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

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 ...

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 ...

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 ...

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 ...

Scientists think a gigantic dying star tried to swallow a black hole. It didn't end well for the star, a new study says.

The supernova explosion, designated as SN 2018gv, is found in the spiral galaxy NGC 2525. According to NASA, Hubble began ...

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 ...

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 ...
