A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

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

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 analyzing the gravitational-wave event known as GW200105 report evidence that a black hole and neutron star ...

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

Astronomers have detected an Earth-size planet candidate orbiting a nearby star once a year, making it a promising target for ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an oval path rather than a perfect circle just before they merged. This discovery ...

A new study has found that an asteroid NASA used for target practice a few years ago was nudged into a slightly different ...

NASA's DART mission didn’t just change the orbit of Dimorphos, the asteroid it hit. It changed the orbit of the larger ...
