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

The four gravitational wave observatories around the world have been busy lately, revealing hundreds of detections. These ...

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 ...

We all know how weird black holes are, but did you know there is another type of star that is just as strange? Welcome to the universe of neutron stars.

Scientists believe this long stream of gas may have formed when several galaxies collided millions of years ago.

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.

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 ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...
