On January 14, 2025, a pair of black holes with nearly identical masses crashed together roughly 1.2 billion light-years away ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two ...

Ripples in space-time from a pair of merging black holes have been recorded in unprecedented detail, enabling physicists to test predictions of general relativity ...

In 2019, LIGO and Virgo recorded something truly bizarre – a gravitational wave event less than a tenth of a second in duration. Compared to the drawn-out chirps of black hole binaries on decaying ...

After detection, there's a small window of time within which follow-up, light-based astronomy observations can be made. When you purchase through links on our site, we may earn an affiliate commission ...

The results are included in a new paper from the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the VIRGO gravitational-wave detector, which presents analysis of 10 stellar-mass binary ...

EVANSTON, Ill. (CBS) -- A Northwestern University astrophysicist is part of an international team of scientists creating a gravitational wave detector system that will eventually be launched into ...

The glow from this titanic collision, shining within the galaxy NGC 4993 is at a distance of 130 million light-years away. On August 17, 2017, the Laser Interferometer Gravitational-Wave Observatory ...

Could it be that human existence depends on gravitational waves? Some key elements in our biological makeup may come from astrophysical events that occur because gravitational waves exist, a research ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...
