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

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 ...

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

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 ...

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

Gamma ray bursts are the most powerful explosions in the universe, unleashing as much energy as the Sun will in its 10 ...

Around 11,300 years ago, a massive star teetered on the precipice of annihilation. It pulsed with energy as it expelled its ...

A rare supernova let scientists glimpse a star's interior, revealing a dense silicon-sulphur shell and unexpected helium that should have vanished earlier. (Nanowerk News) An exploding star has given ...

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 ...

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