The aurora australis and the Milky Way fill the long winter night sky over the South Pole Telescope. Dr. John Carlstrom, University of Chicago, leads the team researching the cosmic microwave background (CMB) radiation at the South Pole. Their goal is to detect all galaxy clusters in this region of the sky through the distortion they can see on the CMB. The South Pole is an ideal location for telescopes with months of darkness, a constant view of the same sky, and extremely low humidity in the air. On the lower left corner of this photo, Jupiter is visible as a bright spot.
