The MPG/ESO telescope is a 2.2-metre f/8.0[1] (17.6-metre[2]) ground-based telescope at the European Southern Observatory (ESO) in La Silla, Chile. It was built by Zeiss and has been operating since 1984. It was on indefinite loan to the European Southern Observatory from the Max Planck Institute for Astronomy (MPIA). In October 2013 it was returned to the MPIA. Telescope time is shared between MPIA and MPE observing programmes, while the operation and maintenance of the telescope are ESO's responsibility.[3]

The telescope hosts three instruments: the 67-million-pixel Wide Field Imager[4] with a field of view as large as the full Moon, which has taken many amazing images of celestial objects; GROND, the Gamma-Ray Burst Optical/Near-Infrared Detector, which chases the afterglows of the most powerful explosions in the universe, known as gamma-ray bursts; and the high-resolution spectrograph, FEROS, used to make detailed studies of stars.[5]

In November 2010 it was used to observe HIP 13044, and marked what was thought to be the first time a planetary system in a stellar stream of extragalactic origin had been detected.[6] However, subsequent analysis in 2014 found no evidence for a planet orbiting the star.[7]

Das MPG/ESO-2,2-m-Teleskop (engl. MPG/ESO 2.2 m Telescope) ist ein Spiegelteleskop der ESO in Ritchey-Chrétien-Montierung mit 2,2 Metern Apertur und Teil des La-Silla-Observatoriums in Chile. Gebaut wurde es 1983 von der Firma Zeiss und ist seit 1984 in Betrieb. Es ist eine unbefristete Leihgabe des Max-Planck-Institut für Astronomie (MPIA) mit Sitz in Heidelberg, als Teil der Max-Planck-Gesellschaft (MPG) an die Europäische Südsternwarte ESO. Die Beobachtungszeiten am Teleskop werden zwischen MPIA und ESO aufgeteilt, während Betrieb und Wartung in der Verantwortung der ESO liegen.[1] Das Teleskop befindet sich in einer Höhe von 2335 m.[1]
