Scientists in Chile have announced that they have discovered the closest pair of supermassive black holes to Earth.
In Chile, astronomers have observed the closest pair of supermassive black holes ever to Earth, with the help of a giant telescope operated by the European Southern Observatory.
The black holes in question are reported to be 1,600 light-years away from each other and 89 million light-years from Earth.
Scientists also confirmed that the distance between the black hole pair will decrease over time and turn into a single black hole.
It is reported that one of the pairs of black holes is located in a galaxy in the constellation Aquarius (NGC 7727), and it has a mass of 154 million times the mass of the Sun.
The researchers said they calculated the mass of black holes by looking at how the force of gravity affects the movement of stars around them.
Experts reported that for the first time a pair of supermassive black holes was calculated in this way, and they reported that the number of other known supermassive black holes could increase by 30 percent.
