Big Dipper and MAGIC Telescope

Stars of the constellation Ursa Major (the Big bear) form the familiar dipper-like asterism in the northern sky as photographed from the Roque de los Muchachos Observatory on the Canary island of La Palma. The starry night sky is reflected from one of a pair of 17 meter diameter, multi-mirrored MAGIC telescopes. The MAGIC (Major Atmospheric Gamma Imaging Cherenkov) telescope is intended to observe gamma rays indirectly by detecting brief flashes of optical light, called Cherenkov light.
