Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.

Astronomers have for the first time observed the birth of a magnetar, a highly magnetized, rapidly spinning neutron star, directly linked to some of the universe’s brightest exploding stars. This ...

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

WASHINGTON, March 11 (Reuters) - A supernova - the explosion marking the end of a massive star's life - is one of the ...

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

One of the largest known stars in the cosmos is poised for catastrophe. After witnessing the massive object undergo a ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

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 ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that can trigger these events.

NASA’s James Webb Space Telescope captured the first published detection of a supernova progenitor in galaxy NGC 1637, ...

This violent fate is rare: fewer than about 1% of stars are big enough to end their lives this way. Indeed, these dramatic explosions only occur in so-called “massive stars”. These are stars with a ...
