Why do collapsing stars explode?
Why do collapsing stars explode?
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!
What happens when a star collapses and explodes?
The process of collapse releases enough energy to rip the star’s outer layers to bits and blast them into space at several percent of the speed of light. These fragments carry helium, calcium, oxygen, carbon, and other elements into space, where they may someday be incorporated into new stars and planets.
What happens when a star collapsed?
In collapsed stars, matter has been pushed to the limit. In the normal course of its life, this pressure is provided by the energy produced in nuclear reactions deep in the center of the star. When those nuclear reactions stop producing energy, the pressure drops and the star falls in on itself.
What is it called when a star collapses then blows apart?
Bottom line: A supernova is the cataclysmic explosion of a star at the end of its life. Supernova explosions come in different types, but all can emit more energy in a few seconds than our sun over its entire lifetime. Some supernovae outshine an entire galaxy for a brief period.
Why Earth doesn’t fall on its own?
PERIOD! Well, the short answer is that the earth is not massive enough. Although like any other body, gravity tries to collapse earth, this inward pull is resisted by the materials that make up our planet. The atoms that compose these materials repel one another and prevent this collapse.
Why does a star collapse into a black hole?
Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.) When the surface reaches the event horizon, time stands still, and the star can collapse no more – it is a frozen collapsing object.
