Astronomers have detected helium escaping from LHS 1140b, a rocky 'super-Earth' 48 light-years away that orbits in its star's habitable zone. The finding has confirmed an atmosphere around a habitable-zone rocky exoplanet for the first time and has been published in Science; teams used ground-based infrared spectroscopy and modelling.
Durham researchers using supercomputer simulations show that a head‑on collision with Gaia Sausage likely caused a dramatic reorientation of the Milky Way’s disc, a process scientists describe as a “disc flip.” The event would have reshaped the galaxy’s spokes, bulge and halo, potentially altering the Solar System’s ancient path.
A total solar eclipse has crossed Greenland, Iceland and northern Spain while the UK and Ireland have seen a deep partial eclipse — the most extensive across Britain since 1999. Scientists and agencies such as NASA have flown instruments and balloons into the path of totality to study the Sun's corona and to gather data for improving space‑weather forecasts.
