Ultra Deep Field: Looking into Space, 12 Billion Years Back in Time | Hubble FriendsofNASA.org: 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 e

Round and round we go! This spiral galaxy is called NGC 2985. At about 70 million light-years away, its tightly wound spiral arms widen as they extend outward from the galaxy's bright core. Spiral galaxies like this one tend to run into other galaxies in space, often resulting in galactic mergers. These events scramble up the winding structures of the original galaxies, smoothing and rounding out their shape. Image credit: ESA/Hubble & NASA, L.
