Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

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 ...

Astronomers have detected a neutron star collision in an unexpected place, deep within a tiny, faint galaxy. Located about ...

A neutron star and black hole were detected merging along an unusual oval orbit, challenging long-held theories about how these systems form.

Astronomers analyzing the gravitational-wave signal from a 2020 collision between a black hole and a neutron star report evidence that the pair spiraled together on an oval-shaped orbit, rather than a ...

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.
