New Cosmological Insights from the South Pole Telescope

Cosmic Microwave Background

This image displays a portion of the South Pole Telescope survey of the cosmic microwave background (CMB) - the radiant light left over from the Big Bang. Points of light mark quasars and gravitationally lensed galaxies. The variations in the image are minute fluctuations in the intensity of the CMB. The fluctuations are caused by differences in the distribution of matter in the early universe at a time only 400,000 years after the Big Bang. The image is effectively a "baby picture" of the universe.

SPT Collaboration

South Pole Telescope

The South Pole Telescope is a 10-meter-diameter telescope located at the Amundsen-Scott South Pole Station, Antarctica. This cold, dry location facilitates observations of the faint cosmic microwave background.
