For years, physicists have wondered whether one unstable form of copper might act like a traffic jam inside some of the most ...

NASA’s Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station detected a sudden spike of X-rays at about 10:04 p.m. EDT on Aug. 20. The burst was caused by a ...

When a massive star collapses or two neutron stars collide billions of light-years away, the explosion can unleash a brief, ...

On April 28, a supermagnetized stellar remnant known as a magnetar blasted out a simultaneous mix of X-ray and radio signals never observed before. The flare-up included the first fast radio burst ...

The longest gamma-ray burst ever recorded did not behave like a quick cosmic flash. Instead, it burned across the sky for more than seven hours, forcing astronomers to rethink what powers the universe ...

A distant galaxy that lay quiet for decades has suddenly stirred, lighting up in dramatic bursts that have caught astronomers off guard. This unexpected awakening, traced to a black hole at the galaxy ...

A research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has directly measured the masses of two highly unstable atomic nuclei, phosphorus-26 and sulfur-27.

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron stars. The results reveal faster nuclear reactions than previously thought, ...
