Global cooling associated with the impact of supernova remnants may have affected plants and animals, including species related to humans.

New X-ray data from NASA’s Chandra telescope reveals Cassiopeia A’s chaotic final hours, showing how dying stars collapse and explode.

A supernova blast 2.2 billion light-years from Earth has given astronomers a deeper view into a star's centre than ever ...

This material, says a team led by astrophysicist Steve Schulze of Northwestern University in the US, constitutes the first direct evidence of the theorized concentric shells of different elements that ...

NEW YORK (AP) — Scientists for the first time have spotted the insides of a dying star as it exploded, offering a rare peek into stellar evolution. Stars can live for millions to trillions of years ...

A distant supernova exposed elements from a star’s core. The result reshapes ideas of how massive stars evolve. According to long-standing theory, stars are built in layers like onions, with each ...

Astronomers working with the Keck Observatory in Hawaii have obtained spectroscopic data from a supernova discovered by the Zwicky Transient Facility in 2021. The exploding star is 2.2 billion light ...

Did exploding stars help shape human evolution? A bold hypothesis suggests supernovae cooled Earth’s climate and nudged our ...

Astronomers have used a new type of extreme supernova in which a massive star was stripped right "down to the bone" to better ...

Astronomers have observed the calamitous result of a star that picked the wrong dance partner. They have documented what ...

My hypothesis is that remnants of a supernova—an exploding star —had an impact on Earth's past climate, causing global cooling, between 3 million and 2.6 million years ago and that this indirectly ...
