Supernova

Few photography subjects offer the breadth of beauty as astronomy, and the Royal Observatory Greenwich’s annual Astronomy Photographer of the Year awards celebrate that. The winners for 2024 have now been crowned, including breathtaking cosmic shots.

NASA’s Transiting Exoplanet Survey Satellite was built to search for new planets, but astronomers at Ohio State found it could also observe supernovas created by exploding white dwarf stars. This means we might soon have a better idea about why they explode, and what they leave behind.
