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" ...

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 ...

A fleet of NASA space telescopes has traced a brief flash of gamma rays to a likely collision between two neutron stars, placing the violent event inside a tiny, gas-shrouded galaxy that had escaped ...

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.

Astronomers analyzing the gravitational-wave signal from a 2020 collision between a black hole and a neutron star report ...
