Astronomers have observed what they are calling a new type of supernova, which has provided an unparalleled glimpse into what happens deep within a star just before it explodes. A study detailing the ...

The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. They’re bright enough to see across large ...

Around July 4, 1054, Chinese astronomers recorded a “guest star” that shone so brightly, it was visible in broad daylight for 23 days. The remnants of that long-ago supernova now form the Crab Nebula, ...

BERKELEY, CA — A group of scientists affiliated with the SuperNova Legacy Survey (SNLS) have found startling evidence that there is more than one kind of Type Ia supernova, a class of exploding stars ...

Peering deeply into the cosmos, NASA's James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current ...

An international team of astronomers has conducted optical and near-infrared observations of a supernova designated SN ...

Supernovae produced much more of the stardust that builds our world than once thought, according to new research. The nuclear reactions inside stars create all the chemical elements from carbon to ...

Berkeley Lab astrophysicist Peter Nugent, working with Adam Riess of the Space Telescope Science Institute, used an IBM SP supercomputer at NERSC to analyze data from an exploding star that had been ...

Interesting! I didn't realise fusion of Helium could happen at the surface of a star, due to lack of necessary temperature and pressure. I'd been reading about reactions that produce most heavier ...

A distant stellar explosion has offered astronomers a rare natural experiment, one that turns gravity into a powerful optical ...
