Astronomers have obtained the first compelling visual evidence confirming the double-detonation theory of Type Ia supernovae, where a white dwarf star explodes twice in rapid succession. Using the European Southern Observatory's Very Large Telescope (VLT), researchers captured images of the supernova remnant SNR 0509-67.5, located approximately 400 years old, revealing two concentric rings indicative of two separate explosions. The initial blast is attributed to helium buildup on the white dwarf's surface, followed by a second detonation that completely destroyed the star. This discovery provides tangible proof for a long-debated hypothesis about the mechanisms behind certain supernovae and offers new insights into cosmic phenomena that contribute to elements such as iron in the universe. The images and data mark a milestone in understanding stellar death and the complex processes involved in supernova explosions.
