![]() ![]() ![]() In 2022 alone, users submitted over 237,000 queries for IRAS data from IRSA. ![]() The IRAS dataset resides at the NASA Infrared Science Archive (IRSA) at IPAC on the Caltech campus. The Astrophysics Data System (ADS) lists roughly 3,500 peer-reviewed papers published from 2018 through 2022 that cite IRAS data or targets-an average of more than 500 papers per year. Those sources were characterized as normal stars, newly formed stars still embedded in their natal cloud of gas and dust, stars with extreme properties, normal galaxies and ultra-luminous galaxies emitting most of their energy in the infrared, comets, and asteroids.įour decades later, the mission's catalogs continue to be regularly accessed by researchers. IRAS’s infrared wavelengths gave it the ability to peer deep into clouds of gas and dust obscured at visible wavelengths, to study extremely cold objects, and to study objects in the distant universe. The Explorer-series satellite’s 62 individual detectors scanned more than 96% of the sky over 10 months, capturing about 350,000 infrared sources and producing a dramatic new skymap of our Milky Way galaxy. Launched 40 years ago today on January 25, 1983, IRAS was the first space telescope to make a comprehensive, reliable survey of the sky at infrared wavelengths of light. When the first long-awaited images from NASA's James Webb Space Telescope (JWST) were released in 2022, inspiring the next generation of astronomers and astronomy enthusiasts, few probably understood how much those breathtaking images were made possible by a little space satellite called the Infrared Astronomical Satellite (IRAS).
