   Feb 19, 2014 · 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. “With NuSTAR we have a new forensic tool to investigate the explosion,” said the paper’s lead author, Brian Grefenstette of Caltech.

   Oct 31, 2019 · What happens when a star explodes? Surprisingly, the same thing that happens when gas explodes here on Earth. For explosions to occur, there needs to be a build-up of pressure.

   Sep 16, 2020 · A visualization flying into the nebula Gum 29 and the star cluster Westerlund 2 at its core. All stars are born in clouds of dust and gas like the Pillars of Creation in the Eagle Nebula pictured below. In these stellar nurseries, clumps of gas form, pulling in more and more mass as time passes. As they grow, these clumps start to spin and heat up.

   What happens when a star explodes?

   • However, in the case of stars, their life often ends with an explosion in their final stage; this is called a supernova. Supernovas are believed to be essential and are thought to be one of the sources of the elements heavier than iron in the universe. This material is then expelled across space, where some of it rains down on Earth.

   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 when a star reaches the end of its life?

   • When a star reaches the end of its life, it explodes, causing a supernova. How does this happen, and what’s the impact? Stars, just like living organisms, go through a life cycle, and then they die. However, in the case of stars, their life often ends with an explosion in their final stage; this is called a supernova.

   When did a star eject gas from Earth?

   • The gas was probably ejected by the central star about 1,200 years ago. In the right-hand image, the Cat's Eye Nebula, 3,300 light years from Earth in the constellation Draco, exhibits 11 concentric rings of dust, which astronomers estimate were released at 1,500-year intervals.

   What happens if a star bloats at the end of its life?

   • At the end of their lives, sunlike stars metamorphose into glowing shells of gas –  perhaps shaped by unseen companions. Billions of years from now, as our Sun approaches the end of its life and helium nuclei begin to fuse in its core, it will bloat dramatically and turn into what's known as a red giant star.

   What happens if a star dies in a supernova?

   • Stars that end their life as a type II supernova are supermassive, usually with eight to fifteen times the mass of our Sun. When these stars eventually run out of first hydrogen and then helium fuel, they will still have enough mass and pressure to fuse carbon. Gradually heavier elements build up at the core.
