A binary star system called V Sagittae, located about 10,000 light-years away, is on the verge of a supernova explosion due to a white dwarf star rapidly consuming its larger companion, which will be visible from Earth during the day. The system's extreme brightness and impending explosion have been studied using the Very Large Telescope, revealing a giant gas ring and signs of an imminent nova or supernova event. This rare cosmic event could reshape our understanding of stellar life cycles.
