The South Pole Telescope (or SPT) is a telescope deployed at the South Pole that is designed to study the Cosmic Microwave background. Constructed between November 2006 and February 2007, the SPT is the largest telescope ever deployed at the South Pole. This telescope provides astronomers a powerful new tool to explore dark energy, the mysterious phenomena that may be causing the universe to accelerate. We invite you to explore these pages to share in our experiences during the design, construction, and (currently) operation of this powerful telescope.

  NSF The South Pole Telescope is funded through the National Science Foundation Office of Polar Programs.
