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

The mystery of superluminous supernovae has finally been solved, as researchers have conclusively linked these cosmic phenomena to magnetars.

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 ...

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 ...
