Intergovernmental body advancing ground-based astronomy in the Southern Hemisphere
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.
A SpaceX Falcon 9 upper stage has struck the Moon near Einstein Crater at about 5,400 mph, carving a new crater and launching a dust plume. South Korea’s Danuri orbiter has photographed the site and released images. NASA’s Lunar Reconnaissance Orbiter is scheduled to image the impact next week while scientists begin analysing ejecta and crater formation.
