According to a press release from the Lyon Observatory dated September 4, 2025, based on a scientific publication to which Elliot Lynch, researcher at CRAL (ENS de Lyon/CNRS/UCBL), contributed as part of an international team: “ALMA Reveals an Eccentricity Gradient in the Fomalhaut Debris Disk”, published in The Astrophysical Journal on September 4, 2025.

National press release. The 4MOST instrument, installed in Chile on the European Southern Observatory's (ESO) VISTA telescope and developed largely by teams from the CNRS, Université Claude Bernard Lyon 1, and ENS de Lyon, has just achieved first light. This first ray of light from space, analyzed by the instrument's spectrographs, marks the beginning of a great adventure in studying and mapping the sky: thanks to its cutting-edge technology, 4MOST can study the light from 2,400 celestial objects simultaneously, every 15 minutes.

On Wednesday 19 March 2025, the CRAL, Lyon's Astrophysics Research Centre, received a visit from the Chilean Ambassador, Mr Raúl Fernández Daza, accompanied by the Honorary Consul of Chile in Lyon, Mr Ignacio Velasco Arellano. The purpose of the visit was to present the CRAL's research activities, and in particular its involvement in major instrumental projects on Chilean telescopes.

Thomas Buchert, professor at the Université Claude Bernard Lyon 1 and member of CRAL's AstroEns team, has been awarded the international Tullio Levi-Civita prize for his innovations in Relativistic Cosmology.

Isabelle Baraffe, a member of the Centre de Recherche Astrophysique de Lyon (CRAL), is a Professor of Astrophysics on secondment at the University of Exeter, United Kingdom. In October 2024, she was awarded a prize for her pioneering research in theoretical astrophysics, which has revolutionised our understanding of the structure and evolution of stars and planets.

MUSE spectrograph reveals that nearly the entire sky in the early Universe is glowing with Lyman-alpha emission

Photo Release from the European Southern Observatory (ESO)

Through a quirk of nature called “gravitational lensing,” a natural lens in space amplified a very distant star’s light. Astronomers using Hubble took advantage of this phenomenon to pinpoint the faraway star and set a new distance record for the farthest individual star ever seen. They also used the distant star to test one theory of dark matter, and to probe the make-up of a galaxy cluster. The team dubbed the star “Icarus,” after the Greek mythological character who flew too near the Sun on wings of feathers and wax that melted. Its official name is MACS J1149+2223 Lensed Star 1.
