The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

Neutron stars are just one way of investigating nuclear forces, and simultaneous work is going on at particle accelerators around the world, which act like microscopes to peer inside atomic nuclei.

Neutron stars pack an extremely strong gravitational pull, much greater than Earth's. This gravitational strength is particularly impressive because of the stars' small size. When they are formed ...

See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a ...

Neutron stars are the leftover cores of exploded stars and the densest known material in the universe. A typical neutron star has a mass a few times the mass of the sun, compressed into a region ...

Neutron stars are among the most exotic forms of matter in the universe, consisting almost entirely of neutrons and so dense that a sugar cube of neutron star material would weigh about a billion tons ...

By observing merging neutron stars with three detectors, we located its position on the sky. Telescopes swung into action, leading to the scientific advance of the year.

5. Despite the extremes of neutron stars, researchers still have ways to study them. There are many things we don’t know about neutron stars—including just how many of them are out there, Horowitz ...

Neutron stars are born with temperatures of hundreds of billions, or even a trillion, degrees, and while they do cool, other neutron stars of similar ages have temperatures twice as high — ...

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 ...

Neutron stars as magnifying glasses. The idea of the axion as a dark matter particle is nice, but in physics an idea is only truly nice if it has observable consequences.
