A new study reveals that a pair of white dwarf stars, located just 150 light-years from Earth, are set to explode in a type 1a supernova in approximately 23 billion years, shining 10 times brighter than the moon. This binary system, WDJ181058.67+311940.94, has a combined mass exceeding 1.56 times that of the sun, making it a record-setting system for its type. The supernova will consist of four explosions triggered by the stars’ close orbit, providing researchers with valuable insights into the mechanisms behind such stellar events and the potential for discovering more similar systems nearby.
