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

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 ...

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 ...

Scientists have discovered what could be the largest neutron star on record, according to new research. Neutron stars are among the strangest objects in the sky. They’re wildly compact: just a few ...

New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the maelstrom of interacting magnetic structures around city-sized neutron stars in ...

Massive merger: illustration of gravitational waves from a neutron-star merger Data from the recent observation of gravitational waves from the merger of a binary neutron star have been used to place ...

Neutron stars are the remnants of violent supernovae, all that’s left behind when a star tens of times the mass of our Sun ends its nuclear fuel-burning life. These extreme objects pack more mass than ...

A new study showing how the explosion of a stripped massive star in a supernova can lead to the formation of a heavy neutron star or a light black hole resolves one of the most challenging puzzles to ...
