This video begins with a view of the thousands of galaxies in the Hubble Ultra Deep Field and slowly zooms out to reveal the larger Hubble Legacy Field, containing 265,000 galaxies. The Hubble Legacy Field combines 16 years’ worth of Hubble observations into a single image that represents the largest and most comprehensive "history book" of galaxies ever made. They stretch back through 13.3 billion years of time to just 500 million years after the universe's birth in the big bang.
