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

As binary neutron stars spiral around each other to merge, their gravitational tidal forces distort each other's shape and structure, potentially revealing clues as to what lies within them.

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.

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

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

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.

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 ...

In 2023, astronomers using NASA’s Chandra X-ray Observatory and Hubble Space Telescope spotted an unusual class of short gamma-ray bursts, whose origin appeared to be the collision of two neutron ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an ...

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 ...
