The oscillation frequencies of two short gamma-ray bursts are the best evidence yet for the formation of “impossible” hypermassive neutron stars that can briefly defy gravity before collapsing to form a black hole. A neutron star forms when a large star runs out of fuel and explodes, leaving behind a super-dense residue that can pack …

Few things can be accomplished in a few hundred milliseconds. Still, for neutron stars seen in the reflections of two gamma-ray bursts, that’s more than enough time to teach us a thing or two about the life, death, and birth of black holes. Sifting through an archive of high-energy flashes in the night sky, astronomers …

A flash of light emitted by the collision of neutron stars has once again upended our understanding of how the Universe works. Analysis of the short burst of gamma rays emitted when the two stars merged revealed that, rather than forming a black hole, as expected, the immediate product of the merger was a highly …
Neutron star collision created a neutron star we thought was too heavy to exist Read More »
Life isn’t really like a box of chocolates, but it seems like something exists. Neutron stars – some of the densest objects in the Universe – can have structures very similar to chocolates, with gooey or hard centers. The kinds of particle configurations that make up these centers are still unknown, but new theoretical work …

Studying the speed of sound revealed that heavy neutron stars have a hard mantle and a soft core, while light neutron stars have a soft mantle and a hard core, much like different chocolate pralines.

An “overweight” neutron star has been observed by astronomers, who say the mysterious object confuses astronomical theories. The hypermassive star was produced by the merger of two smaller neutron stars. Normally, such collisions result in neutron stars so massive that they almost instantly collapse into a black hole under their own gravity. But the latest …
