Introduction
At the beginning of the course we were asked to choose a “Cosmic Target”, which is something in space that we wanted to know more about. I chose the Milky Way Galaxy as a single unit. I wanted to know why it was, what it was and where it was going. All of us of course know where the Milky Way is, it is our home. A part of our cosmic address, and up until recently it was the biggest thing that we could imagine. As far as where it is in the universe, it is in The Local group, which is a sub-cluster, located in the Virgo Super Cluster. All of this is somewhere around 13 Billion years after the Big Bang.
History of Discovery
Democritus, a pre-socratic philosopher, is credited with first hypothesizing that the bright band which runs across the night sky may be a close cluster of stars. Democritus lived around the year 400 BC. It wasn’t until the 17th century that Galileo Galilei provided proof that the galaxy was made up of many stars, using an early telescope. Then in the 18th century a man name Thomas Wright postulated that the galaxy what actually a gigantic rotating clus...

  • Alan Lightman's Our Place In The Universe

    Many of the heavenly bodies were considered to be the representations of deities. The master of reason, Aristotle, stated once long ago that everything was made of only five elements the final being what makes up the heavenly bodies, after all they lacked the proper technologies to know differently. It was Galileo in 1610, using his telescope, that found dark spots on the sun. So as technological innovations occur our understanding of physics and astronomy grow. Newton in 1687 discovered the laws of gravity, suggested that all the solar and stellar bodies operated the same.

  • The Cosmic Perspective Neil Degrasse Tyson Analysis

    556 Words  | 2 Pages

    In the article The Cosmic Perspective by Neil deGrasse Tyson he examines a range of topics from human life coming from Mars to how our perspective of the universe relates to religion. In the year 2000, a new space show opened at the Hayden Planetarium called Passport to the Universe, which compared the size of people Milky Way and beyond. While a show like this might make someone feel minuscule and insignificant, Tyson says that seeing the size of the universe actually makes him feel more alive not less and gives him a sense of grandeur. I agree with his idea that looking at us as a people in comparison can actually give you a sense of grandeur. However, when I compare myself to the vastness of space, it puts events on Earth in perspective while showing how influential we can be as a people even if we are small.

  • Discussing the Hypothesis of a Supermassive Black Hole in the Milky Way Galaxy

    515 Words  | 2 Pages

    There is evidence that supports the hypothesis that the Milky Way Galaxy has a massive black hole at its core. At the center of our very own galaxy is a mysterious source of energy. Vast amounts of radiation pour from this compact source which may be a Supermassive Black Hole. Astronomers found an intense radio source with strings of other radio sources clustered about it in the direction of the galactic center. The intense source was named Sagittarius A because the center of the galaxy lies in the direction of the constellation Sagittarius. The position of Sagittarius A as has been observed through radio telescopes around the world seems to be very near the dynamical and gravitational center of the galaxy. Based on its high luminosity and radio spectrum Sagittarius A is neither a star nor a pulsar. It has a luminosity of 5 stars but is smaller than our solar system. Also, it can’t be a supernova remnant since it is not expanding. The strongest evidence that it is a Supermassive Black Hole come...

  • Shapley Vs. Curtis Argumentative Essay

    461 Words  | 1 Pages

    Two men named Harlow Shapley and Heber Curtis has a debate in 1920 that is still important today for changing how we think about galaxies. They talked about five important things. The first thing they debated was how big our galaxy, the Milky Way, is. Shapley said that the Milky Way was much bigger than we first thought, 100,000 light-years across, and that, because it was that big, it had to be the only one. Curtis said the the Milky Way was smaller than that, and that other galaxies existed past ours. They were both right and both wrong. Shapley was right about the size of the Milky Way, and Curtis was right about there being many more galaxies in the universe.

    Let there be dark Darkness, the first thing you see when you wake up and the last thing you see when you drift asleep. Now imagine a darkness darker than you've ever known. This is what Paul Bogard wrote about, the devastating lost of darkness that has happened to our world. Bogard connects to his audience by using statistics, facts, and emotion. First off, using statistics makes the author of the arguing paper seem logical and intelligent on what they're writing about.

  • How Are Galaxies Similar To The Milky Way

    1792 Words  | 4 Pages

    The Milky Way has 20 satellites (dwarf galaxies and globular clusters) that lie on a single plane perpendicular to the Milky Way’s disk. The Milky Way’s galaxies lie on a plane. The Milky Way’s and other large galaxies’ satellite galaxies should be distributed evenly around the large galaxy. However, almost half of Andromeda’s satellite galaxies lie on a single plane, and they all revolve around Andromeda in the same direction. 15/27 of the observable Milky Way satellite galaxies lie on the same plane, and 13/15 of these satellites were orbiting in the same direction.

  • The Small but Vast Field of Astronomy

    1116 Words  | 3 Pages

    Astronomy is a field where one looks into the great expanse of space and tries to find something that will bring the world a little closer to fully understanding the universe. The road to becoming an astronomer is not easy, as one must get an excellent education, hope that there are actual job openings, and then obtain a steady position. In order to be an astronomer, it is required to have a doctorate’s degree in either astronomy or physics (“Physicists and Astronomers”). After finishing their studies, an astronomer can really only hope to be lucky and secure a position working for the government, a university, or a college (“Astronomer Job Description”). If they somehow find a job, an astronomer’s job varies heavily depending on where they are employed (“Careers in Astronomy”). The first step with nearly every career is experiencing an education that will help them succeed through life.

  • Stellar Evolution

    2295 Words  | 5 Pages

    A star begins as nothing more than a very light distribution of interstellar gases and dust particles over a distance of a few dozen lightyears. Although there is extremely low pressure existing between stars, this distribution of gas exists instead of a true vacuum. If the density of gas becomes larger than .1 particles per cubic centimeter, the interstellar gas grows unstable. Any small deviation in density, and because it is impossible to have a perfectly even distribution in these clouds this is something that will naturally occur, and the area begins to contract. This happens because between about .1 and 1 particles per cubic centimeter, pressure gains an inverse relationship with density. This causes internal pressure to decrease with increasing density, which because of the higher external pressure, causes the density to continue to increase. This causes the gas in the interstellar medium to spontaneously collect into denser clouds. The denser clouds will contain molecular hydrogen (H2) and interstellar dust particles including carbon compounds, silicates, and small impure ice crystals. Also, within these clouds, there are 2 types of zones. There are H I zones, which contain neutral hydrogen and often have a temperature around 100 Kelvin (K), and there are H II zones, which contain ionized hydrogen and have a temperature around 10,000 K. The ionized hydrogen absorbs ultraviolet light from it’s environment and retransmits it as visible and infrared light. These clouds, visible to the human eye, have been named nebulae. The density in these nebulae is usually about 10 atoms per cubic centimeter. In brighter nebulae, there exists densities of up to several thousand atoms per cubic centimete...

  • The Merging of Galaxies

    713 Words  | 2 Pages

    A dwarf galaxy is, “a small galaxy composed of up to several billion stars—a smaller amount compared to our own Milky Way’s Galaxy’s 200-400 billion stars” (Wikipedia). On February 23, 2014, it was reported that two galaxies that had once orbited around the Andromeda Galaxy were merging together. The collision created a stream of stars in one of Andromeda’s dwarf galaxies, Andromeda II. Researchers then observed the stream of stars by separating them into categories and trying to analyze which could be members of Andromeda II versus those that could be “dwarf foreground stars from the Milky Way halo” (Amorisco et al, 2014, p 4). Because the stream of stars is located on an area of Andromeda II that has limited brightness, researchers found 14 “high-probability contaminants” in a region of the stream with “stars that [were] significantly more likely to belong to the Andromeda II population” (Amorisco et al, 2014, p. 4). By measuring the characteristics of the stream, researchers were able to conclude that it displayed “remnants of a merger between two dwarf galaxies…illustrating the scale-free character of the formation of galaxies, down to the lowest galactic mass scales” (Amorisco et al, 2014, p. 1).

  • Galaxies in Our Universe

    757 Words  | 2 Pages

    The Universe is a collection of millions of galaxies and extends beyond human imagination. After the big bang, the universe was found to be composed of radiation and subatomic particles. Information following big bang is arguable on how galaxies formed, that is whether small particles merged to form clusters and eventually galaxies or whether the universe systematized as immense clumps of matter that later fragmented into galaxies (Nasa World book, 2013). A galaxy is a massive area of empty space full of dust, gases (mainly 75% Hydrogen and 25%Helium), atoms, about 100-200 billion stars, interstellar clouds and planets, attracted to the center by gravitational force of attraction. Based on recent research, 170 billion galaxies have been estimated to exist, with only tens of thousands been discovered (Deutsch, 2011).
