"Supernova: A stellar death that sparks new beginnings! When a star reaches the end of its life, it undergoes a dramatic collapse, resulting in one of the most luminous events in the universe. These explosions scatter elements across space, fueling the cycle of star formation and creating the very matter we are made of. Discover the cosmic fireworks that make the universe come alive. #BrianGreene #Supernova #CosmicEvent #StarExplosion #AstronomyLovers #Physics #SpaceExploration #Universe #Stella

Supernova supernova is a powerful and luminous stellar explosion. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion. The original object, called theprogenitor, either collapses to a neutron staror black hole, or is completely destroyed. The peak optical luminosity of a supernova can be comparable to that of an entire galaxy before fading over several weeks or months. | Free AstroScience
