What energy does a supernova produce?

What energy does a supernova produce?

1044 joules
A supernova is an explosion of a massive supergiant star. It may shine with the brightness of 10 billion suns! The total energy output may be 1044 joules, as much as the total output of the sun during its 10 billion year lifetime.

What happens when a star goes supernova?

Supernovae are so powerful they create new atomic nuclei. As a massive star collapses, it produces a shockwave that can induce fusion reactions in the star’s outer shell. These fusion reactions create new atomic nuclei in a process called nucleosynthesis.

Can a supernova 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.

What elements do supernovae produce?

The elements formed in these stages range from oxygen through to iron. During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced. In the supernova explosion, all of these elements are expelled out into space.

Can a supernova create a black hole?

Failed supernovae are thought to create stellar black holes by the collapsing of a red supergiant star in the early stages of a supernova. The observed instances of these disappearances seem to involve supergiant stars with masses above 17 solar masses.

Can a supernova destroy an entire galaxy?

Supernovas are created during the last moments of a star’s life. These gigantic explosions can wipe out galaxies and the planets inside them. These powerful eruptions are called supernovae. They can emit the same energy in a single instant that our sun will generate in over 1 million years.

Can a star become a black hole without supernova?

But that chain can only be carried up to iron. After that, fusing heavier elements costs you energy rather than releases it. So, the core collapses, creating a shock wave that rips the star apart. Above that mass, stars are so massive that they likely collapse into a black hole directly, without becoming a supernova.
