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 ...

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 ...

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

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 ...

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

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 ...

Astronomers have identified the first clear evidence of a magnetar forming during a superluminous supernova, offering new insight into some of the brightest explosions in the universe.

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 ...

Far beyond the Milky Way, in a nearby satellite galaxy, a giant star has been shifting in a way astronomers did not expect. The star, known as WOH G64.
