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

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.

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

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

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.

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar ...

Astronomers may have found an exciting new clue about dark energy—the mysterious force driving the universe’s accelerating expansion. They discovered an extraordinarily bright supernova from more than ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that ...

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

One of the largest known stars in the cosmos is poised for catastrophe. After witnessing the massive object undergo a dramatic transformation, a team of astronomers say the star is on the verge of ...

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