Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects form. These pairs are capable of producing powerful cosmic collisions.

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an ...

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

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

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.

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

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

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

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