An image from NASA's Chandra X-ray observatory shows a glowing hand stretching across the cosmos with its palm and fingers ...

The first-ever neutron star merger detected by gravitational waves is still giving off X-rays and scientists aren't sure why.

A 'beautiful effect' predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar -- a neutron star featuring a ...

Mysterious X-rays could be kilonova “afterglow” from 2017 neutron star merger This would mean the two stars "spun down" for a second before collapsing into black hole.

A group of astronomers has found a new way to detect merging neutron stars through the X-rays they give off. Their observation of a merging pair also matches predictions for the birth of a ...

Scientists have reported mysterious X-ray emissions where, more than three years ago, they spotted the first known collision of two neutron stars.

New Mexico Museum of Natural History and Science paleontology curator Thomas Williamson talks about the results of neutron and X-ray scans of a fossilized tyrannosaur skull during a news ...

An international group of researchers performed pendellösung interferometry on silicon using a neutron beam, providing both the highest precision measurements with this technique to date, and a ...

Neutron stars, as their name implies, are made of neutrons, but astrophysicists have not been able to rule out the possibility that they may also contain other exotic forms of matter. Now a team of ...

The X-ray binary system Vela X-1 consists of a neutron star (which contains as much mass as our sun (~1030 kg), but is very compact and has a radius of ~10 km or so, about the size of a small city) ...

An international team has used neutron and X-ray tomography to investigate the dynamic processes that lead to capacity degradation at the electrodes in lithium batteries. Using a new mathematical ...

Neutron stars and black holes that are part of a binary system sometimes emit strongly in the X-ray part of the spectrum. One of the problems is that the accretion disc (a disc of material ...
