Project Profile

The South Pole Telescope (SPT) is a stunning achievement in humanity’s study of the cosmos. Equipped with a 10-meter diameter microwave/millimeter/submillimeter telescope, the team behind the SPT hope to answer some of the most important questions that scientists have ever asked: What is the origin of the universe, what is it made of, and what is it’s final fate? 

Located at the NSF Amundsen-Scott South Pole Station, the SPT is at the optimal operational site for millimeter wave survey observations due to its stable, dry atmosphere. This unique location allows the SPT to play a critical role in assisting the Event Horizon Telescope (EHT) in its pursuit to image the event horizon around the black hole at the center of our own Milky Way Galaxy. 

Part of the Center for AstroPhysical Surveys at NCSA, the SPT has been observing cosmic background microwave radiation since 2007.
