A spectacular cosmic event’s observation was announced by scientists in October 2017. This event was about how two extremely solid starts merge at 130 million light-years away. This was the first such phenomenon to be experienced.
What kind of phenomenon is this?
As technology never stops evolving, a narrow jet of particles was discovered by scientists using radio telescopes, and it occurs because the event we talked about it moving almost as fast as the light and travels through interstellar space.
The bodies of this merging pair have an extreme density which makes them neutron stars: if it were to weigh a teaspoon of it on Earth, it would be a billion tons.
The Virgo and Laser Interferometer Gravitational Observatory (LIGO) experiment on Earth has picked up a gravitational wave it created beside the fact that you can visually observe the first merger.
As a definition of gravitational waves, those are ripples in space-time and were predicted for the first time in 1916 by Albert Einstein in the general theory of relativity. Until 2015 there were not detected because these highly sensitive detectors were not available, but they have finally picked up the two merging black holes’ wave.
After the two neutron start merged, they suffered a collapse into a black hole which is a unique object which such a gravitational strength that nothing can escape from it. Another effect of this event is that it created a disk which spins very fast and stays to the cosmic belch’s source which was observed by astronomers. It looks like a GRB or a short gamma-ray burst. Beside that is also formed something like a cocoon.
According to the paper’s lead author who was also published in Nature “What creates these jets isn’t known” and an astronomer at the National Radio Astronomy Observatory (NRAO) and Caltech, Kunal Mooley agrees with him.
