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. The ...

When black holes collide, they do not all seem to follow the same cosmic script. A sweeping new analysis of the latest ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the maelstrom of interacting magnetic structures around city-sized neutron stars in ...

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 ...

Multi-messenger astronomy of neutron star mergers unites gravitational-wave detections, electromagnetic observations across the spectrum and potential neutrino and cosmic-ray signals to probe the ...

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 ...

Artist’s impression of an eccentric neutron star–black hole binary. The neutron star’s path is shown in blue and the black hole’s motion in orange as the two objects orbit each other. The eccentricity ...
