United Kingdom Infrared Telescope
The United Kingdom Infrared Telescope (UKIRT) is a 3.8-m telescope that is the world's largest dedicated solely to infrared astronomy. It opened in 1979, is sited near the summit of Mauna Kea, Hawaii, at an altitude of 4,194 m, and operates at wavelengths between 1 and 30 microns. In 2002, it was equipped with a revolutionary new spectrometer, the UKIRT Imaging Spectrometer (UIST), that can effectively slice any celestial object into sections and so produce a three-dimensional view of the conditions throughout entire galaxies, for example, in a single observation. UKIRT is owned by the UK Particle Physics and Astronomy Research Council and operated along with the James Clerk Maxwell Telescope by the staff of the Joint Astronomy Centre.
