A black hole swallowed up a dead star, about 900 million years ago, Last week, the resulting ripples in space and time were subsequently discovered on Earth.
The cosmic collision probably the first example of a black hole colliding with a neutron star, perhaps providing new insights into the expansion of the universe, the scientist stated.
In April, gravitational wave observatories in the United States, and Europe reignited a search for ultimate cosmic events. Astronomers have detected 23 possible events, but the latest one could be the first of its own.
The event, known as S190814bv, was detected on Wednesday by two LIGO detectors within the United States Laser Interferometer Gravitational-Wave Observatory and the Virgo detector in Italy. Scientists studied ripples in space-time, recommending they could have occurred because of a black hole swallowing a neutron star.
A neutron star is created a supernova explosion and is very small and dense, consisting of tightly-packed neutrons. A standard neutron star has about 1.5 times the mass of the sun, however a radius around 6 and 12 miles.
In the past few months ago, three other same events have been discovered, but possible they were “noise” rather than real events. Within the case of S190814bv, scientists stated the chance the signal can be false alarm is one in trillions of years.
While this is the confident scientists have been, they’re still urging caution till the event is confirmed. As an example, the collision could have been two merging black holes yet an exciting discovery of a black hole lighter than any seen before.
“There’s the slight however intriguing risk that the swallowed object was a mild black hole much lighter than any other black hole we know about within the Universe,” stated by Professor Susan Scott. “That would be a very awesome consolation prize.”
Astronomers are working to confirm the size of the two objects that crashed together to form the cosmic ripples. They’re also scanning the area with telescopes the place they believe the occasion occurred, searching for the light possibly radiated by the merger.
