This first glimpse into the neutron’s structure marks the beginning of a new chapter in the decades-long quest to solve the spin crisis.

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.

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.

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

Matching the neutron stars' cooling rates to their equation of state could help scientists figure out a quantum theory of gravity.

Astronomers have discovered a neutron star orbiting a mysterious object that, by all accounts, shouldn’t be able to exist. Seemingly invisible in light, and too small to be a black hole, the ...

Ever since neutron stars were discovered, researchers have been using their unusual properties to probe our universe. The superdense remnants of stellar explosions, neutron stars pack a mass ...
