What is supernova short answer? A supernova is a large explosion that takes place at the end of a star’s life cycle. On the left is Supernova 1987A after the star has exploded. On the right is the star before it exploded.
What is a supernova and what causes it? When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds. This collapse produces the explosion we call a supernova. Supernovae are so powerful they create new atomic nuclei.
What are supernovas made of? Iron atoms become crushed so closely together that the repulsive forces of their nuclei create a recoil of the squeezed core—a bounce that causes the star to explode as a supernova and give birth to an enormous, superheated, shock wave.
Can a supernova explosion destroy Earth? A supernova is a spectacular explosion of a massive star. If our sun exploded as a supernova, the resulting shock wave probably wouldn’t incinerate the entire Earth, but the side of Earth facing the sun would boil away.
