^ Maybe the galaxy was sucked up in to a black hole, a million years ago. ;)

There is a huge supermassive black hole at Andromeda's core, but its influence beyond the core itself is minimal - just like with the one at the core of the Milky Way. Most of their long distance influence occurs when the galaxy is formed and shottly after.

and to think, in about ~4 billion years we (as in the Milky Way) will crash into that. The universe is a beautiful and dangerous place.

What NASA thinks the Andromeda / Milky Way collision will look like from Earth. Remember that we are in the outskirts of the Milky Way giving us a ringside seat.

A collision of the central regions would resilt in star / neutron star / black hole collisions in areas of high density, star formation where gas clouds collide, an increase in supernovae and black holes gobbling up anything that comes near, etc.

A real freakin' fireworks show.

Thats cool :) isnt it amazing how far we can see these days, and I wonder what it looks like now, that image is what Andromeda looked like 2.5 million years ago :)


2.5 million light-years denotes distance and not time :)

light years are measure by the distance that the speed of light per year so since andromeda is 2.5 million light years away we are seeing the light that the galaxy showed off 2.5 millions years ago
