Caption
The night sky dances with auroras over Dark Sector Laboratory at the Amundsen-Scott South Pole Station at the geographic South Pole. On the very far right, inside the silver ground shield, is BICEP3, which has been observing since 2016. The BICEP/Keck collaboration operates a series of small aperture telescopes including BICEP3 that are targeted at the search for signatures of inflationary gravitational waves.
