Scientists to Find a Black Hole Swallowing a Neutron Star

Around 900 millions of years ago, a black hole swallowed a dead star. Last week, the remains were found on Earth. If what they found is confirmed to be the remains of a dead star, then the cosmic collision would actually be the first example of a black hole colliding with a neutron star. This can give us a lot of insight with regards to the expansion of the universe.

Back in April, the gravitational wave observatories in the U.S. and Europe have started to look for extreme cosmic events. Ever since then, they have found 23 possible events; however, the latest one is the first of its kind.

This event is called S190814bv, and it was found on Wednesday by two LIGO detectors in the U.S. LIGO stands for Laser Interferometer Gravitational-Wave Observatory. The second one is called Virgo, and it comes from Italy.

Scientists have seen the remains in space-time, and they suggested they appeared due to a black hole swallowing a neutron star.

About neutron stars

A neutron star is created after a supernova explosion. It is very small and dense, and it is made out of neutrons. A normal neutron star has about the 1.5 times the mass of our Sun, and its radius is between 6 and 12 miles.

In these past few months, they have found three other similar events, but it’s possible that they are not actually the same thing. When it comes to  S190814bv, scientists said that the chance that the signal is a false alarm is one-in-trillions-of-years.

Scientists are sure about this entire situation, but they are still cautious until the event is actually confirmed. The collision could have led to two merging black holes. This is still a fantastic discovery for us.
