Space is an endless void of mysterious unknowns, and one particularly alluring enigma concerns the point at which neutron stars take on too much mass and collapse into black holes as a result.

Astronomers have weighed a neutron star with nearly double the mass of the sun, the heaviest yet found. A mass that high rules out many theories that these ultradense remnants of supernova explosions ...

A: The quick answer to your question is yes, they can gain matter. However, only a small fraction of neutron stars can gain mass — those in binary systems, where mass is transferred from the companion ...

Neutron stars can be considerably more massive than previously believed, and it is more difficult to form black holes, according to new research developed by using the Arecibo Observatory in Arecibo, ...

What's in a neutron star? Well, neutrons, obviously. However, despite the deceptively simple label, the inner working of neutron stars remain elusive, partly because their basic properties, such as ...

How do you weigh a star? If two stars orbit each other, then we can determine their masses by their orbits. Since each star pulls gravitationally on the other, the size of their orbits and the speed ...

A small star named M82 X-2 breaks physical barriers, as NASA's NuSTAR confirms it shines 10 million times brighter than the ...

New insights into the properties of neutron stars have come from two independent analyses of gravitational waves from the GW170817 neutron-star merger. The work was done by teams led by Farrukh ...

These collapsed stellar cores pack the mass of the Sun into a city-sized sphere, warping space and time.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Unlike most of the others, however, this one might be the ...

Using a pioneering method, researchers have found a neutron star of about 2.3 Solar masses -- one of the most massive ever detected. Neutron stars (often called pulsars) are stellar remnants that have ...
