Andromeda Galaxy Compare And Contrast

The Andromeda Galaxy, once also known as The Great Nebula in Andromeda, is considered to be one of the largest members of what is called the Local Group. The Andromeda Galaxy, a spiral galaxy closet to our solar system, is now known to be the edge and rim of our Milky Way. Even though the Andromeda Galaxy is bigger than the Milky Way Galaxy, both of these galaxies have many similarities. Astronomers in today’s world base their scientific observations off of the Andromeda Galaxy to make assumptions about the Milky Way. Astronomers have concluded that the Andromeda Galaxy, or M31, is about 2.5 million light- years away, with the entire galaxy spanning 260,000 light-years across. To begin with, being classifies as a spiral galaxy, Andromeda is characterized by arched lanes of stars and many glowing interstellar clouds, which always appears as spiral arms to astronomers. This supports the fact that Andromeda is not an open or globular cluster in what is known as our own Milky Way galaxy. Andromeda is the biggest by volume what astronomers
Andromeda contains a concentrated bulge of matter in the center, surrounded by a disk of gas, dust, and stars. The brightness illuminated from the Andromeda makes it possible to be seen from the naked human eye, also meaning that it is extremely close to earth. Roughly, in about five billion years, the Andromeda and Milky Way galaxy will merge together, which will be deadly to our galaxies. The sun by this time will have swollen up into a red giant and swallowed up the terrestrial planets. The two should settle into a smooth elliptical galaxy, as a normal part of the universe’s evolution. Astronomers have discovered signs of the Andromeda Galaxy previously crashing into other galaxies. The dust surrounding the Andromeda galaxy supports the assumption that it has already swallowed existing galaxies in the
