The Laser Interferometer Space Antenna (LISA) is a planned space probe to detect and measure gravitational waves [2] —tiny ripples in the fabric of spacetime—from astronomical sources. [3] LISA will be the first dedicated space-based gravitational-wave observatory. It aims to measure gravitational waves directly by using laser interferometry.
Scientists said on Thursday they have for the first time detected gravitational waves, ripples in space and time hypothesized by Einstein a century ago. Einstein's gravitational waves detected in ...
Detector noise curves for Initial and Advanced LIGO as a function of frequency. They lie above the bands for space-borne detectors like the evolved Laser Interferometer Space Antenna (eLISA) and pulsar timing arrays such as the European Pulsar Timing Array (EPTA). The characteristic strains of potential astrophysical sources are also shown.
The European Space Agency has selected a gravitational-wave mission for its L3 mission, due to launch 2034, the current concept is the evolved Laser Interferometer Space Antenna (eLISA). [20] Also in development is the Japanese Deci-hertz Interferometer Gravitational wave Observatory (DECIGO).
Three U.S. scientists won the 2017 Nobel prize for physics in October for pioneering a new era of astronomy by detecting gravitational waves, ripples in space and time predicted by Albert Einstein ...
The blue lines are gravitational waves, ripples in time and space, which is how astronomers detected the merger, and orange and red areas indicate parts of the neutron star being stripped away.
This type of instrument was the first type of gravitational-wave detector. Strains in space due to an incident gravitational wave excite the body's resonant frequency and could thus be amplified to detectable levels. Conceivably, a nearby supernova might be strong enough to be seen without resonant amplification.
The Hanford observatory uses laser interferometry to measure minute ripples in space-time caused by gravitational waves passing through Earth from cataclysmic cosmic events such as colliding ...
