The four gravitational wave observatories around the world have been busy lately, revealing hundreds of detections. These ...

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 believe this long stream of gas may have formed when several galaxies collided millions of years ago.

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

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.

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

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

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

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an ...
