Astronomers using the NASA/ESA/CSA James Webb Space Telescope together with the NASA/ESA Hubble Space Telescope have looked deeply at thousands of young star clusters in four nearby galaxies, studying clusters at different stages of evolution. Their findings show that more massive star clusters emerge more quickly from the clouds theyContinuar Leyendo
The Copernicus Sentinel-1D satellite, launched last November, is now fully operational after successfully completing its critical in-orbit commissioning phase. With all four Sentinel-1 satellites having now been deployed, this achievement marks a major milestone for this flagship radar mission – a journey that began more than a decade ago andContinuar Leyendo
Paris, April 29, 2026.- Space Rider is set to be the first reusable European spacecraft. The uncrewed robotic laboratory will stay in low orbit for about two months. Space Rider’s cargo bay will allow for all manner of experiments and operations to be run. At the end of its missions,Continuar Leyendo
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
