The final dance of a black hole and a neutron star before their ultimate merger has been revealed, according to new research.

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

The four gravitational wave observatories around the world have been busy lately, revealing hundreds of detections. These provide statistical insights into the collisions between the incredibly ...

The mystery of superluminous supernovae has finally been solved, as researchers have conclusively linked these cosmic phenomena to magnetars.

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

A new theoretical framework shows that tidal forces in inspiraling neutron star pairs can be described through oscillation modes, opening a new path to studying ultra-dense matter using gravitational ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an ...

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature ...

Add Yahoo as a preferred source to see more of our stories on Google. This artist's concepts shows a hypothesized event known as a superkilonova. A massive star explodes in a supernova (left), which ...

Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint dwarf galaxy embedded in a vast stream of ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the ...
