"We find them smaller and fainter, in constantly increasing numbers, and we know that we are reaching into space, farther and farther, until, with the faintest nebulae that can be detected with the greatest telescopes, we arrive at the frontier of the known universe." -Edwin Powell Hubble

We are billion year old carbon,
And we got to get ourselves back to the garden." -Crosby, Stills, Nash & Young
