'''MAGIC''' ('''Major Atmospheric Gamma Imaging Cherenkov Telescopes''', later renamed to '''MAGIC [[Florian Goebel]] Telescopes''') is a system of two [[IACT|Imaging Atmospheric Cherenkov telescope]]s situated at the [[Roque de los Muchachos Observatory]] on [[La Palma]], one of the [[Canary Islands]], at about 2200 m above sea level. MAGIC detects particle showers released by [[gamma rays]], using the [[Cherenkov radiation]], i.e., faint
light radiated by the charged particles in the showers. With a diameter of 17 meters for the reflecting surface, it was the largest in the world before the construction of [[High Energy Stereoscopic System|H.E.S.S. II]].

The first telescope was built in 2004 and operated for five years in standalone mode. A second MAGIC telescope (MAGIC-II), at a distance of 85 m from the first one, started taking data in July 2009. Together they integrate the MAGIC telescope stereoscopic system.<ref>"Technical status of the MAGIC telescopes", MAGIC collaboration, Proc.

MAGIC is sensitive to cosmic [[gamma ray]]s with [[photon energy|photon energies]] between 50&nbsp;[[GeV]] (later lowered to 25&nbsp;GeV) and 30&nbsp;[[TeV]] due to its large mirror; other ground-based gamma-ray telescopes typically observe gamma energies above 200–300&nbsp;GeV. [[Gamma-ray astronomy]] also utilizes satellite-based detectors, which can detect gamma-rays in the energy range from keV up to several GeV.
