"Because of the time it takes for light in the distant universe to reach Earth, when we look at, for example, a star a billion light-years away, we're actually seeing what a portion of the cosmos looked like a billion years ago.
So, by combining pictures of various reaches of a small patch of sky, Hubble's new eXtreme Deep Field (XDF) image, released Tuesday, essentially flattens time. Primitive, 13-billion-year-old galaxies—born just 450 million years after the big bang—seem to float side-by-side with closer, more advanced galaxies."

Don't believe in the big bang (like the show tho), but I do believe we are not alone in the universe.
