October 30, 2017: Summer team begins arriving at the South Pole



October 10, 2008: Galaxy clusters discovered with the South Pole Telescope. Images of the first four galaxy clusters detected in the South Pole Telescope survey. Images are postage-stamp cutouts of larger maps in each of the three SPT observing bands (centered at 95, 150, and 225 GHz). Sunyaev-Zel'dovich effect intensity decrements in the direction of the cluster are clear in the unfiltered 150 GHz image and in the filtered 95 and 150 GHz images. No decrement (or increment) is seen in the 225 GHz image, as is expected for the SZ effect.

November, 2017: SPT-3G camera upgrade begins.

Scientists working on the South Pole Telescope (SPT) project have made the long-journey to Antarctica to begin work on the SPT-3G camera. The goal for this summer season is to bring the SPT-3G camera up to full sensitivity following its initial installation in Jan 2017. The upgraded camera will have more than 10x more detectors than its predecessor, SPTpol, and will be used to make an ultra-sensitive map of CMB polarization across 2500 sq. degrees.

  The South Pole Telescope is funded through the National Science Foundation and the Department of Energy Office of Science. NSF DOE
