🪐 In 2014, astronomers observed supernova SN 2014J exploding in the nearby galaxy Messier 82, just 11.4 million light-years from Earth. This event was one of the closest Type Ia supernovae seen in decades—Type Ia supernovae occur when a white dwarf star (a dense, Earth-sized star remnant) gains too much mass from a companion and detonates, serving as important cosmic "standard candles" to help measure the scale of the universe. ✨ #supernovae⚡#messier82⚡#whiteDwarf⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
