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

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.

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" ...

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

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

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

It weighs more than 2 times the mass of our sun, but is only 18 miles wide. Astronomers have discovered the "most massive neutron star ever measured," amassing to more than two times the mass of our ...

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.

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