How come we can see the Andromeda galaxy even though its 2.5 million light years away?
Answer: You are correct. Due to the “universal speed limit” for the transport of information in the universe, the speed of light, we see objects in space as they were in the past. The Andromeda galaxy is about 2.5 million light years away, so we see it as it was 2.5 million years ago.
How old is the light from the Andromeda galaxy?

What galaxy is 2.5 million light years away?
the Andromeda galaxy
At approximately 2.5 million light-years away, the Andromeda galaxy, or M31, is our Milky Way’s largest galactic neighbor. The entire galaxy spans 260,000 light-years across – a distance so large, it took 11 different image segments stitched together to produce this view of the galaxy next door.
How far is 2.5 million light years away?
A galaxy can have millions or billions of stars. The nearest large galaxy to us, Andromeda, is 2.5 million light-years away. So, we see Andromeda as it was 2.5 million years in the past. The universe is filled with billions of galaxies, all farther away than this.
How far is 2.5 million light-years away?
Does Andromeda have a sun?
1 trillionAndromeda Galaxy / Stars
Its diameter is around 220,000 light-years and its mass equals the mass of 1,230 billion Suns! There are about one trillion stars in the Andromeda Galaxy. That’s way more than the 200 to 400 billion stars estimated in the Milky Way.
How old is light from Andromeda Galaxy?
Answer Wiki. Yes, light from Andromeda galaxy is 2.5 million year old but it is not too much difficult to say that if it exist now or not.
How long would it take light to reach Andromeda?
Keep in mind that Andromeda is about 2.5 million light years away meaning it would take light 2.5 million years to get there and what we see right now is what andromeda galaxy looked like 2.5 million years in the past, not currently. A lot can happen in 2.5 million years.
How far away is the Andromeda Galaxy?
The Andromeda Galaxy is the most distant object readily visible to the naked eye. It is 2.5 million light years away. The light from it that we see right now is 2.5 million years old. We are therefore seeing the Andromeda Galaxy as it was at a time long before modern humans existed!
Do you know where we live in the Milky Way galaxy?
By now I am sure that you know that we live in an amazing galaxy known as the Milky Way. Some 105,000 light years from side to side, with well over 200 billion stars. We are located only 27,000 light years from the galactic center and go around the center once in some 225 million years – quite amazing stuff!
