JWST studies a supernova near the dawn of time
A long time ago, in a galaxy far, far away, a massive star collapsed, triggering a supernova explosion so bright it could be seen across the universe. When the light reached Earth, telescopes around ...
The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA's Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they ...
Add Yahoo as a preferred source to see more of our stories on Google. ALMA found two hot molecular cores inside a supernova remnant, with organic chemistry that appears surprisingly intact. (CREDIT: ...
Artist’s impression of a hot core—a warm cocoon of molecular gas surrounding a newborn star—discovered in a supernova remnant. Blue represents high-energy regions produced by the supernova explosion, ...
A supernova remnant is supposed to be a rough neighborhood for a newborn star. Shock waves rip through space at thousands of kilometers per second. Cosmic rays and X-rays flood nearby gas. Rare ...
