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

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 ...

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

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

After witnessing the massive object undergo a dramatic transformation, a team of astronomers say the star is on the verge of exploding in a powerful supernova, they report in a new study published in ...

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 ...

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

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 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 ...
