Astronomers used a new technique to measure the spin of five supermassive black holes, located between 8.8 billion and 10.9 billion light-years from Earth, using NASA’s Chandra X-ray Observatory.
The technique involves a combination of a natural phenomenon called a ‘gravitational lens’ and the Chandra equipment to study six quasars, each consisting of a supermassive black hole rapidly consuming matter from its surroundings.

Astronomers have deployed a new technique to capture X-ray images of spinning supermassive black holes billions of light-years away, one of which has reached the ‘point of no return’.
