That's what it looked like 2 million years ago

beautiful image of a galaxy.

So M101 is the largest known galaxy?

[St37One]

not by a long shot

[Andrewp910917]

@joshscott911 No the largest known galaxy is IC1011 (over 6 mln LY in diameter)

For example Milky way has 100 000 LY in diameter)

My mistake, I had that very, very wrong. Take the 20 Billion Light years out, and put 170,000 Light years in. also the milky way is 85,000 light years in diameter. a big mistake on my part.

[Andrewp910917]

@twitchalmighty Milky way has 100 000 LY not 85 000...

@Andrewp910917 What does LY mean good sir? I'd like to learn it.

@Andrewp910917 What does LY mean good sir? I'd like to learn it. Nevermind l0l - Light years. How did I forget that fail :(

Compared to M101, the Milky Way Galaxy would be practically the size of an amoeba. The Milky Way is 100,000 light years in diameter, where as M101's diameter is closer to 20 Billion light years. the Solar system would be about the size of a hydrogen atom, and the Earth would be close to the size of a Photon. But that is all from theory, and constant thought.

Very great job. Their are more than 500 billion galaxies in the known universe.

[MrCanuck]

Just as many as in each one of my nuts.

[muffles12]

that right soon it will become 600 billion galaxy in our dern universe

[alicrysis]

very nice galaxy
