They were too big and too far away to exist by the rules. Now, using the James Webb Space Telescope (JWST), an international team of astronomers has finally cracked the chemical code of these distant ...

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 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 ...

"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 ...

Italian astronomers have performed extensive spectroscopic monitoring of a recently discovered nova known as Vulpeculae 2024, ...

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 ...

Researchers say the "powerful engine" behind superluminous exploding stars had been hidden for years — until a "chirp" from the cosmos helped confirm their link.

A UC Santa Barbara graduate student alongside a local nonprofit research group have advanced the frontiers of physics while ...

WASHINGTON, March 11 (Reuters) - A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, usually about a billion times more luminous than the sun.

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 ...

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the supernova known as SN 2024afav settled into something stranger. Its brightness ...
