A Dictionary of Astronomy | 1997 | Copyright

Infrared Astronomical Satellite (IRAS) A joint US–Dutch–British satellite, launched in 1983January, which made an infrared survey of the sky at wavelengths of 12, 25, 60, and 100 μm. It carried a 0.6-m telescope and an array of detectors cooled by liquid helium. In its 10-month lifetime it surveyed 95 % of the sky, detecting 250 000 infrared sources. Among its discoveries were bands of cometary dust in the Solar System; several new comets and asteroids; infrared cirrus; possible forming planetary systems around certain stars; and a large number of galaxies emitting most of their energy in the infrared, including starburst galaxies.
