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

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.

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

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 ...

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 ...

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

WASHINGTON - A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, ...

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 ...

For the first time, we have a front-row seat to one of the most violent events in the universe: a supernova. But there’s a ...

Betelgeuse, the red supergiant anchoring Orion’s left shoulder, will one day run out of fuel and collapse into a supernova ...

Researchers found a magnetic star core acting as a high speed engine to power a record breaking luminous supernova.

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 ...
