When the core of a massive star collapses, a supernova explosion occurs and the collapsed core forms an extremely compact, rapidly spinning neutron star. Some theories propose that the neutrons ...

Neutrinos are cosmic tricksters, paradoxically hardly there but lethal to stars significantly more massive than the sun.

Observations of the event by several telescopes suggest the faraway star, AT2018cow or "The Cow," collapsed and formed a black hole or neutron star.

A Neutron Star Collapsing Into A Black Hole Might Have Released A Fast Radio Burst A fast radio burst and a gravitational wave event from 2019 seem to be connected in a peculiar way.

Substituting can be a tricky art, especially when stars are involved. When massive stars explode, they can collapse into extremely dense — and mysterious — objects known as neutron stars. But ...

The most massive neutron star ever discovered has been found 3000 light-years away. The tiny star is twice as massive as the Sun but its diameter is mere miles across.

The current generation of gravitational wave detectors could "hear" supernovas over 65 million light-years away, helping scientists determine if a dying star creates a black hole or a neutron star.

The unexpectedly gentle death of a massive star suggests that it was being robbed by a dense companion lurking out of sight.

Scientists have detected a short burst of gamma rays from the collision of two neutron stars that put out more energy in a half-second than the Sun could in its 10-billion-year lifespan ...

An unusually bright star collapse was caught through a telescope last year—now we might know what it was. The mystery of the Cow: This past June, an extremely bright object in the sky created an ...

Mysterious X-rays could be kilonova “afterglow” from 2017 neutron star merger This would mean the two stars "spun down" for a second before collapsing into black hole.

The collision that produced recent gravitational waves may have left behind the biggest neutron star ever seen. But it might have collapsed into a black hole ...
