Max Planck Institute for Extraterrestrial Physics

What Max Planck Institute for Extraterrestrial Physics does

The Max Planck Institute for Extraterrestrial Physics (MPE), established in 1963 as part of the Max Planck Society, is a publicly funded non-profit research institute headquartered in Garching bei München, Germany. MPE conducts space-based and ground-based astrophysics research across four principal divisions: High-Energy Astrophysics (X-ray astronomy), Infrared Astronomy, Optical and Interpretative Astronomy (OPINAS), and the Center for Astrochemical Studies (CAS). The institute develops and operates a portfolio of instruments and space missions including the eROSITA X-ray telescope (which produced the largest-ever X-ray galaxy cluster catalog of 12,247 entries), GRAVITY+ (MPE-led upgrade to ESO's VLTI interferometer achieving first light in November 2025), ROSAT (1990-1999, discovered 125,000 X-ray sources), the Einstein Probe satellite (launched January 2024), LUCI, SPIFFI, and ARGOS adaptive optics systems, plus the pyRate astrochemical modeling code and the Panter X-ray test facility—the only large-scale such facility in Europe. MPE operates approximately 101-250 staff and maintains the unique Panter X-ray calibration facility. Its outputs are not commercial products but open-access scientific data, peer-reviewed publications, and trained researchers disseminated freely to the global scientific community.

MPE is wholly owned and operated by the Max-Planck-Gesellschaft zur Förderung der Wissenschaften e.V., funded primarily through German federal and state government appropriations supplemented by competitive grants from DLR, ESA, EU, and partner agencies. The institute has no shareholders, no external venture backing, and no commercial revenue model. Its primary "customers" are the international astrophysics research community, space agencies (ESA, NASA), and global observatories (ESO, LBT) that consume MPE-developed instruments, data archives, and published findings. MPE is core partner in major international collaborations including ESO instrument consortia (GRAVITY+, 4MOST, MICADO), ESA missions (eROSITA/SRG, Euclid, XMM-Newton, Einstein Probe, future Athena), and NASA collaborations (Chandra, Fermi GBM). The institute achieved its highest public recognition when Director Reinhard Genzel received the 2020 Nobel Prize in Physics for the discovery of a supermassive black hole at the center of the Milky Way, and maintains a pipeline of upcoming missions targeting next-generation capabilities through the 2030s.

Core offering

The Max Planck Institute for Extraterrestrial Physics (MPE) is a non-profit research institute that develops and operates advanced astronomical instrumentation and conducts scientific research in astrophysics. Its portfolio includes space-based X-ray telescopes (eROSITA, ROSAT, Einstein Probe), ground-based adaptive optics and interferometry systems (GRAVITY+, ARGOS, LUCI, SPIFFI), near-infrared and integral field spectrometers, astrochemical modeling software (pyRate), and the Panter X-ray test facility. The institute delivers observational data, catalogs, and trained researchers to the international scientific community through open archives and peer-reviewed publications.

Product overview

The Max Planck Institute for Extraterrestrial Physics (MPE) is a research institute that develops and operates advanced astronomical instruments rather than commercial products. Its portfolio includes ground-based adaptive optics systems (ARGOS, GRAVITY+), near-infrared instruments (LUCI, SPIFFI), X-ray space telescopes (eROSITA, ROSAT, Einstein Probe), and spectroscopic survey instruments (4MOST, KMOS, HETDEX). The institute also develops specialized software tools like the pyRate astrochemical code. MPE leads major international collaborations including the GRAVITY+ interferometry project and participates in future missions like ATHENA and MICADO for the ELT.

Products and services

• eROSITA X-ray Telescope German X-ray telescope for all-sky survey that produced the largest-ever X-ray galaxy cluster catalog (12,247 clusters) with five times the precision of any previous experiment of its kind for measuring matter density and clumpiness in the universe.
• ROSAT X-ray Observatory German-US-UK X-ray observatory (1990-1999) that performed the first all-sky surveys with imaging telescopes, discovering 125,000 X-ray and 479 EUV sources. MPE was responsible for scientific management and focal plane instrumentation and pioneered Zerodur mirror technology with 0.25 nm rms surface roughness.
• GRAVITY+ Interferometry System MPE-led upgrade to the VLTI GRAVITY+ project that uses four laser guide stars to correct atmospheric distortions and enable observation of much fainter objects, deployed at ESO's Very Large Telescope Interferometer in Chile.
• ARGOS Ground Layer Adaptive Optics Advanced Rayleigh-guided Ground Layer Adaptive Optics System for the Large Binocular Telescope (LBT) that uses six pulsed green lasers to generate artificial guide stars and corrects ground layer turbulence over a 4 arcminute field of view, reducing seeing by a factor of two to three.
• LUCI Near-Infrared Instrument Near-infrared instrument for LBT operating in the 0.9-2.5 µm range with a 2048x2048 Hawaii II detector, providing imaging and spectroscopic capabilities in seeing-limited and diffraction-limited modes with multi-object spectroscopy via slit masks.
• SPIFFI Integral Field Spectrometer Fully cryogenic near-infrared integral field spectrometer, the first to provide such capabilities at ESO VLT. Takes 1024 spectra simultaneously in 32x32 pixel format with spectral resolution ~1000-3300 across the 1.1-2.45 µm wavelength range.
• 4MOST Spectroscopic Survey Facility Spectroscopic survey facility for the VISTA telescope, capturing first light in October 2025, designed for large-scale spectroscopic surveys. The facility is led by an MPE-led consortium.
• GRAVITY Interferometry Instrument Interferometry instrument at ESO's VLT that combines light from multiple telescopes for high-resolution observations, including tracking stars orbiting the supermassive black hole at the Galactic Center.
• Einstein Probe X-ray Satellite Satellite launched January 2024 with novel lobster-eye micro-pore optics that has captured over 130 new fast X-ray transients including events that resist classification into any known category of cosmic explosion.
• pyRate Astrochemical Modeling Code Advanced computer modeling code developed at the Center for Astrochemical Studies (CAS) for simulating the evolution of sulfur-bearing molecules in interstellar ice analogues under ultraviolet radiation conditions.
• HETDEX Survey (Hobby-Eberly Telescope Dark Energy Experiment) MPE-participated large-scale astronomical survey that completed the largest survey of the early universe and released its full database publicly in June 2026 to enable scientific, citizen science, and AI research.
• ATHENA Satellite Mission (Future Involvement) Advanced Telescope for High-Energy Astrophysics - future X-ray observatory mission by ESA in which MPE is involved through instrument contributions, including the NewAthena Wide Field Imager.
