  • November, 2020: SPT-3G has completed its 2020 winter observing season! The 2020 observing season was fortunately unaffected by Covid, with SPT-3G achieving record sensitivity and efficiency! Congrats to winter-overs Allen Foster and Geoff Chen for a fantastic season!

  • March 30, 2020: SPT-3G begins its 2020 winter observing season! SPT-3G is continuing to observe our 1500 square degree survey field, which overlaps with the BICEP Array survey, as part of the South Pole Observatory (SPO)!

  • December, 2019: The SPT-3G experiment has completed its 2019 winter observing season! Winter-overs Doug Howe and David Riebel have left Pole after finishing a successful 2019 austral-winter observing season at the South Pole! A small austral-summer crew relived them, to complete observing the 1500 sq. deg. SPT-3G survey patch for another month, before beginning annual maintenance on the telescope and camera.

  • September 5, 2019: Congratulations to the Event Horizon Telescope (EHT) collaboration for being awarded the 2020 Breakthrough Prize in Fundamental Physics. The citation reads: "For the first image of a supermassive black hole, taken by means of an Earth-sized alliance of telescopes.” The $3 million prize will be shared equally among the 347 co-authors, including SPT collaboration members Brad Benson, John Carlstrom, Tom Crawford, Jason Henning, Ryan Keisler, Erik Leitch, Daniel Michalik, Andrew Nadolski, Steve Padin, and Sasha Rahlin. The 10 meter South Pole Telescope (SPT) is a critical component of the network of telescopes that make up the EHT.

  • 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 1500 sq. degrees.
