París, Nov 20, 2025.- Astronomers recently discovered the 40 000th near-Earth asteroid! These space rocks range from a few metres to a few kilometres in size and are on orbits that bring them relatively close to Earth. Each new discovery is both a reminder of our planet’s vulnerability and aContinuar Leyendo
Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of small, very distant galaxies that have mystified astronomers, CANUCS-LRD-z8.6 represents a vital piece of this puzzle that challengesContinuar Leyendo
Last week, four lasers were projected into the skies above the European Southern Observatory’s (ESO’s) Paranal site in Chile. The lasers are each used to create an artificial star, which astronomers use to measure and then correct the blur caused by Earth’s atmosphere. The striking launch of these lasers, oneContinuar Leyendo
A spooky bat has been spotted flying over the European Southern Observatory’s (ESO’s) Paranal site in Chile, right in time for Halloween. Thanks to its wide field of view, the VLT Survey Telescope (VST) was able to capture this large cloud of cosmic gas and dust, whose mesmerising appearance resemblesContinuar Leyendo
A powerful new telescope has captured its first glimpse of the cosmos, and could transform our understanding of how stars, galaxies and black holes evolve. Cambridge, Oct 24, 2025.- The 4MOST (4-metre Multi-Object Spectroscopic Telescope), mounted on the European Southern Observatory’s VISTA telescope in Chile, achieved its ‘first light’ onContinuar Leyendo
On Mars, dust devils and winds reach speeds of up to 160 km/h and are therefore faster than previously assumed: This shows a study by an international research team led by the University of Bern. The researchers analyzed images taken by the Bernese Mars camera CaSSIS and the stereo cameraContinuar Leyendo
The NASA/ESA/CSA James Webb Space Telescope has provided the first direct measurements of the chemical and physical properties of a potential moon-forming disc encircling a large exoplanet. The carbon-rich disc surrounding the world called CT Cha B, which is located 625 light years away from Earth, is a possible constructionContinuar Leyendo
In our nearby stellar neighbourhood, a burned-out star is snacking on a fragment of a Pluto-like object. With its unique ultraviolet capability, only the NASA/ESA Hubble Space Telescope could identify that this meal is taking place. Paris, Sept 19, 2025.-The stellar remnant is a white dwarf about half the massContinuar Leyendo
Washington, Sept 11, 2025.- Una muestra recolectada por el rover Perseverance, el vehículo explorador de la NASA en Marte, en el antiguo lecho de un río seco en el cráter Jezero podría conservar evidencia de vida microbiana antigua. Tomada el año pasado de una roca llamada Cheyava Falls, la muestra,Continuar Leyendo
Astronomers have detected an explosion of gamma rays that repeated several times over the course of a day, an event unlike anything ever witnessed before. The source of the powerful radiation was discovered to be outside our galaxy, its location pinpointed by the European Southern Observatory’s Very Large Telescope (VLT).Continuar Leyendo
