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

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 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 ...

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 ...

The death of Betelgeuse will create a celestial spectacle visible from Earth: a point of light as bright as the full moon, even during the day. This video explores the scientific, cultural, and ...

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

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

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

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 ...

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 ...

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