Using NASA's Chandra X-ray Observatory and Neil Gehrels Swift Observatory, astronomers have detected incredibly large rings around a black hole.
Astronomers observed the black hole which is part of the binary system dubbed V404 Cygni that's located around 7,800 light-years from Earth. What the astronomers discovered was that the black hole was drawing material away from its local star, and using Swift Observatory, astronomers discovered a burst of X-rays from V404 Cygni back in 2015.
This burst from the black hole created high-energy rings from a phenomenon known as light echoes, which is when a burst of X-rays bounce off dust clouds between V404 Cygni and Earth. Below is an image that shows the X-rays in light blue overlayed on optical data (stars seen in the image) acquired by the Pan-STARRS telescope in Hawaii. The team of researchers looked at observations made by Swift in 2015, and found that they the distance between each of the intervening dust cloud could be measured with the diameter of each ring.
