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

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

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 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" ...

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

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

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.

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 ...

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 ...

When the remnants of two stars collide, their union can launch a dazzling jet of high energy matter. A new computer simulation reveals how the merger, which forms a black hole, emits that bright beam, ...
