The European southern Observatory (ESO) reports that for the first time in history, astronomers observed gravitational waves and light (electromagnetic radiation) generated by the same cosmic event.
Gravitational waves are predicted by General relativity and other theories of gravity. This changes the gravitational field that propagate like waves.
It is reported that on 17 August 2017 was first observed gravitational-wave and electromagnetic signals, those born during the merger of two neutron stars. This cosmic catastrophe was recorded by the Observatory, LIGO (Laser Interferometric Gravitational-Wave Observatory) in the United States, as well as Cosmic gamma-ray telescope NASA Fermi (Fermi Gamma-ray Space Telescope) gamma and astrophysical laboratory ESA INTEGRAL (INTErnational Gamma-Ray Astrophysics Laboratory).
The result was a cosmic catastrophe, which has long been predicted by theorists and was called “Bulanovoj” in the space are ejected heavy elements such as gold and platinum. In addition, the most compelling to date, evidence that short gamma-ray bursts also caused by the mergers of neutron stars.
This is the fifth detection of gravitational waves has received the designation GW170817. Observations showed that the source of the gravitational signal is about 130 million light-years from Earth on the outskirts of a bright elliptical galaxy NGC 4993. Thus, it is the nearest to us of all detected sources of gravitational waves and one of the closest ever observed sources of gamma-ray bursts.
“It is very rare that a scientist had to witness the beginning of a new era in science. This is one of those cases!“, — the researchers say.
