   A supernova (pl.: supernovae or supernovas) is a powerful and luminous explosion of a star. A supernova 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 ...

   Oct 11, 2024 · One type of supernova is caused by the “last hurrah” of a dying massive star. This happens when a star at least five times the mass of our sun goes out with a fantastic bang! Massive stars burn huge amounts of nuclear fuel at their cores, or centers. This produces tons of energy, so the center gets very hot. Heat generates pressure, and the ...

   Feb 19, 2014 · In this case, the element is titanium-44, which has an unstable nucleus produced at the heart of the exploding star. These illustrations show the progression of a supernova blast. A massive star (left), which has created elements as heavy as iron in its interior, blows up in a tremendous explosion (middle), scattering its outer layers in a structure called a supernova remnant (right).

   What happens if a star explodes?

   • The result is a type Ia supernova explosion. Just as people do, stars have a finite life. Born in dusty gas clouds of a galaxy’s spiral arms, stars fuse hydrogen into heavier elements during their energy-producing lifetimes. For stars, mass translates into destiny. The smallest can glow like embers for trillions of years.

   What happens if a supernova explodes?

   • When researchers simulate supernova blasts with computers, as a massive star dies and collapses, the main shock wave often stalls out and the star fails to shatter. The latest findings strongly suggest the exploding star literally sloshed around, re-energizing the stalled shock wave and allowing the star to finally blast off its outer layers.

   What happens if a star goes out with a great bang?

   • This happens when a star at least five times the mass of our sun goes out with a fantastic bang! Massive stars burn huge amounts of nuclear fuel at their cores, or centers. This produces tons of energy, so the center gets very hot. Heat generates pressure, and the pressure created by a star’s nuclear burning also keeps that star from collapsing.

   What happens if a star collapses?

   • For core masses of 40–60 M☉, the collapse halts and the star remains intact, but collapse will occur again when a larger core has formed. For cores of around 60–130 M☉, the fusion of oxygen and heavier elements is so energetic that the entire star is disrupted, causing a supernova.

   What happens during a supernova?

   • A supernova 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 to form a diffuse nebula.

   What causes a supernova explosion?

   • Once the burning is fast enough, this creates pressure so quickly that it doesn’t have time to dissipate, eventually causing a detonation. The same process seems to be behind supernova explosions, says Poludnenko. “We also see in the simulations that this happens in a star, it’s the same mechanism.”
