The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

Low-mass stars like our Sun expel their outer layers as a planetary nebula because of what is going on in the star’s core as it ages.

A new study of a star undergoing the throes of a supernova death has revealed that bursts of X-radiation known as fast-X-ray ...

Such core-collapse supernova explosions, powered by neutrinos released from the hot collapsed core, are responsible for the production of most of the intermediate elements, from O to Ti and some ...

Astronomers have traced a mysterious blast of X-rays to a star that, like a cosmic action hero, just refused to die.

Researchers from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences have made significant ...

Astronomers working with the European Southern Observatory's (ESO) Very Large Telescope (VLT) have detected patterns showing ...

Additionally, the core collapse forces magnetic field lines together, thus increasing the strength of the dead stars' magnetic fields.

FXTs are failed gamma-ray bursts, the last signals from dying stars. A decades-long mystery now reveals stellar death is more ...

In a dramatic event called a supernova, the inner core of a heavy star suddenly collapses after it runs out of fuel to burn.

Neutrinos are cosmic tricksters, paradoxically hardly there but lethal to stars significantly more massive than the sun.
