Island Universes

This is Abel 779 -- a galaxy cluster of dozens of "Island Universes" in the Lynx constellation. The bright fuzzy galaxy in the center is NGC 2832.

The concept of other galaxies, like our Milky Way, is relatively new. In fact, until 1929 astronomers thought these faint fuzzy objects were nebulae located right here in our own Milky Way. But Hubble (the man, not the telescope) proved that the stars in the Andromeda "nebula" were actually FAR outside of our galaxy -- Andromeda was another galaxy, like ours!

Until this time, it was thought the Milky Way WAS the universe. Suddenly, overnight, the universe grew to immense proportions and other galaxies ("Island Universes") began popping up everywhere. Our Milky Way went from being the universe to being just one tiny minor part of a much bigger picture!
