A ghostly set of X-ray rings were found around a black hole with a companion star. These rings are created by light echoes.
(CNN)Black holes are one the universe's ultimate mysteries, hard to even imagine. But thanks to a recently released NASA image, we can visualize one a little bit better now.
Ghostly glowing rings were captured around a black hole by NASA's Chandra X-ray Observatory and Neil Gehrels Swift Observatory. The X-ray images reveal what would otherwise be invisible.
The black hole exists in a binary system with a companion star -- and the black hole's gravity is pulling material away from the star and into a disk around itself.
and it's about 7,800 light-years from Earth. The star has about half the mass of our sun.
The space-based Swift Observatory, launched in 2004, detected an X-ray burst from the binary system in June 2015. This burst actually created energetic rings that are visible in the X-ray images.
Light echoes
The phenomenon that created the rings are light echoes. They were created in this system when the burst of X-rays from the binary system reflected off of dust clouds scattered across space between the V404 Cygni system and Earth.
