Hubble Telescope Discovers A 10 Billion Year Old Galaxy

Posted Jul 19, 2012

The Hubble Space Telescope has discovered the oldest known spiral galaxy, which is 10.7 billion years old. By all rights, this galaxy should not exist since it was present in the early universe. This galaxy existed 3 billion years after the Big Bang occurred when galaxies were still being formed.

“The vast majority of old galaxies look like train wrecks,” stated UCLA astronomer Alice E. Shapley. Alice was one of the discoverers of this spiral galaxy. “Our first thought was, why is this one so different, and so beautiful?”

This really old spiral galaxy has prominent spiral arms. One of the reasons why it may exist is because there is a companion dwarf galaxy that appears to be merging with it. Check out the video below:
