After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Unlike light ...

It has been three years since the Laser Interferometer Gravitational-Wave Observatory (LIGO) shut down, starting a long hiatus from searching the universe for gravitational waves. Now, though, the ...

Detector engineers Hugh Radkins (foreground) and Betsy Weaver (background) take up positions inside the vacuum system of the detector at LIGO Hanford Observatory to perform the hardware upgrades ...

Two merging black holes, each roughly 30 times the mass of the sun, in a computer simulation. Gravitational wave observatories, such as the Laser Interferometer Gravitational-Wave Observatory (LIGO), ...

After a three-year hiatus, scientists in the US have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Unlike light waves ...

The best place to observe the stars is among them, which is why Hubble and the James Webb Space Telescope have been deployed outside Earth's murky atmosphere. At least, that's the case when you're ...

On May 24, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) began an 18-month campaign to detect the most distant collisions between black holes and neutron stars ever ...

Later this year a new detector is set to begin hunting for gravitational waves – ripples in the very fabric of spacetime. The Kamioka Gravitational-wave Detector (KAGRA) in Japan will join the Laser ...

A fourth gravitational wave detector, this one in Gifu Prefecture, Japan, will join the global search for cosmic events that cause ripples in spacetime, beginning this December. The Kamioka ...

Colliding black holes and neutron stars create ripples in spacetime, called gravitational waves. These were "heard" for the first time in September 2015. On Monday, a pair of gravitational-wave ...
