2014 Hubble Space Telescope Advent Calendar
25
25
The Hubble Ultra Deep Field. Starting in 2003, the Hubble telescope was pointed toward a relatively empty part of our sky, and in a series of sessions, built up an exposure of just under 1 million seconds, capturing thousands of extremely distant galaxies, some as far away as 13 billion light years. The deeply fascinating part for me has always been the sheer number and scale of galaxies - almost every bit of light you see here is an entire galaxy full of billions of stars each. If we point an instrument at what we thought was a tiny patch of empty space, and come to discover a vastness filled with nearly infinite star systems, it brings to mind a sense of wonder on an incredible scale.
Merry Christmas everyone! I hope you've enjoyed this year's Hubble calendar. And, here's wishing for a peaceful and joyous New Year. (NASA, ESA, and S. Beckwith/STScI and the HUDF Team)
