This is how a star dies in a colossal explosion called a supernova. | NOVA l PBS

✨ Supernova: The spectacular and powerful explosion marking the final stage of a massive star's life. 💥 Hypernova: An even more extreme version! This is an incredibly energetic supernova resulting from the collapse of a star more than 30 times the mass of our sun. 💫 Kilonova: A colossal event that happens when two super-dense objects, like two neutron stars or a neutron star and a black hole, collide and merge. The scale of the universe is just awe-inspiring! #SpaceFacts #Astronomy #Space #Cos

What does a supernova look like? This visualization simulates the first 150 milliseconds of a supernova. As the star collapses in on itself, hot gas emits from its core in uneven shock waves. Researchers use computer simulations like this to more accurately understand the events of a dying star. | NASA Ames Research Center
