The Milky Way Galaxy Essay

The Milky Way Galaxy Essay
Many people who live on Earth are close minded to what is really out there in the universe. They
cannot even begin to fathom the vastness of it and how Earth is just a tiny little speck compared to
everything else out there. From the planets to the stars and out towards the edge of the unknown, we
can only see what science provides us with. From this, we know that we are nothing but a tiny
planet located in a solar system of millions in a galaxy of many more in the universe. A galaxy, also
called a nebula, consists of billions of stars, interstellar gas, dust, and dark matter which are all
bound to form a massive cloud in which we live in. Although it cannot be very well explained, dark
matter makes up at least 90% of a galaxy's mass. ... Show more content on Helpwriting.net ...
Once microwave radiation was discovered, studies improved on the Milky Way Galaxy. Its Doppler
Shift can be used to map the motion of gas in it. Also, with radio telescopes, hydrogen gas can now
be traced. When the Hubble Space Telescope was introduced in 1990, that made exploring space so
much easier and more efficient. That's how we discovered so much about our universe– including
galaxies!
The Milky Way received its name from the milky, white band of stars that go across the celestial
sphere visible from Earth. However, in Greek mythology, it is said that Zeus placed his mortal son,
Heracles on Hera's breast while she was asleep so the baby could breastfeed to become immortal.
When she had awoken to a strange baby feeding off of her, she pushed Heracles away and a stream
of milk sprayed through the night sky forming the Milky Way. It is estimated that about 200 to 400
billion stars are located within the galaxy. The Milky Way is also one of the larger galaxies that have
a circumference of about 300 thousand light–years! There are many types and morphologies of
galaxies. First, there are elliptical galaxies which have elongated structures, like an ellipse. An

The Phoenix Constellation
I have chosen the phoenix constellation because I am very fascinated about the phoenix it self.
Albus Dumbledore is supposed to have had one or still has one if he is still alive. The phoenix tears
can heal as far as I know heavy vullnaries. It is in general a very trustful beeing. There must be a
connection from the beeing to the constellation.
The Phoenix constelation moves around the part of the southern sky depending on the position of
viewing.

in ancient Babylonia and Egypt as the Egyptians had a bird called Heron which could be in the

Probably RA eather had a phoenix when he was short after the creation of the universe and earth on
earth or he appeared as Phoenix reminding the Ancient Egyptians of its role as God kind as Phoenix
who has a long lifetime and is reborn in an element of its self sun similar to fire. He appeared to be
part of a conclusion of Gods all in different parts if the universe. As the ancient egyptians beleaved
there is only on phoenix at a time. He took part in history and reminded the believers that they
should keep history and report there story. This was also necessary because they or at least part of
them beleaved that it only appears once in 500 Years. Later the Gods found each other in the
constellation of phoenix as they founded it in an inter galactic collection of gets. Actually those
gates began existing as gates as the God RA in his presance as phoenix started to cry because he
needed a way to contact other gods through different dimensions. His tears created stars. Since the
stars are created he can contact the other gods through different dimensions and far galaxies using
the gates. The other Gods started using them because he cried that loud and his tears were so
beautiful and clear that they cought them up and so there energy transferred into the

A Spiral Galaxy
NGC 1672, a barred spiral galaxy located in the direction of the southern constellation Dorado lies
more than 60 million light–years away. This is a spiral galaxy that's composed of stars in a central
bar–shaped design. NGC 1672 is a member of the Seyfert galaxy, which was named after famous
astronomer, Carl Keenan Seyfert, who extensively studied galaxies with active nuclei in the 1940s.
In the middle of NGC 1672's galaxy, it contains a high surface brightness bar from which four wire–
like spiral arms extend outwards. This galaxy's symmetrical look is mainly formed by the four
extending arms of which are bordered with the most spectacular dust lines that extend out from the
center. Unlike the normal galaxies, NGC 1672's arms do not fully spiral all the way to the center.
The arms are actually connected to both ends of a linear–like bar of stars encompassing the nucleus.
In fact, the arms extending from the middle of this galaxy is the main reason I was drawn to this
image. The arms with the beautiful pinkish purple rays look like an Eastern Redbud blossoming in
the months of April–May, which have always caught my eye since I was a little kid. Visible from the
Southern Hemisphere, NGC 1672 shows extraordinary regions of star formations. Near the edges of
this galaxy's galactic bar, the greatest clustering of star formations can be found. The picture taken
of NGC 1672 above was photographed with Hubble's Advanced Camera for a survey in August of

Galaxies And The NGC 1512 Galaxy
*Galaxies are beautiful and grand systems that exist in the universe. They come in different shapes
and sizes, and they exist light years away. In this essay I will be writing about galaxies and touching
upon my favorite galaxy the NGC 1512 Galaxy. Which has a prism of color in the center of its
barred spiral galaxy, and it is a neighbor to our Milky Way.
*What is a galaxy? According to Nasa.gov, a galaxy "is a huge collection of gas, dust and billions of
stars and their solar systems", (Site 1). Everything that makes up a galaxy is supported through
gravity and they can contain somewhere around a million stars and can range from a few thousand
to a couple hundred thousand light years across. The website CoolCosmos.edu states that galaxies
can either be found alone, in pairs or in large groups called clusters. They also say that galaxies can
be broken down into three basic types: spirals, elliptical and irregular, (Site 2). ... Show more

They are broad rotating disks of stars and nebulae, encompassed by a layer of dark matter. A
majority of spirals have a crown of stars and star clusters either atop or below the disk. Spiral
galaxies tend to have copious amounts of bright bars stars and material that cut right across their
central section called "barred spirals". Galaxy NGC 1512 is a barred spiral galaxy near the
Horologium constellation. Furthermore, numerous spirals can hold supermassive black holes inside
the base of them. These galaxies have subgroups, which can be defined by defined by their bulges,
spiral arms, and how compressed those arms are, (Site

Milky Way Research Paper
The Milky Way is the galaxy that contains our solar system. Its name " Milky" was derived from its
appearance as a dim glowing band arching across the night sky whose individual stars cannot be
distinguished by the naked eye. The Milky Way is a barred spiral galaxy, which means it spiral out
from the middle. The first and most obvious thing to talk about is how it was formed. It began as an
oversized mass left behind after the big bang. The Big Bang theory is an effort to explain what
happened at the very beginning of our universe. over densities were the seeds of global clusters that
formed many of our galaxies. Within a few billion years after the first birth of the star, these over
densities had enough mass to be spinning relatively fast. As the gravitational pull, pulled stars
towards it, it began to gain size and mass. So how long has it been formed ? Based on a process of
nucleo cosmochronology, it it said to be 12.5 ± 3 billion to 13.8 ± 4 billion years old. That is a lot of
time to gain mass, and to form into a galaxy. It consists of a bar–shaped core region ... Show more

First, 90% of it is totally invisible. Scientist find the relative mass of our galaxy, as I stated above.
They then went and took all of the masses we can see and found the combined mass of all of those.
They thought that maybe they would roughly have 50% of the mass of the galaxy. Wrong, they had
only seen 10% of the total mass of the galaxy, making nearly 90% of it invisible to us. The spiral
arms of the Milky Way are an illusion. The arms we see, we would think that there aren't any stars in
between the spirals. We are wrong again. There are just as many stars in between the spirals than
there are in the spirals themselves. So why do we see spirals ? The spirals are like a highway for
stars, where the relative density is enhanced, making the stars shine brighter than in between the

The Most Incomprehensible Thing About The World
"The most incomprehensible thing about the world is that it is comprehensible."– Albert Einstein.
Universe is a mysterious world that is incomprehensible to clarify. However, through intelligence,
intuition and ingenuity, it affected Humans to perceive the uncharted world they live in and make it
comprehensible. After the tremendous explosion, hundreds of billions of stars were swirling and
interacting with each other by gravity, constituting a galaxy. In the midst of chaos, there was the
Milky Way galaxy, our galactic home. Unlike a regular spiral, the Milky Way galaxy is a barred
spiral that was comprised with two minor arms and spurs. One of the spurs, Onion Arm, contains the
sun and the solar system. There are eight planets in our solar system and they are all unique. Yet, out
of all the planets, Saturn, perplexed many astronomers with its discoveries. First and Foremost, the
"chemical compounds in its upper atmosphere color, its cloud bands in subtle shades of ivory and
broad, lacy rings that encircle Saturn", captivated the astronomers with its charm. Although, ancient
Greeks were able to detect Saturn thousand years ago, no one conceded that Saturn had its rings,
until Galileo perceived them with his telescope in 1610. Indeed, the discovery of Saturn left its mark
on the history, where astronomers had an abysmal quarrel whether it was heliocentric or geocentric.
II. Historical Context In fact, the oldest written records validating Saturn was attributed to
Assyrians.

M98 Observation Paper
For my observing project I chose to do Messier 98 (M98). I chose M98 because I am absolutely
fascinated by galaxies, and I think spiral galaxies look the coolest. M98 is located in the
constellation Coma Berenices and it is in the Virgo Cluster of galaxies. A French astronomer, named
Pierre Mechain, on March 15th 1781, discovered M98 and then Charles Messier measured its
position and catalogued it on April 13, 1781. M98, also known as NGC 4192, is located at a Right
Ascension of 12h 13m 48s and at a Declination of +14° 54' 2''. This means M98 rises at
approximately 16 PDT and sets at approximately 4 PDT, and is right overhead at approximately
22:00 PDT. It has apparent size of 9.8' by 2.8', an inclination of 74°, an apparent magnitude of 11.0,
and it is located approximately 44.4 million light years away. Also M98, unlike most other galaxies,
which are usually red shifted and travelling away from us, is actually blue shifted and approaching
us at about 140 km/s. Also M98's maximum rotational velocity, which is at the very edge of its
radius, is approximately 280 km/s. To observe M98 I took a seris of exposures in clear, red, green,
and blue filters. I used these filters ... Show more content on Helpwriting.net ...
This is hard to determine though due to M98's hard inclination of 74°. M98's nucleus is active and
this means that M98 is an active galaxy. To have an active nucleus a galaxy's center has to be more
luminous than the rest of the galaxy on most of, or all, of the electromagnetic spectrum, but M98 is
also considered a low–ionization nuclear emission– region type galaxy (LINER). This type of
galactic nucleus has a specific kind of spectral line emission. The spectral lines are mostly from
weakly ionized and neutral atoms. M98 is also believed to have a supermassive black hole at the
center due to it being active, and emitting a lot of

Milky Way Research Paper
The Milky Way is the galaxy that contains our Solar System. The descriptive "milky" is derived
from the appearance from Earth of the galaxy a band of light seen in the night. From Earth, the
Milky Way appears as a band because its disk shaped structure is viewed from within. Galileo
Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early
1920s most astronomers thought that the Milky Way contained all the stars in the Universe.
Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis and an
observation by Edwin Hubble showed that the Milky Way is just one of many galaxies.
The Milky Way is a barred spiral galaxy with a diameter between 100,000 and 180,000 lightyears.

Reverberation Map Analysis
Seyfert galaxies are one of the two largest groups of active galaxies, along with quasars. They have
quasar–like nuclei (very luminous, distant and bright sources of electromagnetic radiation) with very
high surface brightnesses whose spectra reveal strong, high–ionisation emission lines, but unlike
quasars, their host galaxies are clearly detectable. Seyfert galaxies account for about 10% of all
galaxies and are some of the most intensely studied objects in astronomy, as they are thought to be
powered by the same phenomena that occur in quasars, although they are closer and less luminous
than quasars. These galaxies have supermassive black holes at their centers which are surrounded by
accretion discs of in–falling material. The accretion ... Show more content on Helpwriting.net ...
This is confirmed by the fact that the narrow lines do not vary detectably, which implies that the
emitting region is large, contrary to the broad lines which can vary on relatively short timescales.
Reverberation mapping is a technique which uses this variability to try to determine the location and
morphology of the emitting region. This technique measures the structure and kinematics of the
broad line emitting region by observing the changes in the emitted lines as a response to changes in
the continuum. The use of reverberation mapping requires the assumption that the continuum
originates in a single central source. For 35 AGN, reverberation mapping has been used to calculate
the mass of the central black holes and the size of the broad line regions. In the few radio–loud
Seyfert galaxies that have been observed, the radio emission is believed to represent synchrotron
emission from the jet. The infrared emission is due to radiation in other bands being reprocessed by
dust near the nucleus. The highest energy photons are believed to be created by inverse Compton
scattering by a high temperature corona near the black

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.

The galaxy contains the Solar System, with more than 200 billion stars and at least 100 billion
planets. The name "milky" comes from the dim disk–like appearance the galaxy has when observed
in the night sky. It is a barred spiral galaxy with four major arms and a diameter of 220 000 light–
years. The mass of the Milky Way is approximately more than 400 solar masses. The center,
Sagittarius A, is located about 26 000 light–years from Earth and contains a supermassive black
hole. The other galaxy involved in the future collision is the Andromeda galaxy, or M31. There are
about 1 trillion stars and could possibly contain more dark matter than the Milky Way. Its name
comes from the constellation of Andromeda, which originated from the mythological princes
Andromeda. It is a spiral type galaxy with at least two spiral arms and a diameter of 260 000 light–
years. The mass of Andromeda is approximately 400 billion solar masses.

song lines, migration, vegetation growth and ripening, the list goes on. The Australian Aboriginals

Edwin Hubble Research Paper
Life and Discoveries of Edwin Hubble
Edwin Hubble was a pioneer astronomer who highly attributed to the study of the physical universe.
He completely changed our understanding of the universe by demonstrating that our universe is
larger than what was previously thought and that the universe is expanding (Brown, n.d.). These
discoveries were also some of the first to support the theory behind the creation of the universe, the
Big Bang (Sandage, 1989).
Edwin Powell Hubble was born November 20, 1889 in Marshfield, Missouri, U.S. (Edwin P.
Hubble, 2006). Shortly after his birth, his parents Virginia James and John Hubble along with their
children moved to Wheaton, Illinois where Edwin would grow up. Growing up, Edwin Hubble was

However, Hubble understood that teaching was not for him, so after one year he wrote to Moulton,
his astronomy professor at University of Chicago, about rejoining the university as a graduate
student. Hubble studied at Yerkes Observatory in Wisconsin, which was equipped with a 40 inch
refractor. His first discovery was made when comparing images of nebulae over a few years. He
noticed that there were faint changes occurring in the nebulae demonstrating that changes in nebulae
could occur (Osterbrock, 1990).. Hubble completed his doctorate in 1917(Brown, n.d.), to which his
thesis was titled "Photographic Investigations of Faint Nebulae." His thesis would foreshadow many
of his future discoveries as it emphasized that the nebulae exist outside of the Milky Way and
possibly millions of light years away (Osterbrock, 1990). Upon completion of his Ph.D., Hubble
was offered a job at Mount Wilson Observatory near Pasadena, California (Brown, n.d.). The
observatory was home to the most powerful telescope in the world at that time, the new 100–inch
Hooker Telescope. It was here where Hubble would stare at the stars and discover so much about the
cosmos (Osterbrock,
