For years, astronomers have searched for the origins of ultra-high-energy cosmic rays, the most powerful particles in the universe. These energetic travelers move at nearly the speed of light, packing ...

Neutron stars can have a resounding impact around ... that grew to four to eight times the size of our own sun before exploding in catastrophic supernovae. After one such explosion blows a star's ...

"If a massive star were to explode as a supernova close to the Earth, the results would be devastating for life on Earth," said Nick Wright, an astrophysicist at Keele University in the United Kingdom ...

An international team of astrophysicists from China and Australia has for the first time determined how massive neutron stars ...

These pairs consist of a neutron star devouring up material from a massive ... and teased out some of the elements present in the exploding material, such as nitrogen, oxygen and neon.

Exploding white dwarfs observed by the Palomar ... over which a star can explode in a core-collapse supernova and create a neutron star. If a white dwarf is in a binary system with a "normal ...

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of researchers ...

Scientists believe cosmic rays get spit out by faraway stars exploding (called supernovas). Others could be produced when matter falls into supermassive black holes, from highly magnetized neutron ...

Some become neutron stars while very massive ones become black holes. An exploding supernova throws hot gas into space. Depending on the mass at the start of its life, a supernova will leave ...

"The diversity of ways that white dwarf stars can blow up is much greater than previously expected." There are a lot of ways for dead stars to blow their tops. Astronomers discovered this ...
