Caption

Photomultiplier tube (PMT) in the Borexino neutrino detector. Neutrinos are elementary particles produced by nuclear reactions in stars and in supernova explosions. PMTs line the interior of a stainless steel sphere. They detect the flash of light when a neutrino hits the liquid core of the detector (not seen). The aim of the Borexino detector is to measure neutrino flux from the Sun. Photographed at the Gran Sasso Laboratories, Abruzzo, Italy. The laboratories are located 1400 metres underground and are accessed from a 10 kilometre long road tunnel. The rock overlay shields the laboratories from cosmic rays.
