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
Bern, Sept 08, 2025.- The University of Bern is participating in the international NASA Interstellar Mapping and Acceleration Probe mission (IMAP), which is due to be launched no earlier than 23 September 2025. IMAP is dedicated to exploring the outer limits of the heliosphere, the protective bubble of solar windContinuar Leyendo
The NASA/ESA/CSA James Webb Space Telescope has revealed new details in the core of the Butterfly Nebula, NGC 6302. From the dense, dusty torus that surrounds the star hidden at the centre of the nebula to its outflowing jets, the Webb observations reveal many new discoveries that paint a never-before-seenContinuar Leyendo
Coventry, Aug 13, 2025.- An international team of astronomers using the NASA/ESA Hubble Space Telescope have discovered a stellar rarity: an ultra-massive white dwarf that formed when a white dwarf merged with another star, rather than through the evolution of a single star. This discovery, which was made possible byContinuar Leyendo
More than one star contributes to the irregular shape of NGC 6072 París, July 30, 2025.- Webb’s newest look at planetary nebula NGC 6072 in the near- and mid-infrared shows what may appear as a very messy scene resembling splattered paint. However, the unusual, asymmetrical scene hints at more complicatedContinuar Leyendo
To mark its third year of highly productive science, astronomers used the NASA/ESA/CSA James Webb Space Telescope to scratch beyond the surface of the Cat’s Paw Nebula (NGC 6334), a massive, local star-forming region. Paris, July 10, 2025.- Webb’s NIRCam instrument was used to look at this particular area ofContinuar Leyendo
