(Background Imaging of Cosmic Extragalactic Polarization)
(surveys to measure the polarization of the CMB)

BICEP2 is a survey of CMB polarization at the South Pole Station. An earlier survey was called BICEP. The terms also refer to the survey-specific telescopes used.

It was announced in early 2014 that BICEP2 detected B-mode (polarization modes) gravitational waves from the early universe, offering evidence of inflation, but further analysis concluded that dust within the Milky Way could produce such a signal, so the observation was inconclusive.
