The Andromeda Galaxy - It is 2 million light years away from us...so what we see now is how it appeared 2 million years ago. It will collide with our Milky Way in 2 billions years from now - the two galaxies are heading towards each other at a rate of 430 km/hr! A billion years from now Andromeda will loom as a spectacular site, eventually swelling to fill half of the night sky.
