A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest ...

A neutron star and black hole (GW200105) were detected merging along an unusual oval orbit, challenging theories about how ...

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

Researchers said this event, called GRB 230906A, is likely in a stream of gas located about 4.7 billion light-years from ...

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

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

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" ...

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

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples ...

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 ...

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 ...
