Astronomy Essay
One thing us as humans have never been able to fully understand is astronomy. Always having an
unexplained mystery, astronomy also has served as a way to keep time and predict the future. The
word "astronomy" is defined as the study of heavenly bodies, meaning anything in the sky such as
stars, galaxies, comets, planets, nebulae, and so on. Many people, if not everyone, is amazed by the
night sky on a clear, moonless night.
Astronomy dates back to ancient times when peoples such as the Babylonians, Egyptians, and
Chinese kept written records of astronomical events and occurrences. Today's seven day week
originates from the Babylonians' seven important bodies in the night sky: the Sun, Moon, Mars,
Mercury,...show more content...
A wide array of instruments is used to observe heavenly bodies today. These instruments include
optical telescopes which are used to magnify objects that emit visible light. Some celestial bodies
are very difficult or impossible to see with optical telescopes. To see these, we use radio, X–ray,
ultraviolet, or infrared instruments. An advantage of radio astronomy is the fact that radio waves
aren't stopped by the sun or clouds, therefore the stars can be observed at any time.
Our own solar system today is thought to have formed from a large, single cloud of dust and gas.
The center of the cloud became dense enough and created enough energy from contraction to spark a
nuclear reaction, forming the Sun. The remaining dust and ice in the cloud formed into the nine
planets we know of today. Other objects within the solar system include comets, asteroids,
meteorites, interplanetary dust and plasma.
Any star that we can see belongs to our own galaxy, the Milky Way. Stars do not exist outside of
galaxies in empty space, rather in galaxies which are groups of billions of stars orbiting the center of
the galaxy (Fradin 140). Every star has a color ranging from red to blue–white. These colors tell us
many things about each star. Also, a star's

Mayan Astronomy Essay
Before advanced technology, the Mayan observed the "Seven Stars" Sun, Moon, Mercury, Venus,
Mars, Jupiter, and Saturn using positional and horizon astronomy just like the Greeks and
Mesopotamians before them. Although the Mayans observations were made with the naked eye they
still had many interpretations associated with the sun and moon. They also independently
discovered octa eteris, a mesh between eight solar years with five Venus cycles of 584 days and 99
lunar months. Mayan warfare was also scheduled to get the most astrological benefits. To the Mayan
astronomy was a sacred activity.

This nebula is about 1/3 of a light–year thick, and five light–years across. Most nebulae are shaped
are more sphere shaped and most commonly a butterfly shape. Abella 39 is one extremely rare cases
in which the geometry is much simpler. This star, unlike its usual common shape is in the form of a
cat eye. This star is off center in the constellation about one tenth of a light–year.
Hercules is one of the largest constellations but doesn't have many brightly lit stars which makes is
hard to see in cities. This constellation is better viewed with the naked eye because of how dull its
stars are. Hercules is located in the southern hemisphere. Hercules contains a cluster of over 500,000
stars called the M–13 cluster. In mythology Hercules was believed to kill the Dragon, the guardian
of the garden of Hesperides.
In the winter me and my family like to take a short trip to Jupiter because of its nice, hot weather.
The vacation is always fun, but we try to stay away from the big red spot. It's always stormy there!!
It's only 5 planets away from the sun so my tan comes out very nicely and i show it off when i get
back to Earth. We always drive to the moons too, they're smaller and not as hot so i don't sunburnt
and we like to explore each community. It's a great time every

I Want To Be An Astronomer
When I grow up, I want to have a career in astronomy. Astronomers study planets, celestial bodies,
stars, and galaxies ("Summary"). I love answering difficult, deep questions and learning how the
galaxie works. I've always had an interest in outer space and in other worlds and would love a
career in which I can let my curiosity fuel me. It is important to understand the education or training
requirements, skills or talents needed, salary and benefits offered, and the duties for becoming an
astronomer when making this decision. Although most work in offices, some astronomers visit
observatories multiple times a year ("Summary"). While most hours are standard office hours, nights
provide the clearest view of the sky, therefore creating the perfect conditions for observing. This
means occasionally astronomers work nights in order to achieve their goals. Most of the time travel
is required in order to present ideas, use different equipment, or see different parts of the sky, but
where you work will depend on who you work for and what you are studying. If I indeed become
an astronomer my daily life will consist of developing theories, conducting scientific experiments,
and writing and presenting findings and proposals ("Summary"). For example, if I want to study
the effects unknown material will have on a satellite, I would develop a hypothesis and test it using
an electron particle accelerator. I will also deal with complex math calculations, which is good
because I enjoy

Introduction
Since man has looked to the heavens, he has used some form of identification to recognize the
"stars". Early man named the constellations he could see in his own ways. Even the ancient
Australian Aboriginals used stories of the stars to identify times of the year for different things, be it
song lines, migration, vegetation growth and ripening, the list goes on. The Australian Aboriginals
today still refer to the Milky Way's galactic centre and coal sack nebula, as they are seen from earth,
as the Emu; as it traverses the sky and ultimately out of visual, the song line changes and talks about
it crossing the land. The point being that man has always used some form of classification to discuss
objects within the...show more content...

Much like climatologists looking at global warming, gather data to see what has from looking at
core samples of the permafrost, using this data to make reasonable hypotheses about what our
climate will do in the future; we, humans, want to know more about what's happening in the
universe, including confirming the assumption that life exists beyond our solar system. To do
this, Astronomers when looking to the skies, are looking into the past. Why? One of the universal
constants, light. Light has a finite speed and as a result of the tyranny of distance, light can only
travel so far in a given Earth Year. This means that when we are observing galaxies today, we are
looking into the past, hundreds of thousands of years to billions of years ago. However, just looking
at galaxies is not good enough to be able to make these hypotheses. Wolf

Astronomy Observations
Astronomy Observing Report.
On Monday, June 26, I had the opportunity to observe some planets and stars with the help of
professor Lowry and his amazing telescope. What I saw and learned that night about Saturn, Jupiter
and the constellations was remarkable and complemented what I have being learning in my
astronomy course. The night of the observation was a clear night. The sun was out, it was 9:30 pm
and we could see the yellow and orange spectrum of the sun. This was a great example of what
happen to the Northern Hemisphere in June solstice, when days are longer. That bright night I saw
the planet Earth satellite "our beautiful moon" growing larger and on waxing crescent phase.
Looking in the telescope I saw the craters made by the impact

Socrates On Astronomy
Astronomer According to Socrates, a famous philosopher from Athens, Greece, "Man must rise
above the Earth–to the top of the atmosphere and beyond–for only thus will he fully understand the
world in which he lives." Socrates believes that astronomy can help other people understand the
world better. Astronomy is the study of space, and in order for someone to to be an astronomer,
they have to learn a lot of math and science and be good at it. Astronomy is not a big science field
either, but there are a lot of different people employing for it. Astronomy helps people understand
the world and that they are not the most important part of it, and that they are just a small part of it.
Astronomers have a lot they need to do because of their jobs. They have to study the origins of the
universe and what happens in space ("Physicists and Astronomers"). One thing they have to watch
for in space, is to watch out for comets that could possibly hit Earth. If they do not see a comet, they
can put many people at risk. If a large comet hits earth, it can end up changing the climate a little.
Astronomers do not look through telescopes to do this though. They mostly view space through
pictures the telescopes send to computers, and when they have to view at computers for a long time,
their eyes can end up strained ("Astronomer"). Because of how much work they have to do, they
have to be able to concentrate well, for longer periods of time. Some other things they need to be
able to do are

Astronomy Essay
I am excited to say that me and my team of astronomy researchers have discovered a correlation
between finding potential habitable star systems and a star's magnetic activity and X–ray emissions.
Our study, titled "An Improved Age–Activity Relationship for Cool Stars Older than a Gigayear",
was led by Rachel Booth, a PhD student from the Astrophysics Research Center at Queen's
University Belfast. Our data was gathered using NASA's Chandra X–ray Observatory and ESA's
XMM–Newton. NASA's Chandra X–ray Observatory is a telescope specifically built to detect X–ray
emissions from regions in the universe which exhibit very high temperatures such as stars. ESA's
Chandra X–ray Observatory is a telescope whose purpose is similar to that of NASA's...show more

ESA's XMM–Newton satellite follows an eccentric orbit and each telescope contains a mirror
module with 58 high–precision concentric mirrors to detect millions of sources and catch elusive
X–rays.
Through our research, we discovered results that linked a star's age to their X–ray emissions. We
found out that from the 24 stars analyzed, 14 of them had X–ray emissions that were discernible. We
were then able to calculate the stars' ages and from that, we recognized that there was a relationship
between their longevity and luminosity. Stars similar to that of our Sun are likely to emit less
high–energy radiation as they exceed 1 billion years in age.
While we made this amazing discovery, the reasons for this relationship are still unknown to us. We
are currently examining the causes and reasons this relationship may occur. A possibility of this is
through the reduction in spin rate of stars. The reduction in spin rate is faster in older stars than in
younger stars, which could explain the emission of less high–energy radiation as the stars grow
older. Another possibility this relationship can occur is because of the luminosity of X–rays. The
X–ray brightness declines quicker in older, more slowly–rotating stars than it does for younger,
faster ones.

Astronomy Essay
Astronomy
Astronomy is not just about the stars. Astronomy is about the constellations, the nine planets, the
sun and the moons. The solar system is very complex and has many extraordinary objects. There are
four different types of stars: Protostars, Bright Stars, Red Giants, and White Dwarfs. Protostars are
stars that are on the verge of being born. They are glowing clouds of dust and gas. Gravity pulls
on every atom moving them towards the center of the cloud of dust, which causes the Protostar to
collapse. Over a period of twenty million years the star begins to form and 10 million years after the
pocket of gas was formed, a star is born.
The second types of stars are called Bright Stars. They are formed when the new star...show more

Because it is so hot it gives off a glowing white light. This star is called a "White Dwarf" because of
its color. Out of the twenty stars that are closest to the Earth, two are White Dwarfs. The next big
thing about the solar system is the Planets. The nine planets play a big part in our solar system.
Astronomers have been studying them for a long time but there are still many things to learn about
them. The nine planets are Earth, Jupiter, Uranus, Pluto, Saturn, Neptune, Mars, Venus, and Mercury.
Mercury is also known as the planet of Hot days and Cold nights and it is the closest planet to the
sun. It has the shortest year out of all the other planets, which is 88 days long and is half the size
of Earth. Mercury orbits the sun at an average distance of 36 million miles. Daytime temperatures of
Mercury can reach up to 800 degrees Fahrenheit. At night they can get down as low as –279 degrees
Fahrenheit.
Venus, also known as Cauldron, has a yearlong period of 243 Earth days. It is the second planet
away from the sun and can reach oven–like temperatures up to 475 degrees Fahrenheit, even at night.
Venus is a very bright planet, totally surrounded by clouds. "It is the sunlight reflected off these
clouds that makes the planet so bright" (Ridpath 24). This planet is very unique compared to the
other planets because scientists discovered that Venus actually rotates backwards also.
Mars, also known as the red planet, has air so thin that a

Astronomy: A Career Essay
Timothy Ferris once said, "We live in a changing universe and few things are changing faster than
our conception of it. " Astronomy is a centuries old profession that has developed immensely
throughout history. As time has moved foreword, astronomy has moved with it. It has developed a
non–utilitarian use in modern–day society compared to its early use like navigation. As this
profession has developed, the competitiveness has also emerged due to several factors such as
government cutbacks. Astronomy is a rigorous job that requires the right degrees and personal
qualities to keep up with it. Even though astronomy has changed much throughout history in many
aspects, it retains the overall sense of wonderment and amazement that astounded others...show more

It is mentioned in the Encyclopedia Britannica that "Perhaps the single greatest effect that
astronomical studies have had on our modern society has been in molding its perceptions and
opinions. Our conceptions of the cosmos and our place in it, our perceptions of space and time, and
the development of the systematic pursuit of knowledge known as the scientific method have been
profoundly influenced by astronomical observations" (Evans). Astronomy works to answer the
fundamental questions humanity has about the universe and what else is out there. Astronomy has
changed humanity's method of thinking. Astronomy has opened the doors to discoveries and
advancements in other fields and areas in society. In C. RenГ©e James' paper titled What Has
Astronomy Done For You Lately, she states, "Engineer John O'Sullivan worked with others to
search for signals from evaporating black holes. He later extended that same technology to create
the basis for reliable wireless networking" (33). Without astronomy, wireless Internet would not
exist. It is the principles taken from astronomy and applied to other sciences that is one of the
reasons astronomy is so important to the world. Another example of astronomy influences other
inventions are optical mapping technologies. James say, "Optical mapping technologies developed
for the James Webb Space Telescope's optics system are also benefitting contact lens fittings and
laser eye surgeries"

Once upon a time, we believed the Earth was at the center of our universe. We were seriously

Optical and infrared telescope need to be in warm, high areas to be most effective. High altitude
is key, to avoid local weather and atmospheric activities. Building telescopes in on the west coast
in also popular to avoid pollutants in the air. Radio telescopes are most effective in low valleys.
These valleys help block radio rays from outside sources. Radio frequency interference continues to
become an arising problem with these kinds of telescopes. More of these telescopes will be built in
less populated areas (such as Australia) in order to insure efficiency.
Telescopes in space are an essential resource for detecting ultraviolet, X–rays, and gamma rays for
our research. With telescopes in space, we avoid atmospheric issues and get clearer images from
space. Unfortunately, these telescopes cost a lot of money. Their lifespan is also affected
depending on how much fuel the telescopes can carry. There is also a great risk when launching
these telescopes. Many of these missions have failed at the launch point. Once in space, these
telescopes can be damaged from debris in space, solar flares, or even cosmic rays. Size is also an
issue. It takes certain elements to make sure that these telescopes and their mirrors don't warp when
in space. This turns out to be yet another expensive factor. Maintenance and upgrades are usually
pretty simple for ground level telescopes. When it comes to the one's in space, it is nearly
impossible to maintain

Astronomy is a very interesting subject to me as there so much more out there that we can learn
about other than just Planet Earth. There is a lot to discover on Earth alone but there is even more
in the Solar System. New stuff can be discovered every day and there are astronomers and
