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...
The team working on the ground segment of the MXT camera for the French-Chinese SVOM missionmission has a vacancy for a Python DevOps developer.This contract, initially for 12 months, may be extended to 36 months.The skills required are: Python, Angular, Git, Docker.Knowledge of statistics and...
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...
An American team has just published an article in Nature highlighting the presence of a third star orbiting the high-mass X-ray binary (HMXB) V404 Cygni. The discovery of this third distant companion suggests that the stellar black hole at the heart of the X-ray binary may have formed without a...
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...
