Explanation:

It's a balance of gravity pushing in on the star and heat and pressure pushing outward from the star's core. When a massive star runs out of fuel, it cools off. This causes the pressure to drop. ... The collapse happens so quickly that it creates enormous shock waves that cause the outer part of the star to explode!

Answer:

A 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 the progenitor, either collapses to a neutron star or 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.
