AnswerA supernovae is the colossal explosion of a star.:
Explanation:
For most of the life of a star, inward gravity and outward pressure are in balance and the star is stable., but as a star burns through its fuel and begins to cool, the outward forces of pressure drop.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.
