Gravitational-Wave detected by LIGO and Virgo - The Incredible Truth

LIGO and VIRGO Announce Four new Gravitational-Wave Detections from the Black Hole Mergers

Four new Gravitational waves were detected from the Black hole mergers. The position of the binary black holes was spotted 2.5 billion light-years from the Earth, located by LIGO and VIRGO observatories. They announce four new Gravitational –wave detections. They identified the signals coming from a precision of 39 square degrees.

Gravitational Waves : Gravitational waves are 'ripples' in the fabric of space-time caused by some of the most violent and energetic or massive processes in the Universe. 

The US based LIGO (Laser Interferometer Gravitational-Wave Observatory) and Europe based VIRGO gravitational-wave detectors have recorded gravitational waves from a total of 10 black hole mergers and one merger of neutron stars. The new signals are known as GW170729, GW170809, GW170818, and GW170823. The nomenclature of these waves has the format of “Gravitational Wave Date (YY/MM/DD)”. These signal are also called the gravitational-wave events.

GW170729 was detected in the second observing run on July 29, 2017. It was the most massive and distant gravitational wave source ever observed. GW170814 was the first binary black hole merger measured by the three detector network. GW170814 represented the first time that gravitational waves were ever observed from the merger of a binary neutron star system.
