A new study carried out by a group of 32 scientists from 10 countries spotted the smaller black hole of a pair establishing the ‘sight’ of an orbiting blackhole for the first time.
Researchers have already confirmed the theory that there are two black holes at the centre of the four billion light years distant galaxy OJ 287.
The galaxy called OJ 287 is located billion light years away.
In 2021, Researchers also have found indirect evidence that a very massive black hole in OJ 287 is orbiting a giant black hole 100 times its size.
