May 14, 2023 · Supernovas are the largest explosions that take place in space. They are both destructive and an act of creation as they are the primary source of heavy elements in the universe. In a galaxy the ...
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 14, 2019 · Such stars explode when they use up their nuclear fuel and collapse. Core collapse. Stars weighing more than about eight times the Sun’s mass burn through their hydrogen fuel quickly, but as a ...
Novae occur in multiple star systems in which a white dwarf, neutron star, or even black hole draws gases from the outer atmosphere of a companion star into an envelope of matter around itself. As more matter is piled on, the gas becomes increasingly hot and dense, until the sudden onset of hydrogen fusion in the envelope triggers an enormous thermonuclear explosion.
Jul 1, 2019 · 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 ...

Apr 26, 2021 · Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA’s Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode. This work is based on Chandra observations of the remains of a supernova called Cassiopeia A, located in our galaxy about 11,000 ...
