In a remarkable cosmic event, astronomers have detected a black hole-star merger that has resulted in the longest gamma-ray ...

See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a ...

Astronomers may have recorded the violent birth of one of the weirdest objects our Universe is capable of producing. In a bizarre gamma-ray space explosion whose light reached Earth in 2023, a team ...

Gravity from mountains on rapidly rotating neutron stars produces ripples in space-time known as gravitational waves. The Laser Interferometer Gravitational Wave Observatory (LIGO) searches for such ...

As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the ...

It’s one of the great fun facts of astronomy: most of the elements that make up our bodies, including carbon, oxygen, nitrogen, calcium—pretty much everything, in fact, aside from the H in our ...

A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar. The universe is full of spectacular and ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

Although the first detection of gravitational waves in 2015 gets a lot of press, the detection of GW170817—the first binary neutron star collision—confirms how important gravitational waves likely are ...
