About 1.3 billion light-years away, two massive black holes had merged, and the resulting shockwave—a gravitational wave—was strong enough for LIGO to detect the moment it washed over Earth. Since ...

The LIGO observatory near Richland has detected the apparent gravitational ripples from a black hole swallowing a neutron star. It could be a scientific first. Just after 2 p.m. Aug. 14, the Hanford ...

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 ...

RICHLAND – The renowned experimental physicist and Nobel laureate whose brainchild resulted in the LIGO observatory at Hanford in Eastern Washington has died. Rainer Weiss, 92, died Aug. 25 in ...

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 ...

Three years ago, a little-known telescope made waves with an incredible discovery, or rather, detected some waves. In 2015, the LIGO telescope became the first to detect gravitational waves, first ...

The Nobel Prize-winning project that hunts for gravitational waves— ripples in space and time—is about to begin the longest and most sensitive observational run to date. The National Science ...

The National Science Foundation (NSF) is awarding Caltech and MIT $20.4 million to upgrade the Laser Interferometer Gravitational-wave Observatory (LIGO) into the Advanced LIGO Plus. Advanced LIGO ...

Just shy of a century after Einstein penned his infamous paper on general relativity scientists finally confirmed a cornerstone of his predictions in 2015 — gravitational waves, little curvatures of ...
