Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of ...

This study shows that the universe itself can push the boundaries of physics in ways laboratory tests cannot. By ruling out ...

Physicists have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter that ...

"It is fascinating to concretely see how each new neutron-star observation enables us to deduce the properties of neutron-star matter with increasing precision." When you purchase through links on our ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars are the leftover cores of exploded stars and the densest known material in the ...

Creating a neutron star Before you can get this ideal cosmic laboratory, a star first has to die. The end of a star’s life depends largely on its mass. Unremarkable stars like the Sun go out with a ...

We take a journey to the center of a neutron star, a place where matter exists in states. We’ve traveled to lots of weird places on this show - from the interiors of black holes to the time before the ...

A neutron star is 2 solar masses compressed into a ball only 12 kilometers wide. Its surface gravity is so immense it compresses atoms and molecules into raw nuclei and squeezes electrons into protons ...

The heaviest neutron star ever detected is shredding its companion while spinning on its axis over 700 times per second. The neutron star, known as PSR J0952-0607, was discovered in 2017 about 3,000 ...
