The Andromeda Galaxy is roughly 100,000 light years in diameter.
It has the same things the other galaxies have i.e. stars planets etc . It's just that it is very big . Comments : I think the answer may be that Andromeda gives out light that is blue shifted instead of the red shift for most galaxies. So the answer is " a light spectrum that's blue shifted".
The nearest "big" galaxy after the Milky Way is called the Andromeda galaxy, because with our line of sight from earth, it appears to be in the the constellation Andromeda. It is 2.5 million light years away.
The black hole in the Andromeda galaxy is estimated to be around 140 million times more massive than our sun. It is located at the center of the galaxy and plays a crucial role in shaping its evolution and dynamics.
Ah, what a great question! The little galaxy right next door to us is called the Andromeda galaxy. It's like our neighbor in this big galactic community we all live in. Just imagine all the stunning colors our universe shares with Andromeda!
You simply can't - it is too far away, at least for current technology. However, the Andromeda Galaxy is a galaxy just like any other one - I see no big difference between being there, or being here in our own galaxy.
It's difficult to define a galaxies size, as there is no real cut off point. From estimations, the Andromeda is about twice as large as the Milky Way.
The Andromeda Galaxy is believed to be created around the same time as the Milky Way Galaxy. This would put it's age close to just after the "big bang" at around 13.2 billion years.
About 17 billion years after the big bang , when it will merge with our own galaxy - the Milky Way. After that, a new name will have to be thought of, if anyone is still around. currently andromeda galaxy is 2.5 million light years away and moving toward us with a speed of 120 km per second
Ah, the galaxy closest to us is called the Andromeda Galaxy, isn't that a lovely name? Just imagine the beauty of two galaxies dancing in the stars, sharing their light and secrets with one another. It's a magical sight to behold, my friend.
The Andromeda Galaxy or M31 has been estimated to be 220,000 light years across. Our Galaxy, The Milky Way, is about 100,000 light years across.See link for more information.The latest estimates for the diameter is about 43,000 ly across.This is based on a 3.18 degree angle in the sky and a distance of 2.54 Mly.A big caveat here that this is only the visible part of the galaxy. Since a galaxy must be made up of a substantial amount of dark matter the true size of the galaxy cant be determined at the moment.
Currently, about 2.5 million years. The "Andromeda galaxy" is more properly called "M31 in Andromeda". Charles Messier was a 17th century comet hunter. To keep from getting confused between newly-discovered comets and "smudgy things in the sky that just LOOKED like comets", Messier created a catalog of all the comet-looking things in the sky that weren't comets. The "Great Andromeda Nebula" was the 31st item in Messier's list. M31 is a galaxy very similar to our own, with about a trillion stars. We now know that the Andromeda galaxy and our own Milky Way will probably collide in about 4 billion years.
Most of them. except for Andromeda galaxy which is coming towards us - our Milky Way galaxy and they both will collide in 3-4 billion years(Repetition of ''Big Bang'')
