Astronomers announced in late June they detected the collision of two black holes, giving them opportunities to study about the mysterious dark objects.
In a SciTech Daily report, scientists observed the merger last 21 May 2019 while using Caltech’s Zwicky Transient Facility (ZTF) located at Palomar Observatory near San Diego, California.
Scientists called the event GW190521g, where they were able to look for light signals from the location where the gravitational wave signal originated.
They also spotted mergers between dense cosmic objects called neutron stars.
In their study published Physical Review Letters, ZTF scientists hypothesized that two black holes are several dozen times bigger than the sun. They were orbiting around a supermassive black hole that is million times larger than the sun.
When the two smaller black holes merged, they later on formed a new larger black hole. This may lead to the shutting off the black hole to another direction, causing it to light up.
Later on, the scientists concluded that the flare is the result of the merger.
According to a New York Times article, black holes are dense objects that even light cannot escape from them. Currently, astronomers know that they are corpses of dead stars, mostly larger than the sun.
