On 14 September, 2015, the international LIGO/Virgo collaboration detected the very first gravitational wave signal, a tiny distortion of spacetime predicted by Einstein, in this case produced by the merger of two black holes. The CNRS astrophysicist Marie-...
Why is the outermost part of the Sun's atmosphere, the corona, so much hotter than its surface? Ten years after formulating a hypothesis based on a numerical model, CNRS researchers have now used direct observations of the star's surface to confirm...
With large-scale observation campaigns, innovative data analysis methods and theoretical advances on all fronts, astrophysics and cosmology are entering a high-precision era with the potential to unravel many of the unsolved mysteries of the Universe....
During his “miraculous year” 120 years ago, Albert Einstein explained the photoelectric effect, laying the foundations of quantum mechanics. The historian of science Christian Bracco provides an insight.
Today the American (NASA), European (ESA), and Canadian (CSA) space agencies released the first colour images and spectroscopic data from the James Webb Space Telescope (JWST). Coordinator of one of...
The aim of several scientists is to trace the changes of a comet during its journey through the Solar System by reproducing the thermal and light characteristics of the cosmos in the laboratory....
Scientists were aware there was a huge object hidden at the centre of the Milky Way, and they also knew it had no hair. The EHT collaboration has now obtained the very first image of Sagittarius A*,...
