On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to ...

Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

Researchers have demonstrated a new, unsupervised machine learning approach to find new patterns in the auxiliary channel data of the Laser Interferometer Gravitational-Wave Observatory. Finding ...

After a prolonged absence from the gravitational-wave-detection scene, the massive LIGO project is back up and running. The Laser Interferometer Gravitational-Wave Observatory (LIGO) works in ...

The LIGO Hanford Observatory near Richland is expected to detect 60% more cataclysmic cosmic events — like colliding neutron stars and black holes — thanks to a quantum limit breakthrough. Since the ...

Could LIGO find alien spacecraft accelerating to near light speed? The gravitational wave detector LIGO has made hugely important discoveries. But what else might be hiding in the ripples’ of ...

The Indian government has granted the final approvals necessary for construction to begin on LIGO-India, a nearly identical version of the twin LIGO (Laser Interferometer Gravitational-Wave ...

Trump budget proposal seeks to close one of two U.S. LIGO observatories by 2026. LIGO facilities detected first gravitational waves and advanced multi-messenger astronomy. Proposed closure risks ...

Long ago, in a galaxy far away, two black holes danced around each other, drawing ever closer until they ended in a cosmic collision that sent ripples through the fabric of spacetime. These ...

This artwork imagines the ultimate front-row seat for GW250114, a powerful collision between two black holes observed in gravitational waves by the US National Science Foundation LIGO. It depicts the ...
