| Infrared Space Observatory Iso |
An orbiting infrared telescope launched by the European Space Agency on 17 November 1995. It was equipped to make observations in the waveband between 2.5 and 200 micrometres with a sensitivity much greater than that of its predecessor, the Infrared Astronomical Satellite, IRAS. The instruments on ISO were a camera, an imaging photopolarimeter and two spectrometers to cover shorter and longer wavelengths.
