Wilkinson Microwave Anisotropy Probe: WMAP

The Wilkinson Microwave Anisotropy Probe is NASA's current mission designed to study the variations in the primordial background radiation (the Three Degree Background Radiation, or Cosmic Micowave Background) discovered by Penzias and Wilson in 1965. WMAP was launched in the spring of 2001 and its results were announced in 2003.

WMAP has allowed us to set very precise limits on the values of the most important cosmological parameters.

WMAP was originally called MAP, but was renamed after the death of one of its team leaders, David Wilkinson of Princeton University. Dave was a brilliant cosmologist and a very nice person, and he is sorely missed.
