Baryons at the Edge: SRG/eROSITA Survey Detects “Missing” Cosmic Gas at the Outskirts of Galaxy Clusters

A team of researchers at MPE has used data from the eROSITA sky survey to discover hot gas extending far beyond the known boundaries of galaxy clusters. This discovery provides new insights into the growth of these cosmic structures and helps solve the mystery of the “missing baryons.”
A scientific collage of 112 square individual images from the Euclid space telescope, arranged in a six-by-six grid on a black background. Each square shows a different strong gravitational lens in the distant universe. At the center of nearly every image is a bright, mostly yellowish-white foreground galaxy. Surrounding these central galaxies, the effects of spacetime curvature are clearly visible: the light from even more distant background galaxies appears as blue arcs of light, circularly curved arcs, filamentary structures, or nearly closed rings—so-called Einstein rings. Some images also show point-like multiple images of the same background galaxy, arranged symmetrically around the center. The details are very sharp, and in the background of each square, additional tiny, distant galaxies and stars are visible as points of light.

10,000 Euclid lenses wanted: MPE call for Space Warps

The Max Planck Institute for Extraterrestrial Physics (MPE) in Garching is inviting the public to take part in the ‘Space Warps’ citizen science project on the Zooniverse platform. Volunteers are asked to identify strong gravitational lenses in as yet unpublished images from ESA’s Euclid space telescope. Scientists expect over 10,000 new candidates – more than in 50 years of all previous discoveries combined.

SRG/eROSITA reveals how our Solar System modifies the appearance of the X-ray sky
Two exoplanets near a star and a graph. To confirm that this new object is indeed a planet and not an extended clump of material within the disc, astronomers observed it with the GRAVITY+ instrument at the VLT Interferometer (VLTI). The VLTI combines the light of several telescopes and is therefore sensitive to very small details. Using GRAVITY+, the team confirmed that that the new object is a point-like source and not an extended cloud within the disc.

Rare Discovery of Two Protoplanets
 

Using the GRAVITY instrument on the ESO’s VLT Interferometer, astronomers have confirmed the existence of the protoplanet WISPIT 2c. This new discovery offers rare insights into planet formation and shows that planetary systems can form in parallel.

Dawn of a New Era of Interferometry with GRAVITY+

Beginning of November 2025, four lasers were fired into the sky above ESO’s Paranal Observatory in Chile, each creating an artificial star to help astronomers measure and correct atmospheric blur. This impressive launch, one from each 8-meter telescope, marks a key milestone of the GRAVITY+ project, led by MPE, significantly enhancing the VLTI’s ability to observe fainter objects and cover more of the southern sky.
