The pair of black superholes is 400 million light years from Earth

Two super black holes revolve around each other, only 400 million light-years from Earth discovered by scientists.

Scientists at the University of Pune, India and the Rochester Institute of Technology, USA, announced the discovery of a pair of black superholes within NGC 7674 in research published in Nature Astronomy on September 18, according to Popular. Mechanics.

The distance of 400 million light years is thousands of times the diameter of the Milky Way and dozens of times the distance from the Milky Way to the nearest large galaxy Andromeda.

Each supermassive black pair in the pair weighs about a million times the mass of the Sun. They are only a light-year apart, this is the smallest distance between two orbiting black holes that have been discovered, except for the two black holes that collided with the LIGO observatory in the US in 2016.

Currently, these two supermassive black holes take 100,000 years to orbit each other. Gravitational waves are constantly being created to reduce their energy. For the next millions of years, two super black holes will inch into each other until the time of the collision.
