Staring into the cosmos. The Hubble Ultra Deep Field is the deepest image ever taken of the universe in visible light. The bright and sparkling spots are not stars but galaxies. The nearest one is about one billion light-years away, and since one light-year is the distance light travels in a year, the view is of that one galaxy as it appeared a billion years ago.

And It Almost Didn't Happen!
