ISO

Overview: The Infrared Space Observatory (ISO) was launched by ESA in late 1995 and operated for 30 months before the cryogen was exhausted. ISO carried a cooled 60-cm telescope and four science instruments which conducted nearly 30,000 observations at wavelengths between 2.5 and 240 microns. Subsequent processing and analysis of data continued through 2001. ISO has left a rich treasure of scientific results, ranging from the Solar System to galaxies in the distant Universe. ISO data are available through IRSA for archival research by the entire science community.
