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 ...

Volume rendering of density in a simulation of a binary neutron star merger. New research shows that neutrinos created in the hot interface between the merging stars can be briefly trapped and remain ...

Scientists have discovered a new way to probe the interiors of neutron stars by using gravitational waves to turn them into "cosmic tuning forks." The reverberations of such ripples in spacetime could ...

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 ...

A double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although ...

Astronomers may have discovered the first example of an explosive cosmic event called a "superkilonova," in the form of a gravitational wave signal detected on Aug. 18, 2025.

The celestial remnant that lingers after two neutron stars merge isn't like either of its parents. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works ...

Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly ...

Astronomers have spent more than a decade watching a compact stellar remnant called P13 slip into near silence and then surge ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...
