  • The sun sets behind BICEP2 (in the foreground) and the South Pole Telescope (in the background).
  • The BICEP2 telescope's focal plane consists of 512 superconducting microwave detectors, developed and produced at NASA's Jet Propulsion Laboratory.
  • The tiny temperature fluctuations of the cosmic microwave background (shown here as color) trace primordial density fluctuations in the early universe that seed the later growth of galaxies.
  • Gravitational waves from inflation generate a faint but distinctive twisting pattern in the polarization of the cosmic microwave background, known as a 'curl' or B-mode pattern.
  • Graduate student Justus Brevik tests the BICEP2 readout electronics.
