COBE
The 2006 prize was won by [[John C. Mather]] and [[George F. Smoot]] (leaders of the [[Cosmic Background Explorer]] (COBE) satellite experiment) for "discovery of the blackbody form and [[anisotropy]] of the [[cosmic microwave background radiation]] (CMBR)." However, in July 1983 an experiment launched aboard the [[Prognoz 9]] satellite, studied CMBR via a single frequency. In January 1992, Andrei A. Brukhanov presented a seminar at [[Sternberg Astronomical Institute]] in Moscow, where he first reported on the discovery.
