The Hubble Space Telescope just calculated the distance to the most far-out galaxy ever measured, providing scientists with a look deep into the history of the universe.
The far-away galaxy, named GN-z11, existed a mere 400 million years after the Big Bang, or about 13.3 billion years ago.
Because the light from such a distant galaxy must travel huge distances to reach Earth, scientists are seeing the galaxy as it looked over 13 billion years ago.

"We've taken a major step back in time, beyond what we'd ever expected to be able to do with Hubble," Pascal Oesch, an astronomer at Yale University and lead author of the research paper announcing the new measurement, said in a statement from the Hubble European Space Agency Information Centre in Germany.
