Scientists Catch Another Gravitational Wave, And They Know Where It Came From

Last year, physicists made history by observing the first-ever gravitational wave. Their discovery confirmed Albert Einstein’s century-old theory of gravity and capped decades of effort to build an instrument sensitive enough to catch these ripples in spacetime.

Since then, researchers working at the government-funded Laser Interferometer Gravitational Wave Observatory (LIGO) — twin detectors in Louisiana and Washington State — have caught several more gravitational waves.
