In A Nutshell Scientists have identified 6,594 solar twins, stars nearly identical to our Sun, in the largest model-driven catalog of its kind ever assembled. Each star was assigned an estimated age, ...

"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 ...

Astronomers have witnessed the birth of a rapidly spinning, highly magnetized neutron star or "magnetar" for the first time. The observation of this event, triggered by the death ...

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

Imagine looking up at the night sky and seeing a star suddenly burst into a blaze of light brighter than anything nearby. A flash so bright that it briefly outshines an entire galaxy before fading ...

More than a year before his recent standoff with the Pentagon, Dario Amodei, the chief executive of Anthropic, published a 15,000-word manifesto describing a glorious AI future. Its title, “Machines ...

The findings confirm a theory first proposed 16 years ago by University of California, Berkeley theoretical astrophysicist Dan Kasen. Kasen and his colleagues hypothesized that at least some ...

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. But some - a small ​fraction - ...

An international research team led by Chinese scientists has discovered new evidence about Type II-P supernovae, suggesting that some of these stellar explosions may originate from merged binary stars ...

NASA’s James Webb Space Telescope reveals new clues about a mysterious cosmic explosion that defies expectations. Researchers are investigating an unusual event in deep space that has left scientists ...

"Almost anyone can get an accommodation. You just have to hire someone to do an assessment and write up a report," one professor said.

Sixteen years ago, theoretical astrophysicists at UC Berkeley and elsewhere proposed that highly magnetized, spinning neutron stars — magnetars — were the power source behind some superluminous ...
