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

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown mini-galaxy leftover from an ancient cosmic crash. The "collision within a collision" ...

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

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

The violent collision of two neutron stars is providing new insights on how the universe’s heaviest elements were created.

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

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.

NASA missions have discovered evidence of a rare neutron star collision in a tiny, distant galaxy, potentially shedding light ...

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 ...

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

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...
