LIGO and Virgo observatories jointly detect black hole collision

LIGO and Virgo observatories jointly detect black hole collision 09/27/2017 12:30 PM EDT In August, detectors on two continents recorded gravitational wave signals from a pair of black holes colliding. This discovery, announced today, is the first observation of gravitational waves by three different detectors, marking a new era of greater insights and improved localization of cosmic events now available through globally networked gravitational-wave observatories. The collision was observed Aug. 14 at 10:30:43 a.m. Coordinated Universal Time (UTC) using the two National ...
