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.

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

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 ...

Hubble’s latest image captures the dazzling spiral galaxy NGC 6000, lying 102 million light-years away in Scorpius. Its golden core and bright blue arms reveal a striking contrast between old, cool ...

See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a visual frequency scale (at left) track the steady rise in the frequency of ...

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

The race is on to harness the near-infinite power of nuclear fusion—by building a star on Earth. And scientists are closer ...

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 ...

Researchers think a mysterious signal, dubbed GW190521, could have arrived from a parallel universe after passing through a ...

LIGO's 2015 detection confirmed Einstein's theory and sparked a decade of data. Upgraded LIGOs now detect black hole mergers every three days with precision. New 2025 findings confirmed Hawking’s ...
