A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown ...

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

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

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

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 ...

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 ...

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

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

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, ...

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 have found the first strong evidence that a neutron star and a black hole merged while travelling in an oval-shaped orbit ...
