Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts.

When a massive star runs out of fuel, it collapses and explodes in a supernova. If the star is 7 to 19 times the mass of our Sun, it leaves behind a neutron star.

Astronomers have used a range of telescopes, including Hubble, to watch as particles dance around a neutron star collision that created the smallest black hole ever seen.

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 ...

New research suggests that colliding neutron stars can briefly "trap" ghostly particles called neutrinos, which could reveal new secrets about some of space's most extreme events.

Smash-ups between dead neutron stars create and trap ultrahot ghost particles called neutrinos, new simulations have shown. The discovery could help us better understand how elements like gold are ...

Scientists said that the inside of neutron stars might contain a form of ultradense matter not found elsewhere in the cosmos.

Neutron stars might be the key to understanding dark matter. Physicists from the ARC Centre of Excellence for Dark Matter Particle Physics, led by the University of Melbourne, have made a significant ...

The youngest neutron star detected so far turned 37 years old last week. To celebrate, James Webb Space Telescope has finally found the most direct evidence of it, hiding among the remains of the ...

Image shows evidence for a neutron star following a stellar explosion called Supernova 1987A in the Large Magellanic Cloud, a dwarf galaxy neighboring our Milky Way, in this handout combination of ...
