* ANDROMEDA*

Posted by Louisa at 3:00 AM


I was watching the television series the other day. The title was ANDROMEDA. The name itself fascinated me, and so I decide to Google it. I never believed what I found.. Andromeda is a galaxy, just like our Milky Way, where The Sun System located. I’m wondering whether Andromeda sustains any live in there.

Andromeda, also known as Messier 31, is the nearest spiral galaxy to our own, the Milky Way. It is visible as a faint smudge on a moonless night, it is one of the farthest objects visible to the naked eye, and can be seen even from urban areas with binoculars. It gets its name from the area of the sky in which it appears.

Andromeda was named after the mythological princess Andromeda. Andromeda is the largest galaxy of the Local Group, which consists of the Andromeda Galaxy, the Milky Way Galaxy, the Triangulum Galaxy, and about 30 other smaller galaxies.

The Andromeda Galaxy is approaching the Sun at about 100 to 140 kilometres per second, so it is one of the few blue shifted galaxies. The Andromeda Galaxy and the Milky Way are thus expected to collide in perhaps 4.5 billion years, although the details are uncertain since Andromeda's tangential velocity with respect to the Milky Way is only known to within about a factor of two.

I really hope scientists will work something out as we don't collide. On the next post, i will introduce The Milky Way to you..
