abstract:The Infrared Space Observatory (ISO) was a space telescope for infrared light designed and operated by the European Space Agency (ESA), in cooperation with ISAS (part of JAXA as of 2003) and NASA. The ISO was designed to study infrared light at wavelengths of 2.
Many Americans recognize the unsurpassed science and inspiration that have come from the Hubble Space Telescope over the past two decades, as well as from its less famous sister satellites like the Chandra X-ray Observatory, the Spitzer Space(Infrared) Telescope and the Fermi gamma-ray observatory.
The US space agency observatory is well suited to picking up the infrared signal expected from cold grains of dust about 10 microns (millionths of a metre) in size.
