The rotation of a protoplanetary disc (a disc where planets are being formed) has been observed directly for the very first time by mapping the emissions from the dust grains within it. The disc in question surrounds the young star AB Aurigae. Although it appears to generally rotate in accordance with the laws of physics, certain regions close to the star show an unexpected departure from this behaviour. A body of evidence suggests that this anomaly is caused by the presence of giant planets (…)

In a unique international experiment involving biologists from Europe, the Middle East, and the United States, hundreds of small plots of Arabidopsis, the standard laboratory plant, were sown in various types of climates, ranging from the alpine mountains of the Lautaret Garden (UGA/CNRS) to deserts. Scientists allowed them to evolve over a three-year period. These simultaneous experiments demonstrated that this adaptation can occur in just three generations, identified the genetic variants (…)

Using the NIKA2 camera on IRAM’s 30-metre telescope, an international team of astronomers, including scientists from the Marseille Astrophysics Laboratory (amU/CNES/CNRS) and the Grenoble Institute of Planetology and Astrophysics (IPAG-OSUG, UGA/CNRS), have achieved a new sensitivity record and discovered a vast cosmic structure comprising massive, dust-rich galaxies dating back to a time when the universe was only one billion years old. The results of this work were published on January 26, (…)

An international team led by scientists from Université Grenoble Alpes and CNRS, within the Grenoble Institute of Environmental Geosciences (IGE / OSUG – CNRS/INRAE/IRD/UGA – Grenoble INP-UGA), has demonstrated in a study published on 29 October 2025 in Nature that 60% of the floating ice shelves surrounding the Antarctic ice sheet could be destined to disappear in the long term. These ice shelves currently act as a brake on the contribution of the Antarctic ice sheet to global sea-level (…)

► One of the main objectives of contemporary astronomy is the search for exoplanets, which provide a better understanding of how planetary systems form. ► For the first time since its launch in 2021, the James Webb Space Telescope has enabled the discovery of a new exoplanet; it is located in the debris disk of a young star. ► It is the lightest planet observed by direct imagery, and represents an important stage in the imaging of less and less massive planets that are more comparable to the (…)

Since 2000, the world’s glaciers have lost 5% of their initial volume, and 273 billion tonnes of ice are disappearing every year - the equivalent of 3 Olympic swimming pools per second. These are the results of an in-depth study of the global evolution of glaciers (excluding the Antarctic and Greenland ice sheets) between 2000 and 2023, based for the first time on a combination of field measurements and satellite observations. This unprecedented study was carried out by the Glambie (…)

A new study, supported by the Make Our Planet Great Again program as part of the HOTCLIM project, and conducted by an international scientific team led by the Institute of Environmental Geosciences in Grenoble (IGE – CNRS/INRAE/IRD/UGA - Grenoble INP-UGA) in collaboration with the Laboratory of Climate and Environmental Sciences, LSCE (CEA/CNRS/UVSQ), the University of New South Wales, and the University of Bern, has revealed new rapid variations within global fluctuations of atmospheric (…)

A collaborative effort between the newly established research institute, Paleotechnic, and several national laboratories (INRAE, University of Orléans) has led to the discovery of a dam, a water treatment facility, and a hydraulic elevator, which would have enabled the construction of the Step Pyramid of Saqqara.

Wading through the wealth of data from ESA’s Gaia mission, scientists have uncovered a ‘sleeping giant’. A large black hole, with a mass of nearly 33 times the mass of the Sun, was hiding in the constellation Aquila, less than 2000 light-years from Earth. This is the first time a black hole of stellar origin this big has been spotted within the Milky Way. So far, black holes of this type have only been observed in very distant galaxies. The discovery challenges our understanding of how (…)

Global warming results in the dissapearance of meteorites, and as such reduces our access to extraterrestrial material... A team of researchers, involved researcher from Institut des géosciences de l’environnement (IGE-OSUG, CNRS/UGA/IRD/INRAE/Grenoble INP - UGA) and co-led by ULB and its Laboratoire de glaciologie (GLACIOL), publishes a study in Nature Climate Change on this unexpected impact of climate change, which is hampering our knowledge of the solar system.
