What's the link between an exploding star, climate change and human evolution? Francis Thackeray, who has researched ancient ...

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

Francis Thackeray has received funding from the National Research Foundation. Global cooling that happened millions of years ago was thought to be the result of ocean currents. He suggests instead it ...

Artist's impression of a supernova. By ESO/M. Kornmesser/Wikimedia Commons, CC BY My hypothesis is that remnants of a supernova – an exploding star – had an impact on the Earth’s past climate, causing ...

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 ...

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

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

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 ...

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 ...
