Andromeda Galaxy
The largest Galaxy in our local Group, the closest to galaxy to our own. This describes the Andromeda Galaxy. The Andromeda Galaxy is a interesting place in our universe.
The Andromeda Galaxy, a.k.a. Messier 31 (Baidya), is full of just large measurements. An example of this is that it is over 2.3 million light years away (Mclure). It also has an estimated mass of 400 billion solar masses (Baidya). One solar mass being the size of our sun. And on top of that it is littered with 26 black holes (Andromeda Galaxy). The age of the universe is about 13.83 billion years. By comparison The Andromeda galaxy is about 9 billion years old that means that it has been around for about 69% of all time. While earth is only about 4.5 billion years that means …show more content…
Each Star with potential planets orbiting it. It has a diameter is about 260,000 lightyears (Baidya). This is large enough to be seen with the naked eye from Earth. This Galaxy has had a pretty interesting past. For example, at one time it was called the Great Andromeda Nebula (Mclure). Because it looked like a large ball of gas and dust. Also it was once thought to be inside of, our, Milky Way Galaxy (Mclure). Probably due to the relative proximity. And relative is, again, like 2.3 million light years. So the light that the earth is seeing from andromeda is 2.3 million years old. “But it name came from the mythological princess Andromeda” (Andromeda Galaxy), whose myth is much younger than Andromeda’s light. Andromeda has seen our entire existence 2 times over, and has waited 2.3 million years for us to see it, but it has a lot more to go through (Mclure). It is currently moving toward us, really fast. Like 140 kilometer a second (Baidya). That means it could go around the Earth in under 5 minutes at that speed (Baidya). But, isn’t it weird that when our and the Andromeda Galaxy collide the scientific community wants to call it
