If you dont understand anything about astronomy allow me to explain.
Stars you see in the sky are mostly suns like our sun.
Its an accepted fact that the vast majority of these suns will have a dozen or so planets circling them. Most likely a good number have some form of life.
But if you look further then our galaxy (milky way), you'll see even more stars which are galaxies.
These galaxies contain billions of stars (or suns), which in turn have planets circling them. There a billions or perhaps trillions of these galaxies spread out throughout space.
Until recently we didnt know how far we could peer out into space, that was untill Hubble did whats called the 'Ultra Deep Field'.
It looked as far as it could and this is the result (its absolutely fascinating and mind boggling the sheer number of galaxies in one tiny section of the universe).
BTW, ignore the Numa Numa guy midway through.
