ESA's Mars Express orbiter has observed an impact crater in Mars's northern lowlands whose shape resembles a butterfly, created when an incoming space rock struck the surface at a shallow angle. The main crater, which appears somewhat like a walnut from orbit, measures about 20 km east to west and 15 km north to south and sits within the Idaeus Fossae region. The impact threw material preferenti

SwRI scientists report that a reanalysis of Voyager 2 measurements suggests a powerful solar storm may explain why Uranus hosts an electron radiation belt far more intense than expected. They propose that a large-scale solar wind structure, known as a co-rotating interaction region, was passing through the Uranian system during the 1986 flyby, driving extreme space weather conditions that booste

An international collaboration led by the University of Oxford has identified one of the largest rotating structures observed so far, a thin string of hydrogen-rich galaxies embedded in a spinning cosmic filament around 140 million light-years away. The work, published in Monthly Notices of the Royal Astronomical Society, offers new constraints on how large-scale structures influence the formati

Electric discharges have been detected inside dust devils and dust storms on Mars for the first time, using sound recordings from the SuperCam microphone on NASAs Perseverance rover. Scientists from CNRS, Universite de Toulouse and Observatoire de Paris PSL analysed these signals and identified them as the acoustic and electromagnetic signatures of electrical activity within Martian dust events.

An institute in Beijing plans to launch its first high-computing-power experimental satellites by late 2025 or early 2026 as part of a wider effort to move intensive data processing into orbit while easing pressure on power and land resources on the ground. Zhang Shancong, director of the Beijing Astro-future Institute of Space Technology and chief scientist at Beijing Orbit Twilight Techn
