Big Dipper over MAGIC Telescope. View of the Ursa Major (Big Dipper) constellation reflected in the multi-mirrored surface of one of a pair of MAGIC (Major Atmospheric Gamma Imaging Cherenkov) telescopes at the Roque de Los Muchachos Observatory, La Palma, Canary Islands. This observatory is situated 2,600 metres above sea level and is home to some of the world's leading research telescopes. The MAGIC telescope is intended to indirectly observe gamma rays by detecting brief flashes of optical light, called Cherenkov light.
