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 ...

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion light-years from Earth, SN 2024afav was a prime example of a superluminous ...

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.

"What's really exciting is that this is definitive evidence for a magnetar forming as the result of a superluminous supernova core collapse," explained Alex Filippenko, a UC Berkeley distinguished ...

The newborn magnetar, a specific kind of neutron star, actually enhances the brightness of a supernova.

Astronomers have for the first time observed the birth of a magnetar, a highly magnetized, rapidly spinning neutron star, ...

For many years, astronomers have relied on distant supernovae as cosmic beacons to study the universe and test the laws of physics. But while ...

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 observed the birth of one of the most extreme objects in the universe: a magnetar packing the mass of about 500,000 Earths into a sphere only 12 miles wide. A ...

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 ...
