Ultra Deep Field: Looking Out into Space, Looking Back into Time

Ultra Deep Field: Looking Out into Space, Looking Back into Time

This six-minute visual exploration of the Hubble Ultra Deep Field showcases the characteristics and contents of this landmark observation, as well as its four-dimensional nature across both space and time. In particular, galaxies are seen to more than 12 billion light-years away (12 billion years ago), allowing astronomers to trace the development of galaxies across cosmic time.

A deep field is a long exposure on a small field of view to observe the faintest objects possible. The Ultra Deep Field represents the deepest visible light observation of the universe (deeper views are extensions or subsets of this 2004 image). Containing about 10,000 sources, the Ultra Deep Field provides a statistical sample of galaxies across the universe.
