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 ...

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

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 ...

These provide statistical insights into the collisions between the incredibly compact objects that cause them, whether neutron stars or black holes. The new detections have also allowed us to find ...

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

Most gamma-ray bursts—the brightest, most powerful explosions in the universe—are tracked back to the deaths of massive stars. But a new discovery suggests that such enormous explosions can come from ...

Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

Neutron star collision in merging galaxies reveals how cosmic destruction forges heavy elements like gold, offering clues to the universe's chemical evolution.

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