All the great islands of stars got their start in the first billion years after the beginning of time, the Big Bang. Every deep picture of the sky reveals thousands of these galaxies, each made up of billions of stars like the Sun. Modern instruments like the Hubble Space Telescope have made it possible to look back to a time when the universe looked very different that it does today. Dr. Stephen Beckwith of the University of California discusses some of the deepest images of the universe ever taken and shares recent discoveries about the early days of the cosmos.
