- The Infrared Astronomy Satellite (IRAS)was a joint scientific project sponsored by the United Kingdom, the United States, and the Netherlands. IRAS was launched in January of 1983 and ended its mission ten months later. IRAS' mission was to map the entire sky at infrared wavelengths. It was equipped with a special infrared telescope to scan the sky. IRAS was the first satellite to discover a comet. The comet IRAS-Araki-Alcock was named for the probe and two co-discovering astronomers. During its lifespan, IRAS observed 20,000 galaxies, 130,000 stars and 90,000 other space objects and star clusters. IRAS detectors found a disk of dusty material and fine rock around the star Vega which may be an early stage in the formation of a new solar system. IRAS' most famous discovery was that of a new type of galaxy, a starburst galaxy. In starburst galaxies, new stars are forming more rapidly than in other types of galaxies.

| Abstract from DBPedia | The Infrared Astronomical Satellite (Dutch: Infrarood Astronomische Satelliet) (IRAS) was the first space telescope to perform a survey of the entire night sky at infrared wavelengths. Launched on 25 January 1983, its mission lasted ten months. The telescope was a joint project of the United States (NASA), the Netherlands (NIVR), and the United Kingdom (SERC). Over 250,000 infrared sources were observed at 12, 25, 60, and 100 micrometer wavelengths. Support for the processing and analysis of data from IRAS was contributed from the Infrared Processing and Analysis Center at the California Institute of Technology. Currently, the Infrared Science Archive at IPAC holds the IRAS archive. The success of IRAS led to interest in the 1985 Infrared Telescope (IRT) mission on the Space Shuttle, and the planned Shuttle Infrared Telescope Facility which eventually transformed into the Space Infrared Telescope Facility, SIRTF, which in turn was developed into the Spitzer Space Telescope, launched in 2003. The success of early infrared space astronomy led to further missions, such as the Infrared Space Observatory (1990s) and the Hubble Space Telescope's NICMOS instrument.IRAS（Infrared Astronomical Satellite、アイラス）は、アメリカのNASA、オランダのNIVR、イギリスのが共同で計画した赤外線天文衛星である。1983年1月25日に打ち上げられ、10ヶ月間で25万回もの観測を行った。 一般に赤外線天文衛星では観測装置を絶対零度近くまで冷却する必要がある。IRASの場合、720リットルの液体ヘリウムを冷却剤として搭載し、これが蒸発することで観測装置を1.6Kに保っていた。しかし1983年11月に冷却剤が尽きたため、運用終了した。 (Source: http://dbpedia.org/resource/IRAS) |
