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...
A recent study, led by Dr. Mélina Poulain from the University of Oulu, reports the first direct observation of merging star clusters in the nuclear region of dwarf galaxies. This detection confirms the feasibility of this formation route for nuclei in dwarf...

Filaments are slender, thread-like structures of dark matter, gas and galaxies, forming a complex network known as the cosmic web. Theoretical models predict that they attract and channel cold gas to fuel star formation in galaxies. An international team including two researchers from Strasbourg...
The European Space Agency’s Milky Way-mapper Gaia has completed the sky-scanning phase of its mission, racking up more than three trillion observations of about two billion stars and other objects over the last decade to revolutionise the view of our home galaxy and cosmic...
On 10 December 1999, the Ariane 504 rocket, which at the time had a lot to make up for after dropping the Clusters mission in the mangroves of French Guiana, pulled out all the stops to place a 4-tonne, 10-metre-high monster into an orbit rising to 114,000 km. Artist's view of the XMM satellite...
