A distant neutron star has abruptly erupted in brightness, surging to roughly one hundred times its usual output and leaving ...

Do dead stars glow? A strange gravitational phenomenon could be generating enormous amounts of light around neutron stars, new research suggests. When you purchase through links on our site, we may ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars' surface gravities are so intense that the largest "mountains" are only a few ...

A distant neutron star unexpectedly reawakened, unleashing a powerful X-ray surge that may reveal how the universe’s most ...

Astronomers have spent more than a decade watching a compact stellar remnant called P13 slip into near silence and then surge ...

A huge amount of mysterious dark energy is necessary to explain cosmological phenomena, such as the accelerated expansion of the Universe, with Einstein’s theory. But what if dark energy was just an ...

Scientists posit that some dead stars made from the densest material in the known universe, so-called "neutron stars," could act as traps for dark matter particles that smash together at high speeds ...

Astronomers may have discovered the first example of an explosive cosmic event called a "superkilonova," in the form of a ...

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 ...

Neutron stars escape collapse into a black hole thanks to degeneracy pressure produced by their neutrons, which is able to fight the crushing force of gravity. What exactly lies at the heart of a ...

When gas falls onto a compact object, such as a neutron star or black hole, due to its strong gravity (a process called ...
