When two neutron stars collide, they unleash some of the most powerful forces in the universe, creating ripples in spacetime, showers of radiation, and even the building blocks of gold and platinum.

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 ...

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, Swift Observatory and other telescopes. A kilonova is a "the afterglow ...

It isn’t a secret that humanity and everything around us is made of star stuff. But not all stars create elements equally. Sure, regular stars can create the basic elements: helium, carbon, neon, ...

This neutron star merger was golden ... their orbits tighten due to the loss of angular momentum from the system. This leads to the two black holes eventually colliding and merging, sending out a high ...

Two black holes collided 1.3 billion light years from Earth, creating a 'ringing,' which in turn allowed astrophysicists to test some theories. And it turns out, they were all correct.

In a bizarre gamma-ray space explosion whose light reached Earth in 2023, a team led by astronomer Run-Chao Chen of Nanjing ...

The GWTC 4.0 catalog records 128 new gravitational wave signals, revealing mergers of black holes and neutron stars detected by LIGO.

Stephen Hawking was immediately on the phone in 2015 when he learned that the Hanford LIGO observatory in Eastern Washington and its twin observatory in Louisiana had made the first-ever direct ...
