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.
Researchers have detected erythrulose, a four-carbon sugar, in the interstellar medium near the Milky Way’s center. The finding supports theories that sugars essential to life could form in space and arrive on Earth via comets and asteroids. The study, published in Nature Astronomy, suggests that millions of tonnes of erythrulose may have rained down on Earth during the Late Heavy Bombardment.
Scientists have identified a 222‑metre‑wide, up to 43‑metre‑deep crater on the Moon formed in spring 2024 and first spotted in LRO images in 2025. The impact churned material across more than 100 km, produced a roughly 7‑km cold spot and has provided rare data scientists say will inform risk assessments for planned lunar bases.
