Astronomers Capture First-Ever Image of a Dead Star That Exploded Twice in Rare Supernova Event

Astronomers have captured the first-ever image of a white dwarf star undergoing a rare double-detonation supernova. Using the Very Large Telescope, the team revealed that such explosions can occur without a star reaching the Chandrasekhar limit. The findings, published in Nature Astronomy, could reshape existing theories about stellar death and improve our understanding of cosmic distance measurement.
