On scales of hundreds of millions of light-years, galaxies are distributed along a vast network of matter filaments known as the cosmic web. While it was already known that galaxies located near cosmic filaments are, on average, more massive and more frequently "quenched" in the present-day...
Rodrigo Ibata, Research Director at CNRS at the Strasbourg Observatory (Unistra/CNRS), receives the 2026 Kavli Prize in Astrophysics alongside Amina Helmi (University of Groningen) and Vasily Belokurov (University of Cambridge). Recognized for his study of debris from ancient galaxies, which...
An international team of researchers, led by Dr Paolo Bianchini (CNRS, Strasbourg Astronomical Observatory), has achieved a major breakthrough in our understanding of globular clusters—stellar systems almost as old as the Universe itself. Using state-of-the-art numerical simulations, the...
A team of astronomers led by Lucie Correia just brought a new perspective on galaxies in the millimeter–centimeter range with archival data, in a recent paper published in Astronomy and Astrophysics. The team has achieved a detailed characterization of how nearby galaxies emit light in the...

An international team of astronomers using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) has identified the origin of X-rays in a supermassive black hole’s jet, answering a question that has been unresolved since the earliest days of X-ray astronomy. Their findings are described in papers...
Aladin Lite is the recipient of the 2025 Open Science Award for Free Research Software in the Community category ! A well deserved recognition, beyond the astronomical community, of the Aladin team. More information : List of recipients for the 2025 awards on the Ministry...
The astronomical observatory of Strasbourg (ObAS), in conjunction with the Interdisciplinary Thematic Institute IRMIA++ (Research in Mathematics, Interactions & Applications) of the Strasbourg University, is opening a post-doctoral fellowship position on any scientific topic covered by the...
An international team of astronomers, including Diana Ismail from Strasbourg astronomical observatory, has observed a galaxy in the early universe that is gravitationally lensed into the rare form of an “Einstein Cross”, including a central fifth image. Using observations from...
The Imaging X-ray Polarimetry Explorer (IXPE), a NASA mission in collaboration with the Space Italian Agency (ASI), has resolved a fundamental question concerning the origin of X-rays in blazar jets. These supermassive black holes, whose relativistic jets are directed towards the Earth, are still...
