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

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

Breakthrough discovery provides new clues about how these celestial bodies - that push the known laws of physics to their limits - find each other.

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

A new theoretical framework shows that tidal forces in inspiraling neutron star pairs can be described through oscillation modes, opening a new path to studying ultra-dense matter using gravitational ...

A faint hum of gravitational waves rippling across the cosmos is now telling scientists what no telescope could show them: the dense, hidden structures buried at the centers of galaxies. A team of ...

Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity ...

The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into ...

Gravity waves are a type of cloud pattern that have little to do with gravity and more to do with the waves. Think of a rock being thrown in a lake or pond and the ripples it creates. As the ripples ...

The loudest collision ever recorded between two black holes has allowed scientists to test Einstein’s theory of general relativity in unprecedented detail, showing that the physicist’s predictions ...
