Abbrev. for Infrared Space Observatory, an orbiting infrared astronomy observatory launched by the European Space Agency (ESA) on top of an Ariane-4 rocket from Kourou, French Guiana, Nov. 1995. The 2.5-tonne, 5.3-meter-long ISO was the most sensitive infrared satellite of its time, using four detectors cryogenically cooled by liquid helium to capture and study weak infrared radiation from such sources as cold gas and dust clouds and regions of star birth and star death, as well as quasars and remote galaxies. Lying in the focal plane of a telescope with a 60-centimeter mirror, the four detectors were (1) an infrared camera (ISOCAM) covering the range 2.5–17 μm; (2) a photopolarimeter (ISOPHOT) functioning between 2.5 and 240 μm; (3) a shortwave spectrometer covering the 2.4–45 μm band; and (4) a longwave spectrometer operating between 45 and 196.8 μm. These instruments revealed numerous hitherto unknown objects that were ‘visible’ only in infrared light. The satellite operated for about 30 months. Its mission ended in Apr. 1998 when its coolant finally ran out.Collins Dictionary of Astronomy © Market House Books Ltd, 2006
