  • Milky Way: Galaxies Organized And Distributed Within The Universe

    contain? The Milky Way is a barred spiral galaxy, which looks like a pinwheel. At times, people can look up to the sky and see the faint band of light, the glow of stars in the galaxy’s disk, which gave the Milky Way its name. The galaxy is of an average size, 100,000 light-years across and 1,000 light-years deep. It contains about 500 billion stars and many planets. The center of the galaxy contains a supermassive black hole, which is the cause of our galaxies spiral space. Within the galaxy, there are four main spiral arms, known as Perseus, Cygnus, Centaurus, and Sagittarius; each arm expands into smaller branches of arms. The Milky Way is contained within the Sagittarious arm in the Orion arm branch. There are also a bunch of ancient stars, globular clusters, that orbit the halo of our galaxy. Along with the billions of stars and planets, the Milky Way also contains many solar systems and smaller black holes, although scientists do not have much proof of such existences, scientists can reasonably explain their hidden presence. 2.…

  • Edwin Hubble's The Realm Of The Nebulae

    A spiral galaxy is a certain kind of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, forms part of the Hubble sequence. Spiral galaxies consist of a flat, rotating disc containing stars, gas and dust, and a central concentration of stars known as the bulge.(Sloan) Spiral galaxies resemble spiraling pinwheels, nearly 77% of space consists of spiral galaxies. Though the stars and other visible material contained in such a galaxy lie mostly on a…

  • Messier 81 Research Paper

    3031 or Bode's Galaxy) is a spiral galaxy about 12 million light-years away in the constellation Ursa Major. Due to its proximity to Earth large size and active galactic nucleus] or supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy's large size and relatively high brightness also make it a popular target for amateur astronomer. Messier 81 was first discovered by Johann Elert Bode in 1774.Consequently, the galaxy is sometimes referred to as…

  • Messier Galaxy Research Paper

    messier galaxy is galaxy that is seventeen million light years away. This galaxy can be seen in the constellation Hydra. This galaxy is a spiral pinwheel galaxy and is also one of the brightest galaxies in the sky. The galaxy messier 83 was founded in February 23 in 1752 by Nicolas Louis de Lacaille. Lacaille found the Messier 83 galaxy off of the Cape of Good Hope. In March of 1781 Charles Messier added this galaxy to his catalog of nebulas objects, known as the messier catalog. Later on June…

  • Argumentative Essay On Galaxies

    finding new galaxies, planets asteroids, and more. But today, that's not what we are going to talk about. We’re going to talk about galaxies. Have you ever wondered what a galaxy really is? In the early 1900s, astronomers . Astronomers argued about spiral shaped, gas, dust were getting closer to discovering galaxiessome star vast cloud found in the night sky. In 1919, Edwin Hubble, an astronomer found the answers. Hubble used his 100-inch mirror and stood on top of Mount Wilson in California. He…

  • Edwin Hubble Essay

    Hubble identified a type of “variable star” called a Cepheid in the Andromeda nebula, or known today as the Andromeda galaxy. Hubble was able to discover several of these Cepheids, along with other objects, .and was able to calculate the distance to them from the Milky-Way. Hubble was able to detect nine other new galaxies. Later, in 1925, Hubble came up with a galaxy classification system, which breaks down, or classifies galaxies. Hubble continued to work with galaxies, discovering the…

  • Argumentative Essay About Space Exploration

    The cosmos are a timeless collection of space and stars. It’s our home and it’s our Earth’s home. It holds the key to our survival, the sun. It it both where we came from and where we are going. The universe is all that we have, and human kind has developed the ability to explore it. But the real question is if we should. Some issues should be considered when it comes to space exploration, and those are economics, ethics, and science. These three things are the most important factors to…

  • Essay On Big Bang Theory

    Many theories predicted that after “The Big Bang”, there would have been a remarkable amount of release of radiation. Billions of years later, this radiation would also have been continuing to move away faster from us that the wavelength from this radiation would have been moved from being visible light to the CMB we see today. One of the major pieces of evidence for the big bang theory is that galaxies appear to be moving away from us at speeds that are relational to their distance. This piece…

  • Essay On Dark Matter

    through studying the distribution of gravity within galaxies (Carnegie). Original attempts at studying dark matter referred to dark matter as baryonic, which is a word used to describe baryons, or quark based particles. Quarks make up “normal” subatomic particles, and so when referring to dark matter as baryonic, physicists were assuming that dark matter was made up of protons, electrons, and neutrons, just like all types of known matter, yet that would infer that we would be able to observe…
