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 ...

X-ray scanning revealed the embedded crocodile (3-D digital reconstruction, shown). But it took neutron scanning to discover dinosaur bones (red) in the croc’s belly.

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

NASA has unveiled a breathtaking new image showing what appears to be a massive “cosmic hand” stretching across 150 ...

The fabric of spacetime can be distorted by immense gravity, and black holes show the most extreme version of this, where density appears infinite and physics begins to collapse.

The first-ever neutron star merger detected by gravitational waves is still giving off X-rays and scientists aren't sure why. Jackson Ryan was CNET's science editor, and a multiple award-winning ...

Basking in the afterglow 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.

Neutron star's X-rays reveal 'photon metamorphosis' Date: May 4, 2023 Source: Cornell University Summary: A 'beautiful effect' predicted by quantum electrodynamics (QED) can explain the puzzling ...

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

The neutron star rotates once every ~283 s and shines brightly in X-rays by accreting gas from the stellar wind emanating from the massive companion star. The captured gas falls in the strong ...

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 ...

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 ...
