New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the ...

Astronomers have used an X-ray spacecraft called XRISM to observe powerful winds blowing from a neutron star — the findings could be a "game changer" for physics. The team discovered unexpected ...

See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a visual frequency scale (at left) track the steady rise in the frequency of ...
