On Earth recorded, “the universal roar” produced 870 million years ago
Edition Today Lifestyle
Universal indignation was named S190814bv
The gravitational wave detector LIGO recorded a strange disturbance in space-time that were not previously detected. At first scientists were confused, calling the surge a “universal roar” – so powerful was this event called S190814bv. Wave analysis confirmed the surprising fact, which has caused excitement among astronomers around the world. Reports Gizmodo.

Scientists have identified a strange disturbance in the space-time, called gravitational waves, as the merger of neutron stars and black holes with a probability of 99%. Previously, the detector recorded a dozen mergers exclusively black holes, but the absorption of the neutron star detected for the first time.
Astronomers have discovered a strange flash in the center of our Galaxy
Detector of gravitational waves has announced that at least one of the objects which produced S190814bv, hit the “mass gap” — the area covering the range from 3 to 5 solar masses, which is apparently devoid of black holes and neutron stars. All known black holes weigh more than five solar masses, while all known neutron stars born from the lighter stars, which are unable to become black holes, weigh about 1.5-2 solar masses. Detection of an object in the gap of the masses was a surprise for collaboration LIGO-Virgo, which can modify the theoretical boundary separating the heaviest neutron stars from the lightest of black holes.
“My jaw dropped when I double-checked,” says Geoffrey Lovelace of California state University working in the LIGO (Laser interferometric gravitational-wave Observatory).
Signals from space: astronomers have caught 8 mysterious messages
“It was something beyond theory. The event, which we’ve been waiting for all this time,” says James Lattimer, Professor of astronomy at the University of new York and innovative nuclear astrophysicist who showed in his thesis in 1976 that mergers of neutron stars and black holes may be spraying in space, such heavy elements like gold and uranium.
The wave was detected by LIGO in the US and the Virgo Observatory in Italy on 14 August. Automatically obtained data showed that the perturbation of space-time is the result of an unprecedented merger of a pair of bodies, too light for the formation of gravity waves that caused astronomers to look for additional electromagnetic radiation from this event. Subsequent analysis classified the signal as a collision between a black hole and a neutron star — a stellar remnant in which the gravity squeeze the entire mass of the Sun into a ball the size of a small city with a diameter of approximately 20 kilometers.
Curve and twisted: astronomers showed the shape of our galaxy
The event that caused the crashing of universal scale, occurred about 870 million years ago, when two dead stars become one. Merging shook the fabric of the cosmos gravitational wave that has swept through the Land and went through three pairs of carefully calibrated sensors designed to detect them.
It was the first confirmed event, and after the collision of two black holes and the merger of two neutron stars into a black hole — the third type of collisions detected by the gravitational waves. If the current analysis will remain in force, this event, dubbed S190814bv, will mark the beginning of a new era of astrophysical research, with implications for how researchers understand the General theory of relativity, the death of stars and the behavior of extreme forms of matter.
We will remind that earlier scientists called the Earth’s least habitable. Also recently, scientists said that astronomers have caught a 8 mysterious messages from deep space.
