[center][size=12]Ok, so how big is our planet Earth?

Haven't you learned anything?

Haven't you learned anything?  Stars don't produce warmth!  Farting cows, SUVs, and incadescent light bulbs do!    ;)

Thats why I try to eat as many cows as I can.

Wanna see big?  ;D

*Sniff* Whose cooking?  

It really puts you in your place to see things like that...

and we think our solar flares are bad....

If there is ANYTHING larger than my ego in this galaxy I want it caught and shot immediately!

Only Fozzer's solar flares, and he hasn't worn those outside in ages  ;)  ;D

Speaking of perspective: all of those objects are but mere specks inside our galaxy, which is about 100,00 light-years across, and just packed with stars... billions of 'em!

And the nearest galaxy, M31, one of the largest if not  brightest distant objects in the night sky, is itself about 2.5 million light-years away...  in a very dark place, you can sometimes make out M31 with the naked eye... binocs work even better. If you ever see it, consider that that light has taken over 2 million years to reach your eye...!!!

I thought Andromeda was the nearest galaxy. By the way, Andromeda is destined to collide with the Milky Way in about 3 billion years from now.

M31 is the Andromeda galaxy- it's in the constellation of Andromeda.
But it's called M31 because it's #31 on Charles Messier's list of nebulae and star clusters he compiled in
the 18th century. He was a comet hunter who decided to catalogue non-transient objects in order to help himself and others avoid wasting time in their hunt for comets. Did it all with a rather crude telescope, too... some of them are pretty hard to find even with a good telescope, unless you have the coordinates.
