2022年6月27日 The Gum Nebula over Snowy Mountains Image Credit & Copyright: Wang Jin Explanation: The Gum Nebula is so large and close it is actually hard to see. This interstellar expanse of glowing hydrogen gas frequently evades notice because it spans 35 degrees — over 70 full Moons — while much of it is quite dim. This featured spectacular ...
CAPSTONE, the pathfinder for NASA’s lunar outpost, will test an orbit around the Moon that has never been flown before. In this image from April 2022, the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, was undergoing final construction – and with solar panel installation and vibration testing now complete...
