The discovery of a newborn magnetar inside a distant supernova helps explain why some stellar explosions shine far brighter ...

Astronomers have identified a newborn magnetar as the power source behind SN 2024afav, a superluminous supernova whose brightness far exceeded what standard explosion models could explain. The finding ...

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the ...

An artist's impression of a magnetar with a wobbly accretion disk. (Joseph Farah and Curtis McCully) A never-before-seen 'chirp' in the light of an exploding star has revealed new clues about the ...

A UC Santa Barbara graduate student alongside a local nonprofit research group have advanced the frontiers of physics while ...

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar ...

Magnetars are some of the most extreme objects in the universe. A special class of neutron stars, they are celestial bodies that pack the mass of the Sun in a sphere the size of a city. On top of that ...

Researchers say the "powerful engine" behind superluminous exploding stars had been hidden for years — until a "chirp" from the cosmos helped confirm their link.

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...
