A novel study reveals a significant decline in glaciers on a global scale

Published on February 20, 2025

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], made up (…)

Sleeping giant surprises Gaia scientists

Published on April 16, 2024
ESA

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 (…)

Climate change reduces our access to extraterrestrial material

Published on April 10, 2024
Université libre de Bruxelles

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.

Groundbreaking survey reveals secrets of planet birth around dozens of stars

Published on March 07, 2024
ESO Press release

In a series of studies, a team of astronomers, involved scientists from institut de Planétologie et d’Astrophysique de Grenoble (IPAG-OSUG, CNRS/UGA), has shed new light on the fascinating and complex process of planet formation. The stunning images, captured using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile, represent one of the largest ever surveys of planet-forming discs. The research brings together observations of more than 80 young stars that might (…)

A great success for Beyond EPICA third drilling campaign: reached 1836 meters of depth in the Antarctic ice sheet

Published on March 05, 2024

In Antarctica, the third drilling campaign of the Beyond EPICA (European Project for Ice Coring in Antarctica) - Oldest Ice project, at the remote field site Little Dome C, has been successfully completed. The goal to go back 1.5 million years in time to reconstruct past temperatures and greenhouse gas concentrations, through the analysis of an ice core extracted from the depths of the ice sheet, becomes each year more real.
Funded by the European Commission with 11 million euros and (…)

Greenland’s ice shelves have lost more than a third of their volume

Published on November 13, 2023
Alert press CNRS

The largest floating ice shelves in the polar ice sheet have lost more than a third of their volume since 1978. In a study to be published on 7 November in Nature Communications, scientists from the Institut des géosciences de l’environnement (IGE), alongside their Danish and American colleagues, have established that most of this thinning is due to the rise in surrounding ocean temperatures, which causes the glaciers’ floating extensions to melt. Until now, the glaciers in this region were (…)

Polarized X-rays reveal shape, orientation of extremely hot matter around black hole

Published on November 10, 2022

Researchers’ recent observations of a stellar-mass black hole called Cygnus X-1 reveal new details about the configuration of extremely hot matter in the region immediately surrounding the black hole. Matter is heated to millions of degrees as it is pulled toward a black hole. This hot matter glows in X-rays. Researchers are using measurements of the polarization of these X-rays to test and refine models that describe how black holes swallow matter, becoming some of the most luminous (…)
