The Franco-Chinese space mission SVOM took off on 22 June 2024. The Strasbourg Astronomical Observatory is in charge of processing the data from one of the instruments on board, the MXT X-ray camera. The main objective of the SVOM mission is to rapidly detect and analyse gamma-ray bursts, which...
Less than a year after its launch, ESA's Euclid space mission has just published five new never-before-seen views of the Universe. These images, also available with the services of the Strasbourg astronomical Data Centre, demonstrate Euclid's ability to unlock the secrets of the cosmos, in...
An international scientific team led by Grégory Desvignes, and involving Jérôme Pétri from the Strasbourg Astronomical Observatory, used the Effelsberg and Jodrell Bank radio telescopes to observe a magnetar in precession - a highly magnetised and ultra-dense neutron star - shortly after an...
Discovery of the faintest Milky Way satellite. View of the galaxy UMa3/U1 in several astronomical surveys : PanSTARRS DR1 (top left), DESI Legacy survey (top right), DECaLS DR5 (bottom left), et SDSS9 (bottom right). The red ellipse corresponds to the claimed size in the original...
The 2024 HEAD Bruno Rossi Prize, the highest distinction in high energy astrophysics, is awarded to: Martin Weisskopf, Paolo Soffitta and the IXPE team "for their development of the Imaging X-ray Polarimetry Explorer whose novel measurements advance our understanding of particle acceleration and...
Is deep learning inevitably synonymous with "black boxes"? These methods are often criticized for their lack of transparency, resulting in unintelligible models. This issue is particularly relevant in physics, where the goal is to model the laws governing our universe as comprehensible equations,...
An international team of astronomers has captured the eroded remains of 106 dwarf galaxies for the first time. They represent the missing link in their evolution into ultra-compact dwarf galaxies, objects that resemble star clusters, particularly globular clusters, in terms of density but with...
ESA’s Euclid space mission, launched in July 2023, reveals its first full-colour images of the cosmos. Never before has a telescope been able to create such razor-sharp astronomical images across such a large patch of the sky, and looking so far into the distant Universe. These five images...
At the heart of our own Galaxy, the Milky Way, lies a supermassive black hole. Located in the constellation Sagittarius, hence its name Sgr A, this black hole is currently inactive. However, strange X-ray signatures have been observed around Sgr A, suggesting that this supermassive black hole may...
The Strasbourg Astronomical Observatory is delighted to be hosting the 2023 edition of the annual days of the Société Française d'Astronomie et d'Astrophysique (SF2A), from 20 to 23 June on the Esplanade campus. More than 500 people have registered for this highlight of French...
