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.

Is a supernova the death of a star?
A supernova is what happens when a star has reached the end of its life and explodes in a brilliant burst of light. Supernovae can briefly outshine entire galaxies (opens in new tab) and radiate more energy than our sun (opens in new tab) will in its entire lifetime.
What is the closest dying star to Earth?
Betelgeuse is the nearest red supergiant star to Earth and it has been predicted to explode.
Would 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.
Less Than Five - What Is A Supernova?
How is a supernova born?
A star can go supernova in one of two ways: Type I supernova: star accumulates matter from a nearby neighbor until a runaway nuclear reaction ignites. Type II supernovaType II supernovaA Type II supernova (plural: supernovae or supernovas) results from the rapid collapse and violent explosion of a massive star.https://en.wikipedia.org › wiki › Type_II_supernovaType II supernova - Wikipedia: star runs out of nuclear fuel and collapses under its own gravity.
Can a star survive a supernova?
A small per cent of massive stars end their life with this massive explosion, mostly leaving next-to-nothing behind. This is why astronomers were surprised to observe the supernova SN 2012Z with the Hubble Space Telescope: Not only had a star survived the explosion, but it actually became brighter than it was before.
Will the star explosion in 2022 destroy Earth?
Suppose for instance if Supernova due to Betelgeuse is going to happen in 2022, then we don't need to fear at all. Betelgeuse is more than 500 light-years away from us and it would not have any harmful effect on us due to such a large distance.
Astrophysics Deep Dive: What Causes A Supernova?
Is a supernova a dying star?
In a nutshell, a supernova is the violent explosion of a dying star. There are several sorts of supernova explosions, but all may generate more energy in a few seconds than our sun does in its whole lifetime. For a brief moment, certain supernovae may outshine an entire galaxy.
Can the Earth get destroyed in a supernova?
If a supernova explosion were to occur within about 25 light-years of Earth, our planet would probably lose its atmosphere, and all life would perish. However, astronomers haven't found any dangerous supernova candidates in our cosmic backyard, so there's no reason to worry.
Inside A Supernova - What Happens Before A Star Explodes
Can anything survive a supernova?
Can life survive? There is no way for life to survive on the surface of a planet witnessing a supernova. As shown above, a habitable planet orbiting Betelgeuse will lose at least 4 km of its surface, vaporized to space.
What are dying stars?
Like celestial chemical factories, stars spend their lives fusing hydrogen and helium atoms to forge heavier elements. In death, extremely massive stars explode in a supernova, blasting their chemical creations into space, and seeding the universe for a new generation of stars to grow.
