The superconducting camera, SCAM, is an ultra-fast photon-counting camera, developed by the ESA. It is cooled to just 0.3 K (three-tenths of a degree above absolute zero). This enables its sensitive electronic detectors, known as superconducting tunnel detectors, to register almost every photon of light that falls into it.
