Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full Moon. Image released September 25, 2012.

The Universe - Brian Cox Lecture: In this lecture, Brian Cox explains how the Universe was created. What was the Universe like in the first fractions of the first second? How's your quantum mechanics and your understanding of the theory of relativity? It'll be slightly better after this video. Physics made interesting and explained simply.
