SCUBA-2 on the JCMT
SCUBA-2 mounted on the James Clerk Maxwell Telescope. The instrument weighs 4.5 tonnes and is 3 m high. The massive blue box contains the camera and keeps it cold at only 0.1 degrees C above absolute zero (-273 degrees C). Submillimetre light from the telescope enters through a small window on the left-hand side (behind the white bars) and is directed onto the two sets of detectors. Credit: Joint Astronomy Centre
