Mauna Kea, Hawaii
The telescope’s Submillimeter Common-User Bolometer Array 2 (SCUBA-2) camera images objects ranging from comets in the Earth's solar system to galaxies at the far ends of the universe. The camera can carry out large-scale surveys of the sky to unprecedented depths. Submillimeter wavelengths of light contain a lot of information about the universe; for instance, light from stars inside young galaxies is trapped in dust clouds and re-emitted in this band.
The SCUBA-2 camera is made of more than 10,000 NIST sensors. The camera is a collaboration of the UK Astronomy Technology Centre, NIST and four British and Canadian universities.
SCUBA-2 has imaged thousands of submillimeter galaxies, which are used to understand galaxy evolution and cosmic star formation.
SCUBA-2 maps the sky 100-150 times faster than its predecessor camera.
