The MPG/ESO telescope is a 2.2-m 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 is on indefinite loan to the European Southern Observatory from the Max Planck Institute for Astronomy. Telescope time is shared between MPG and ESO observing programmes, while the operation and maintenance of the telescope are ESO’s responsibility.[4]

The telescope hosts three instruments: the 67-million pixel Wide Field Imager 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 discover HIP 13044 b, marking the first time a planetary system in a stellar stream of extragalactic origin has been detected.[6]
