Andromeda and milky way comparison essay.
Essays: Comparison of the Milky Way and M31. Globular Clusters One measure of a galaxy’s relative size and prominence is the number, size, and luminosity of its globular clusters. The number of the globular clusters in the Milky Way is particularly hard to estimate, since much of the Milky Way is hidden from our view by dust and gas.
The Andromeda galaxy is the closest full size galaxy to the Milky Way. The Andromeda Galaxy is about four times bigger than the moon in the sky. Andromeda contains around one trillion stars. The Andromeda Galaxy is also the only galaxy noticeable to the naked eye in the Northern Hemisphere.
A comparison of some of the basic properties of M31 and the Milky Way indicates that in almost every respect M31 is larger than the Galaxy. It is more luminous, redder, more massive, and of earlier Hubble type. A detailed comparison of the spiral structure, based on optical tracers, for comparable areas in the outer parts of each galaxy shows differences in the arm spacings, in density.
Andromeda closely resembles the Milky Way in shape (spiral), structure, and distribution of chemical elements. But that is where their similarities end, for Andromeda dwarfs the Milky Way and contains around twice as many stars. This galaxy is set among the stars of the constellation of Andromeda, the tiny misty blur that astronomers know by.
The Milky Way Galaxy essaysOne of the most intriguing parts of the universe is our knowledge of the Milky Way. The hazy band of white light that one can often see in the night sky has been proven to be the home of our Solar System. There are so many different aspects that make the Milky Way so incr.
The Milky Way and its nearest galactic neighbor, Andromeda, don’t resemble each other much now, but a new study suggests the two shared similar beginnings and evolved in similar ways, at least.
A comparison of M31 and the Milky Way in molecular gas. Bulletin of the American Astronomical Society 1997; 29: 1345. Dame, T.M. Large-scale molecular surveys of the Galaxy and M31.
