IRAS
The Infrared Astronomical Satellite (IRAS) was the first-ever space-based
observatory to perform a
survey of the entire
sky at
infrared wavelengths.Launched on
January 25,
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).IRAS was the first observatory to perform an all-sky survey at infrared wavelenghts. It mapped 96% of the sky four times, at 12, 25, 60 and 100 micrometre wavelengths, with resolutions ranging from 0.5' at 12 micrometers to 2' at 100 micrometers. It discovered about 350,000 sources, many of which are still awaiting identification. About 75,000 of those are believed to be
starburst galaxies, still enduring their
star-formation stage. Many other sources are normal stars with disks of dust around them, possibly the early stage of a
planetary system formation. New discoveries included a dust disk around
Vega and the first images of the
Milky Way Galaxy's core.
