WASHINGTON (Reuters) -The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times the mass of our sun that exhausts its nuclear fuel ...

Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...

The James Webb Space Telescope (JWST) and its JADES program have identified AT2023 ADS-V, a core-collapse supernova occurring 1.7 billion years after the Big Bang, representing the most distant ...

Imagine watching a massive star that's been burning steadily for millions of years suddenly dim, fluctuate, and then vanish completely from the night sky. This isn't science fiction. It's happening ...

Supernovae represent the dramatic endpoints of stellar evolution, and recent studies have expanded our understanding of the complex interplay between explosion mechanisms and the nature of progenitor ...

Every so often, a mysterious so-called "guest star" appears in the sky, often far outstripping its cousins in brightness. Astronomers and stargazers have known about such events since at least 185 AD ...

A special group of East Tennessee scientists who build computer models of stars that exploded eons ago are awaiting a special signal. It will tell them more about the “central engine” that drove one ...

You might think of a star as a mass of incandescent gas, a gigantic nuclear furnace where hydrogen is turned into helium at a temperature of millions of degrees. But researchers recently reported that ...

A supernova observed last year was so bright–about 100 times as luminous as a typical supernova–that it challenged the theoretical understanding of what causes supernovae. But Stan Woosley, professor ...
