The star is the first unambiguous example of chemical enrichment by the first stars in the Universe within a primordial environment. Tucson, March 16, 2026.- Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron — less than 1/40,000th of the Sun. This signature makesContinuar Leyendo
A new European Space Agency facility that will use artificial intelligence to advance satellite-enabled connectivity is being developed in the UK. Barcelona, 06 March, 2026.- Backed by the UK Space Agency, ESA’s AI Hub will offer a unique environment where European industry can test, validate and scale AI-driven innovations forContinuar Leyendo
Webb provides the first vertical view of the planet’s ionosphere, revealing auroras shaped by its tilted magnetic field. For the first time, an international team of astronomers have mapped the vertical structure of Uranus’s upper atmosphere, uncovering how temperature and charged particles vary with height across the planet. Using Webb’sContinuar Leyendo
Bern, Jan 27, 2026.- A new study led by the University of Bern has discovered a large number of bright streaks, also known as «lineae», on Mercury, which are presumably caused by the outgassing of volatile material from the planet’s interior. This indicates that Mercury is not a dead planet,Continuar Leyendo
First spotted in the early 1800s, the Helix Nebula has become one of the most iconic planetary nebulas in the sky as it’s recognised for its striking, ring-like shape. One of the closest planetary nebulas to Earth, it has become a favourite among astronomers using ground- and space-based telescopes toContinuar Leyendo
Astronomers have spotted one of the oldest ‘dead’ galaxies yet identified, and found that a growing supermassive black hole can slowly starve a galaxy rather than tear it apart. Cambrigde, Jan 16, 2026.- The researchers, led by the University of Cambridge, used data from the James Webb Space Telescope andContinuar Leyendo
A team using the NASA/ESA Hubble Space Telescope has uncovered a new type of astronomical object —a starless, gas-rich, dark-matter cloud that is considered a “relic” or remnant of early galaxy formation. Nicknamed “Cloud-9,” this is the first confirmed detection of such an object in the Universe. The finding furthersContinuar Leyendo
At its Ministerial Council meeting, the European Space Agency (ESA) has approved the RAMSES mission. The joint mission by ESA and the Japan Aerospace Exploration Agency JAXA will investigate the flyby of the asteroid «Apophis» by Earth in April 2029. The University of Bern is involved in the mission withContinuar Leyendo
Este jueves tuvo lugar la ceremonia de colocación de la primera piedra de la instalación del conjunto sur del CTAO en la ubicación que el Observatorio Europeo Austral (ESO) le ha destinado en Paranal (Chile), marcando el inicio de la construcción de los cimientos del telescopio. El CTAO (siglas deContinuar Leyendo
The NASA/ESA/CSA James Webb Space Telescope has confirmed the source of a super-bright flash of light known as a gamma-ray burst, generated by an exploding massive star when the Universe was only 730 million years old. For the first time for such a remote event, the telescope provided a detectionContinuar Leyendo
