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

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

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.

For many years, astronomers have relied on distant supernovae as cosmic beacons to study the universe and test the laws of physics. But while ...

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 ...

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...
