The fourth time scientists have recorded gravity waves
A new gravitational wave was recorded on 14 August.

This week scientists announced that once again registered gravitational waves, “ripples of space-time” caused by the merger of two black holes that are from the us 1.8 billion light-years, reports Rus.Media. A new gravitational wave was recorded on 14 August. This was reported in an article accepted for publication in the journal Physical Review Letters. Briefly about the new detection described in the press release of LIGO.

Earlier there were rumors that the detectors registered the gravity waves from a collision between a neutron star and a black hole or between two neutron stars. However, the rumor was not confirmed, and, as it turned out, a new source of gravitational waves was, as in previous cases, the collision of two black holes: one — mass 31 times the mass of the Sun, the other with a mass exceeding the sun 25 times. When confronted, they formed a black hole with a mass of 53 times solar.

This time, gravitational waves were detected by the detectors LIGO and Virgo. Joined LIGO this summer; it is located near the Italian town of Pisa at the European gravitational Observatory (EGO). In three previous cases, gravity waves were measured by a LIGO Observatory whose detectors are located in Louisiana and Washington (USA). Although Virgo has a lower sensitivity, working together, detectors LIGO and Virgo are better able to track the source of gravitational waves.

Astronomers in the future to improve detectors until the fall of 2018, when they will begin a new stage of observation.
