A supernova is a massive stellar explosion that occurs when a star reaches the end of its life. In seconds, it releases more energy than our Sun will emit in its entire lifetime. The outer layers of the star are blasted into space, creating stunning clouds of gas and dust, while the core collapses into a neutron star or a black hole. Supernovae also seed the universe with heavy elements essential for planets and life. #space #viralpost2025シ #viralvideoシ #usa_tiktok #supernova #astronomy | Modern
