The violent merger of two neutron stars is thought to involve three main energy-transfer processes, shown in this diagram, that give rise to the different types of radiation seen by astronomers, ...

Our readers agree that in the unlikely event you were able to approach a neutron star, it would look very smooth and bright ...

Physicists have measured the microscopically thin skin of neutrons enclosing the insides of atoms of lead for the first time, finding that it's thicker than expected. The discovery could help to ...

In a recent breakthrough, the XRISM mission has uncovered a puzzling cosmic phenomenon—a slow, dense wind emanating from the neutron star GX13+1. This unexpected discovery, detailed in a study ...

Astronomers have added a new species to the neutron star zoo, showcasing the wide diversity among the compact magnetic remains of dead, once-massive stars. While it’s an oddball, some of this newfound ...

Imagine that a massive star, one far bigger than our own sun, has died. First there is a spectacular explosion, followed by whatever remains. Sometimes it is a black hole, which can be fascinating in ...

It weighs more than 2 times the mass of our sun, but is only 18 miles wide. Astronomers have discovered the "most massive neutron star ever measured," amassing to more than two times the mass of our ...

XRISM found a slow, thick wind from a neutron star, pointing to temperature as the key driver of cosmic wind behavior. The ...

"If axion clouds, and thereby axions, are discovered, this would be a massive step toward solving the dark matter problem." When you purchase through links on our site, we may earn an affiliate ...

Neutron stars are very small and dense stars, where roughly half a million earth masses of material are squeezed into a city-sized volume with a radius of 10 km. They are mostly composed of neutrons ...
