View of the night sky 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. Sirius, the brightest star in the night sky, located in the constellation Canis Major, appear in the sky. Right at the mountain is the M41 Star Cluster. Higher on the peak is the Nordic Optical Telescope (NOT). This observatory is situated 2,400 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.
