In a significant breakthrough, astronomers have recently discovered a “ghost star” nestled within the remnants of a supernova ...

Scientists have gotten a rare peek into a dying star, exposing its interior as it exploded. The most massive stars go out with a bang in explosions called supernovas.

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

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

Scientists using the Chandra X-ray telescope have uncovered new details about the famous supernova remnant Cassiopeia A.

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

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 key mystery about Type Ia supernovas is that, in the dominant theory known as D6, a white dwarf would need a companion star ...

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

“Our analysis shows that the blast was sparked by a catastrophic encounter with a black hole companion, and is the strongest ...

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

UMass Amherst physicists believe such an explosion could occur within the next decade, potentially "revolutionizing physics ...
