Cosmic Background Explorer

US astronomical satellite launched in 1989 to study cosmic background radiation. It confirmed the Big Bang theory of the universe's creation when its Far Infrared Absolute Spectrophotometer (FIRAS) measured the afterglow of the Big Bang. In 1992 it confirmed that this radiation has a black body spectrum of temperature 2.73 K (−270.4°C/−454.7°F) and revealed ripples in the background radiation believed to mark the first stage in galaxy formation. Its final instrument was turned off on 23 December 1993.
