For the primary time, a staff of astronomers has captured a transparent picture of a white dwarf star that exploded not simply as soon as, however twice, as a Kind Ia supernova — a “double-detonation” that scientists hadn’t thought potential till now. The extraordinary remark may revise our long-held notions of how stars die, suggesting that some stars can explode as supernovas with out ever crossing the Chandrasekhar restrict, the minimal mass usually thought essential for such an explosion. The astronomers employed the Very Giant Telescope’s MUSE instrument to zoom in on the four-century-old supernova remnant SNR 0509-67.5, which sits 60,000 light-years away within the constellation Dorado, revealing proof of two separate blasting catastrophes in its development.
