🪐 In the spiral galaxy NGC 2525, located around 70 million light-years from Earth, astronomers watched supernova SN 2018gv gradually fade over 2018 and 2019 in real time. This stellar explosion outshone its entire galaxy for weeks—when a white dwarf star in a close binary system grew too heavy and detonated, releasing enough energy to briefly rival the brightness of billions of suns before slowly fading back into darkness. ✨ #supernova⚡#NGC2525⚡#astronomy⚡#nasa⚡#galaxy⚡#stars⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
