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 ...

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.

For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right ...

Maybe music artist Moby was right, and “we are all made of stars.” New research suggests the calcium in our teeth and bones came from star explosions. Researchers from Northwestern University looked ...

Physicists may soon witness a cosmic fireworks show: the explosive death of a primordial black hole. Once thought to be unimaginably rare, new research suggests there’s up to a 90% chance of catching ...

Physicists think we could see such an explosion in the next 10 years - and it would 'revolutionize physics and rewrite the history of the universe'. This artist’s concept takes a fanciful approach to ...
