's Voyages to the Stars and Galaxies is "all objects that were not sharp points of light" (Fraknoi, page 384). The
Sagittarius Triplet is a group of three nebulae's famous for their bright red and blue hues, which is a main reason I choose this picture. There are
three nebulae in this picture and each is spectacular on its own but together the Sagittarius Triplet creates a visual buffet for the eyes. The dark reds in
particular are beautiful to behold and take up the majority of the visual landscape. These red colors are created by the emission nebulae by hydrogen
gas that is heated by the intense temperatures of present stars. The image made me feel the vastness of space and the endlessness of time. The
interesting layout of the nebulae creates a long stardust highway across the image, connecting the NGC 6559 and M8 nebulae. These three nebulae are
so bright they are routinely featured in telescopic tours of the Sagittarius constellation and the central Milky Way galaxy. M8 or the Lagoon Nebula and
M20 or Trifid were first cataloged in 1764 by Charles Messier (Kronberg).
The Trifid Nebula, M20, (at the upper right in the image) is a "rare combination of an emission and reflection nebula" (Koprolin). This colorful
contrasting nebulae is 5,000 light–years from Earth and 40 light–years across. Astar forming region in the plane of our galaxy, the Trifid illustrates
three different types of astronomical nebulae; red

Moon Observation
The Moon
The night of observing, the Moon was in the waxing gibbous phase. The Moon was formed when it collided with Earth as a planetesimal and now it
is an object that orbits Earth. The distance from Earth to the Moon is 238,855 miles away and is about 4.5 billion years old. (How) That night at
8:15 pm the telescope was places so we could see were the Moon was illuminated and where it was dark. On the left side of the Moon their were
some darker spots, were greyish in color, compared to the reset of the Moon. Even though it was partly cloudy with slight wind that night we could
see the craters on the Moon clearly. Through the telescope I saw craters with a typical bowel shape and others with more complex. Another type of
crater I saw was

Analysis Of Orson Scott Card. The Nebula And Hugo Award...
In the realm of speculative fiction, no author has had as great an impact on my worldview as Orson Scott Card. The Nebula and Hugo award winning
Ender's Game might be the best science–fiction novel I have ever read. The saga's central character, Andrew (Ender) Wiggin, is the pith of child
prodigies, for though his IQ is through the roof, his EQ, or emotional intelligence, is both immeasurable and unmatched. This was duly noted by his
second–in–command, Bean, who outperformed Ender in every test the Battle School had to offer. For all of his intelligence though, Bean could never
understand why everyone loved Ender so much. Indeed, even the reader falls in love with the infallibility of mankind's greatest hero, indestructible to
all but himself. Nevertheless, in spite of all the admirable characteristics of Andrew Wiggin, it is, ironically, one of the most fallacious characters that
should be hailed for his heroism. In regards to finding a more long term solution to to preventing the annihilation of the human race, it is Peter Wiggin
who is the true hero. Let us look at the some of the obstacles he faced before he was given the title of Hegemon.
The other children of John Paul and Theresa Wiggin absolutely despised Peter, and for good reason. Peter was a tyrant, ruling over Valentine and
Andrew with an iron fist. They often did whatever Peter wanted, fearing as to how he might react to rejection. With Ender, this was often found in their
Bugger game in which one must kill the

Protostar Nuclear Fusion
Just like humans, everything in the universe has a purpose. From the beginning of the moment anything is created into existence it grows and fulfills
its purpose. Stars are no different. Every day, stars are created by gravity which pulls the star together, the star builds up heat and pressure, and then
fusion begins. The process in which a star goes through is known as a star's life cycle. All stars start at the basic nebula phase, change to a protostar,
and go on to the main sequence star phase. After the main sequence star phase, there are two different divisions that are determined by the mass of the
star. If a star is known as a low–mass star it will have different life changes than a high–mass star. A low–mass star will become a ... Show more content

A white dwarf is the leftover core of a planetary nebula. A white dwarf is a low–mass star that is virtually dead. Since it is a leftover core it is
extremely dense. Inside of a white dwarf, no fusion takes place. The white dwarf will continue to give off light for about 20 million years and is
theorized that it will then become a black dwarf. As of now, no black dwarfs have been discovered, simply because the universe is too young. A
black dwarf gives off no light and is also cold, compared to the other stars in their life cycles. These black and white dwarfs burn through their fuel
very slowly, which would be why they last for millions of

Space 170 Bi Fall 2016
Grant Robbins Astronomy 170 BI Fall 2016 Actually observing the sky through the campus Steward Observatory telescope brought perspective to
just how lucky we are in Tucson to have such amazing resources to study the sky. The location of the telescope is amazing; right in the middle of our
historic campus which allows the general public accessibility to something that might otherwise be reserved for astronomers or scientists. Having a
21" telescope to view the night sky expands the field of view that wouldn't be as wide–ranging with an ordinary telescope. Having looked through
telescopes that were probably 4.5" previously, I wasn't really sure what to expect looking through a scientific version. Clear weather in late November
and having a night sky ordinance in Tucson also allows optimum viewing opportunities year round. "Thanks to a local ordinance that strictly limits
artificial–light pollution, Tucson supposedly has the darkest night skies of any city its size in the country." "Seeing Stars in Tucson 's Brilliant
Night Sky." The Washington Post. WP Company, n.d. Web. 05 Dec. 2016. "For a city of 500,000, Tucson is an astonishingly good place for

Orion Nebulae Research Paper
"Nebulae" inside the Milky Way Galaxy or separate, distant Galaxies?
Discoveries of what were termed "nebulae" began in the early 17th century. The first of these discoveries was the Orion Nebula, which looked like a
normal star to the naked eye. French scholar Peiresc discovered it in 1610 using one of the first telescopes to be made. Later, in 1656, Christiaan
Huygens observed the interior of the Orion Nebula and determined that it consisted of a compact quadruple star system instead of a singular star.
During the 18th and 19th century, nebulas were discovered even though astronomers were mainly scanning the sky for comets. Some major
astronomers who contributed greatly to the discovery of nebulas, among other things, during the 18th and 19th century were Messier and the Herschel
family. Though the instrumentation available to astronomers during the 18th and 19th century were highly advanced compared to earlier times, they
weren't advanced enough to detect the motion of extragalactic objects or their composition. This lack of precision instrumentation, and thus the
dissociation from motion of stars/star–clusters/nebulae, were the main reasons astronomers during this ... Show more content on Helpwriting.net ...
The ability to obtain the light spectrum of starlight was a big step, which allowed for the determination of motion in 3–D space.
Astrophotography–especially the dry plates–was a major technological development during this period which led up to the classification of nebulae as
distant galaxies/star systems. Telescopes could be mounted with plate–holders and spectrographs or studio cameras could be mounted with a prism on
top to show spectra of the objects being photographed. All these developments greatly contributed to early–20th century astronomers' ability to realize
that many nebulae weren't inside the Milky Way but rather were separate star systems of their

What Is The Veil Nebula?
Research from a star called Veil Nebula is being studied by scientists from NASA to discover how it has expanded since the eighteen years it has
been pictured. The Veil Nebula was left by a massive star and is one of the best supernova remnants. It was made with a fast–moving wave from an
explosion of dense gas that emits light. It was then blown into space by a dying star for it to shape into it's original form. In the Veil Nebula, there are
three different colors that represent something. The red is from the glow of hydrogen, blue represents oxygen and lastly, green is from sulfur. The
cooler gas is made from a shock collision that later developed into a huge structure. Scientists are comparing these pictures of the old pictures of the

Orion Nebula Essay
5/2018 The Orion Nebula For my report I chose The Orion Nebula, the easiest celestial object to see at the time I went to the observatory back in
March. This nebula harbors more than 3,000 stars that lie in a dusty region of mountains and valleys composed of mostly hydrogen. It is 1,500
light–years away and is the nearest star–forming region to Earth, making it the most effortlessly seen nebula of our skies (Hubble, 2006).
In further detail, the celestial object contains massive stars that shape the nebula and pillars of dense gas that may house budding young stars. The
heaviest stars at the center are called Trapezium because they are arranged in a trapezoid pattern (Hubble,2006). The stars near Trapezium are young
and still have protoplanetary disks, too small for us to see yet. At the bottom of the nebula there are brown dwarfs that couldn't be stars, this explains

After regions of space collapse on itself due to gravity it creates a region dense and hot enough for stars to form. These massive clouds of dust,
hydrogen, and helium provide the perfect place for many clusters of stars, old or young, big or small to flourish in. We can see further into Orion
through infra–red light and radio waves revealing the materials in the cloud. Observing Orion has allowed to see many stars, and their context, as the
bright massive stars form in the center and the low brown dwarfs are stuck on the edges. It can help us understand that depending on where the star
forms, can influence what type of star it will be. Additionally, the ability to locate exoplanets orbiting one of these stars, which we recently talked about

Low Mass Stars: Stellar Evolution
Stellar Evolution Did you know that stars don't stay as stars, they change over the course of time. Stellar Evolution is the star's life cycle. It includes
the birth, life, and death of a star. Stars die out due to their mass because their fate depends on it. Stars have two main masses so, each mass results a
different ending for each star. The two main masses are Low Mass and High Mass. These two masses of stars have different endings, so let us begin on
each of their life cycles.
Low mass stars are like the Sun. The Sun is a perfect example of this mass. All stars start out from a place called the Stellar Nebula. The Stellar Nebula

A Star's Life: How Does Life Of A Star Work?
How Does The Life Of A Star Work?
Matthew. M. Whittemore
Stratford. Ontario. Canada
Introduction
A star has 5 definite stages and 3 stages which can vary between stars. The 5 definite stages are a Nebula, a Star, a Red Giant, a White Dwarf and a
Red Dwarf. The stages that can vary are a Supernova, a Neutron Star and a Black hole. As the star goes through each stage, it can change size
dramastically. An example of this is a Red Giant, which is 100 time the size of the Sun, compared to a Red dwarf, only 1 tenth the size of the sun
(Life cycle). An interesting fact is "The closest star to Earth is Proxima Centauri, located 4.2 light–years away. In other words, it takes light itself more
than 4 years to complete the journey from Earth. If you tried to hitch a ride on the fastest spacecraft ever launched from Earth, it would still take you
more than 70 000 years to get there from here." (Interesting facts)

It is a large bright star with a cool surface. Just like the Sun, it eventually runs out of hydrogen fuel at its center. Red Giants have a diameter of
about 10 to 100 times the size of the Sun. The reason for why the Red Giants are so bright is because of its size, although there surface temperature
is less hot than the Sun's. If you were to measure the temperature, it would be about 2000 to 3000oC. Red Giants, very large stars, are also often
called SuperGiants. These stars sometimes have diameter of up to 1000 times the size of the Sun, also having more than 1 000 000 times the
luminosities of the Sun (Life cycle). These stars live for only a few thousand years to 1 billion years. Eventually the helium in the core runs out and
fusion stops. The star shrinks until a new helium shell reaches the

Charles Messier was a French astronomer who created an astronomical catalogue containing information on nebulae and star clusters, which was later
known as the 110 Messier objects. The catalogue was to help astronomical observers, particularly comet hunters.
As a comet hunter Charles Messier came across what are known now to be galaxies, nebulae, planetary nebulae and star clusters. With help from his
assistant Pierre MГ©chain, Messier composed a list of them. Messier done this to make it easier to differentiate between the comets they were looking
for and other objects. The list is made up of the objects that they could see from the north celestial pole to a celestial latitude ... Show more content on

M98 is an intermediate spiral galaxy, it is located approximately 44.4 million light years away in the Coma Berenices constellation. The M98 was
found by the French astronomer Pierre MГ©chain in 1781. Messier 98 has a blue shift, a right ascension of 12:13.8 (h:m), a declination of +14:54
(deg:m), a distance of 60000 (kly), a visual brightness of 10.1 (mag) and an apparent dimension of 9.5x3.2 (arc min). The morphological classification
of this galaxy is SAB(s)ab.
The image on the left is the Messier 98.
Galaxy morphological classification is used to divide galaxies into groups based on their appearance. There are multiple schemes used to classify
galaxies. The most famous is the Hubble sequence created by Edwin Hubble, which was later, expanded by Gerard de Vaucoulleurs and Allen Sandage.
The Hubble sequence is also known as the "Hubble tuning– fork" because of the shape it is represented by. The Hubble scheme divides galaxies into
three broad classes based in their appearance.

The Emergence Of Nebulae In The 19th Century
The concept of Nebulae has existed within astronomy for many hundred's of years, dating back to early Greek and Chinese civilizations. Although the
Greeks and Chinese did not have a clear idea of what they were observing, it is said that they could view these "clouds" in the sky. As time went by
the concept of nebulae from the time of early Greek's and Chinese up to recent days has changed considerably many times, following up an emergence
of theories and inventions. Nonetheless, we can see a kind of dialectical relationship between the inventions and the change in instrumentation (as the
changes in the first drive changes within the latter and vice–versa.) The existence of this circularity is often questioned and will be analyzed in depth,
along with a historical account of facts, through the next few pages of this paper. The concept of Nebulae also helped with the development of new
theories and ideas particularly around the 19th century. We can assume that nebulae were one of the factors that helped in the appearance of modern
contemporary astronomy. Galileo's thoughts addressed the first recent theories about the emergence of Nebulae in his book Assayer. Here he
mentions nebulae to be composed of different distant stars but he did not believe it to include clouds and other particles. Eventually at a later point a
catalogue of 103 Nebulae was published by Charles Messier. Although Messier's actual interest were comets he was one of the first to discover

Hazel Bishop: The Most Influential Female Feminist
Hazel Bishop was a female chemist and invented many things such as smear proof lipstick, skin care and many perfumes and cosmetics. She was one
of the most accomplished female chemists in the 1900s. Her inventions had an impact on the world of makeup. Hazel invented many things, showed
great characteristics and influenced us greatly.
Hazel was born in Hoboken, New Jersey and started her never ending career in 1929 when she attended Barnard College in New York and
graduated with a degree in chemistry. She originally wanted to be a doctor and go to MED school. She did graduate MED school but then moved
onto chemistry. In 1935 she started working as a research assistant for A.B cannon in a dermatological lab. In 1942 she worked **as an organic
chemist for the Standard Oil Development Company, making fuels for airplanes during World War II. While she was there she discovered the cause
of deposits affecting superchargers of aircraft engines. She is a huge inspiration to us to never stop living life to the fullest.
Hazel Bishop invented the very first smear proof lipstick. She called it "no smear lipstick" and used the quote "stays on you, not him". Women

One of those characteristics is motivation. She would have had to be extremely motivated in order to accomplish everything that she did. She would
have had to go through many years of schooling and she must have had a lot of trial and errors. She had to go through over 300 different experiments
in order to find a lipstick that she thought was suitable. Another characteristic that she showed was determination, she had to have been extremely
determined to be able to go through all of her science experiments and goals. It took Hazel many, many tries just to find out why the lip stick wasn't
smear proof in the first place. She had to be motivated and determined to go through with everything that she

Red Star Research Paper
When gazing upon the night sky, there are many small shining lights. Though these "small" lights are actually large balls of gas. These star's small
appearance are simply due to the fact that they are extremely far away from earth which makes us wonder what happens to them. As technology
progresses so does the discovery of science. Being able to observe the stars more efficiently, it is discovered that stars goes through their own cycle of
life, starting from birth to death.

In most cases a star will move into the planetary nebula phase, as an expanding, glowing shell of hot gas also known as plasma. This happens from a
low–mass star in the end of their red giant phase, becoming unstable. The exterior layer drifts away from it's core, which is now consider a white dwarf
star, due to stellar winds. If the dying star have a mass of over 8 suns, it will become a supernova. Just like a planetary nebula, the cause of it is
when a star runs out of nuclear fuel. From the massive star's lack of outward pressure to balance its inward gravity, the star collapses into the core
expelling a nuclear explosion. Also like the nebula, gas and dusts are scattered around space that will be used for the birth of future stars. At this point,
the former supergiant is either a neutron star or a black

Guardians Of The Galaxy Vol. 2: An Analysis
Guardians of the Galaxy Vol.2 is an amazing work looked through the religious concept of belief. In his book, Malory Nye mentions Richard
Gombrich's theory of cognitive and affective beliefs. Nye explains that "one major aspect of cognitive approaches is the attempt to understand
human actions (including religion and religious beliefs) with reference to the scientific study of the human brain" (Nye 2008, 110). In short,
cognitive is what we believe in, what we think and affective is what we do, our act (Nye 2008, 110). This theory can be wonderfully used to analyze
Guardians of the Galaxy Vol.2. At the very beginning of the film, Nebula is very strong on her point that she hates Gamora and her father and wishes

The Big Bang theory is a theory that states that the universe originated as a single mass, which subsequently exploded. The entire universe was
once all in a hot and dense ball, but about 20 million years ago, it exploded. This explosion hurled material all over the place and all mater and
space was created at that point in time. The gas that was hurled out cooled and became our stellar system. A red shift is a shift towards longer
wavelengths of celestial objects. An example of this is the "Doppler shift." Doppler shift is what makes a car sound lower–pitched as it moves further

Life Cycle of a Star
A star is born in a high–density nebula and condenses into gas and dust and contracts under its own gravity. Next, a region of condensing matter
will begin to heat up and star to glow, forming protostars. The temperature at this point is 5 million degrees centigrade. When this temperature is
reached, hydrogen fuses and forms helium. A star then begins to release energy which causes it to contract and shine. After millions of years, the
core of the star which is helium, contracts and a reaction begins to occur in a shell around the core. The core is at a high enough temperature for
helium to form into carbon and the out layer of the star expands, cools and becomes less bright. The core then burns out and the outer layer leaves
the core as a gaseous shell. The rest of the core cools and becomes a white dwarf and is less bright. When the white dwarf stops shining, it is called a
black dwarf.
Every now and then, a large star reaching the end of its life collapses in on itself, and then explodes very violently. The star explodes so violently that
for a few weeks the star can out shine its parent galaxy. This type of explosion is known as a supernova. Neutron stars form during a supernova.
What is a nebula?
Nebula are clouds of gas and dust many light years across. They can be formed by dying stars as in supernova remnants or planetary nebula. They can
be formed by young stars just emerging from their nurseries and beginning to

Caroline Herschel : A Pioneer Of Her Time
Caroline Herschel "was a pioneer of her time! She was an educated woman who would catalogue stars and nebula, and discover comets. She would be
the first woman astronomer to earn a salary, acquire honors, and be accepted into scientific organizations" (AmazingSpace). She became an
instrumental figure in the study of astronomy. Her work and achievements has broken monumental barriers and has expanded our knowledge of
astronomy. Some of her work and documentation is still used today, approximately two hundered years later. On March 16, 1750, Caroline Lucretia
Herschel was born to Isaac Herschel and Anna Ilse Moritzen in Hanover, Hannover, which is now day Germany. "Her father, Isaac, tended gardens
to support his family, yet he was also a clever musician" (Nysewander, 2016). He soon secured a position in the Prussian Army as a bandsman. As
Caroline grew up her father sought to teach her and her other five siblings music, but Caroline's mother wanted her to be her own personal house
servant, a real life Cinderella. Her father, who took pity on her, encouraged her to improve herself through music, mathematics, and astronomy. He saw
that she was very fascinated in learning, even though her mother did not believe in getting an education. Yet, her father would find ways to satisfy
Caroline's interest in education. "Caroline recalled that her father took her 'on a clear frosty night into the street, to make me acquainted with several of
the beautiful constellations, after we had

Born in Germany as Friedrich Wilhelm Herschel, it wasn't until his was 30 when he discovered what his true passion was. One night while he was
looking at the night sky with his sister Caroline, he discovered Uranus and several of moons around other gas giants. While he was alive, he
compiled a catalogue of 2,500 celestial objects that are still being used in today's society. While in his early life he mainly studied music with his
sister. His sister, Caroline was the first women to discover a comet, and the first women to get given a paid scientific position and to receive an
honorary membership into the Royal Society. William Herschel will come up with the Theory of The Evolution of The Stars.

Every night it was possible, he would sit and watch the stars with his sister Caroline, and his brother Alexander who came from Hanover. If the night
was overcast, he would position a watchman should the clouds move, he was to be summoned so he could observe the stars. When the weather
permitted he would watch the stars with his sister Caroline, who would record the information. In the daytime, he would monitor the construction of
the telescopes, many of which he sold for income to supply for the operation. [1]"His largest instrument, too cumbersome for regular use, had a mirror
made of speculum metal, with a diameter of 122 centimeters (48 inches) and a focal length of 12 meters (40 feet). Completed in 1789, it became one
of the technical wonders of the 18th century." His support mainly came from his sister, Caroline. Through countless hours of dedication and support
from his sister he was able to accomplish much in his lifetime.
Contribution's to Astronomy
Sir William Herschel accomplished a lot for astronomy. In 1781 he was able to discoverUranus with his own homemade telescope. With the help of
his sister, he was also able to discover over 2,500 celestial bodies that are still being used today. It was the first planet discovered that could not be
seen with the naked eye. Herschel wanted to name it after the king, but other astronomers did not agree. So they named it

Dying Star Research Paper
If you've ever wondered what a dying star looks like right when it's about to bite the dust, wonder no more: NASA has just released an image taken
by its Hubble Space Telescope which reveals the bright star known as Herschel 36 in its final death throes, a process that the agency says generally
takes tens of thousands of years.
What Does a Dying Star Look Like?
The picture posted by NASA shows Herschel 36 surrounded by a gas cloud that left its core exposed for the photograph. Emanating from the gas cloud
are radiant wisps of orange and blue hues, creating a truly spectacular sight. These colors are the result of ultraviolet light powering the gas cloud that
surrounds the dying star, and match the colors seen within the Ring Nebula. Because

Life Cycle Of Stars: The Life Cycle Of A Star
The Life Cycle of Stars Stars go through tremendous things in the course of their life. In a star's life they go through eight different phases. These
phases can take many years to go through. When a star is made up it starts needing. Gas and dust in space to form what is called a nebula. Nebulae
are the birthplace of stars. There are different types of nebulas one being an emission nebula. For example the Orion Nebula grows very brightly
because of the gas that is in it which is energized by the stars that have formed inside of it ("Life of a Star"). Another type of nebula is a reflection
nebula this is when starlight reflects off the greens of dust that are in a nebula. The last type of nebula is a dark nebula, these are very dense clouds of
molecular hydrogen that can either partially or completely absorbed light from stars.
So by definition a star is a globe of gas that produces its heat and light by nuclear fusion. They are born from a nebulae and are made up of mostly
hydrogen and helium gas. Surface temperature on a star can range from 2000В°C all the way up to 30,000В°C ("Life of a Star."). The colors of a star

When a star explodes it obtains the brightness of 100 million suns for a very short period of time. It is like a massive firework, it is apparently very
pretty to see. There are two types of supernovas one being a type one and the other being a type two. A type onesupernova occurs when gas from one
star falls into a white dwarf which causes it to explode. Type ii supernova is when a star that is 10 times as big as the sun suffers internal reaction
which ultimately results in the loss of its life. When a type ii supernova explodes can turn into neutron stars and black holes. Supernova is thought to
have elements are heavier than hydrogen and helium in

When a star explodes as a supernova,most of its matter is blown away into space to form a nebula. The ultra–dense remnants of the imploding core
which are lefts behinds are known as a neutron star, as it's electrons and protons are crushed together in the huge gravity to form neutrons. The
temperature inside a newly formed neutron star is from around 1011 to 1012 kelvin. However, the huge number of neutrinos it emits carry away so
much energy that the temperature of an isolated neutron star falls within a few years to around 106 kelvin. Then we have the average star , The
average star or intermediate–mass star, is a star with an initial mass of 0.5 to 8 times that of Earth's sun . Its spends most of its time on the main

gravity. The sun is an example of an average star . Next, is planetary nebula , planetary nebula is a growing and glowing cloud of hot gas/plasma
that occurs near the end of a low mass star's life. Actually it has nothing to do with planets . Planetary nebula's occur in the last stage of a dying star.

Difficult: Explaining Life As A Daughter Of Thanos
Difficult doesn't begin to explain life as a Daughter of Thanos. Nebula was taken from her family so young that she doesn't even remember then. She
assumes they look like her – blue and purple. They've got to be the same species, but beyond that? Nebula has no idea who they were. The odds that
they were left alive when she was taken are slim to none, and Nebula has long since lost any hope that she might find her species, let alone her family.
Maybe in the early days – times she doesn't really remember, not after Thanos yanked her brain out of her head – she had hope. Despite having
witnessed her parents' death at the Titan's hand, she still had hope that they would save her. A little girl's hope. During those early days, Thanos brought

Omega Centauri: The Origin Of Globular Clusters
As opposed to the more short lived and less dense colonies of young stars that group up to create open clusters, globular clusters exist as far greater
spherical fashioned collections of aged stars that contain many low mass stars, sometimes numbering among the thousands. Globular clusters are more
commonly found among a galaxy's centre where the vast majority of stars are. It is thought that globular clusters arise from large gas clouds early in
the creation of our universe and assist in the formation of greater galaxies.
Omega Centauri
Omega Centauri is a large globular cluster with an estimated star count between five and ten million. With a length spanning over 170 light years,
this globular cluster is the largest discovered in our galaxy. It's stars are so close that they are separated on average by only 0.1 light years, which in
contrast to other globular clusters makes Omega Centauri so different that astronomers suggest it's origin originally comes from the core of another
galaxy that was absorbed into the Milky Way, removing its outer layers.... Show more content on Helpwriting.net ...
While the vast majority are of similar class to our sun and bright yellow and white in colour there are also signs of red giants reaching the end of their
lives, as well as many small white dwarfs. Perhaps the more puzzling stars are the bright 'blue stragglers' (as depicted in the famous
Hertzsprung–Russell diagram), as these stars should have expired long ago in explosions called supernova. It has been suggested by astronomers that
these stars may be the merging occurring in such a crowded neighbourhood between lower mass

The Milky Way
Introduction
Our galaxy, The Milky Way, is composed of billion of stars of all ages, sizes and masses. A common stars, like our Sun, constantly gives out small
amounts of X–ray radiation, and larger burst of X–rays during a solar flare. Along with our Sun, stars shine as a result of nuclear reaction that happens
deep within their core. Causing chemical reactions that converts light elements into heavier ones and while releasing energy in the process. Energy
from the central region provides pressure to keep the star from falling apart under its own weight. The contracting cloud is then called a protostar. A
protostar is the earliest stage of a star's life. A star is born when the gas and dust from a nebula become so hot that nuclear fusion starts. Once a star
has "turned on" it is known as a main sequence star. When a main sequence star begins to run out of hydrogen fuel, the star becomes a red giant or a
red supergiant.
The Birth of Star (Nebulas)
All stars start as a nebula. Nebulas are large clouds of dust, hydrogen, helium and other ionized gases. Gravity then might pull the gas and dust in a
nebula together. In example of this is the Orion Nebula, which was located in excellent detail by NASA's Hubble Space Telescope and Spitzer Space
Telescope. A protostar is formed from the contracting clouds deep within these clouds that "gives rise to knots with sufficient mass that the gas and dust
can begin to collapse under its own gravitational attraction" (NASA, para.4). As

Among these are star maps, planispheres, filters, and various photographical devices. Starting with planispheres and star maps, these are used to aid in
manual telescope operation. The last telescope I discussed was a reflector telescope that used an Alt–Az mount, meaning locating celestial objects
relies fully on the operator's ability to use maps and star guides so get a lay of the land, or sky for this matter. Looking at the sky isn't near as easy
as it may sound. Much like how the Earth is covered in seventy percent water, the night sky is mainly stars. Without proper synchronization with the
night sky, you can be off in your observations by a long shot. Planispheres come in different editions depending on which hemisphere you reside in.

M27, was discovered by Charles Messier on July 12 1764. In 1784 William Herschel invented the name Planetary nebula after he had started
comprehensively scanning the deep sky and discovered a famous planetary nebula, the Saturn Nebula NGC 7009 in 1782. The nebula theory, states that
this theory is the most accepted evolutionary theory for the formation of the solar system from a cloud of gas and dust particles known as a nebula. The
process starts with a rotating cloud of gas and dust that contracts and flattens to form a disk around a star forming at its centre. Planets grow from the

Many people question how the solar system was made and a theory was developed by Emanuel Swedenborg, Immanuel Kant, and Pierre–Simon
Laplace. This theory provides more evidence for society to believe. The solar system is thought to be created from enormous spinning cloud. This
cloud was made up of gas and dust. The core of a cloud grew under the influence of gravity and as a result it became denser and hotter. Material was
collected into the core and the cloud increased in speed and became flat, almost like a disk shape. As the cloud became increasingly hotter the cloud
generated enough energy to create a nuclear fusion. The light gas was distributed far out in the solar system. This light gas left rocky materials and
metallic that had high melting points were left behind. These materials clumped together caused by mutual gravity and formed

Constellation : A Self Luminous Celestial Body
Moodle assignment
1. Define star, constellation
Star: A self–luminous celestial body consisting of a mass of gas held together by its own gravity in which the energy generated by nuclear reactions in
the interior is balanced by the outflow of energy to the surface, and the inward–directed gravitational forces are balanced by the outward–directed gas
and radiation pressures.
Constellation: An arbitrary formation of stars perceived as a figure or design, especially one of 88 recognized groups named after characters from
classical mythology and various common animals and objects.
2. Explain the usefulness of constellation identification
The identification of constellation can be useful because it allows us to navigate through the universe. By using the recognized constellations we can
travel through space and still find our way back; this can help in the future because when we start travelling to new planets we can use the natural road
that is in space.
3. Understand how to name stars within constellations
We can name the stars in a constellation by using their brightness. The brightest star we call alpha, the second brightest star we call beta, the third
brightest star is called gamma and so on, delta ..., some stars that are part of a constellations make a certain shape. An example of this is the Southern
Cross or the saucepan; these names come because they look like a saucepan or the Southern Cross.
