Using the European Space Agency's XMM-Newton and NASA's NuSTAR space telescopes, researchers were observing the black hole as it flung X-rays out into the universe. The black hole is about 10 million times more massive than our sun, and is located in the center of a nearby spiral galaxy called I Zwicky, 1,800 million light-years away from Earth.

After observing a series of bright flares of X-rays, something unprecedented occurred — more flashes that were smaller, later and different "colors" than their predecessors. According to a study published this week in the journal Nature, the "echoes" of light appeared consistent with X-rays reflected from behind the black hole — a very strange place for light to originate.

Abstract
The innermost regions of accretion disks around black holes are strongly irradiated by X-rays that are emitted from a highly variable, compact corona, in the immediate vicinity of the black hole1,2,3. The X-rays that are seen reflected from the disk4, and the time delays, as variations in the X-ray emission echo or ‘reverberate’ off the disk5,6, provide a view of the environment just outside the event horizon. I Zwicky 1 (I Zw 1) is a nearby narrow-line Seyfert 1 galaxy7,8. Previous studies of the reverberation of X-rays from its accretion disk revealed that the corona is composed of two components: an extended, slowly varying component extending over the surface of the inner accretion disk, and a collimated core, with luminosity fluctuations propagating upwards from its base, which dominates the more rapid variability9,10. Here we report observations of X-ray flares emitted from around the supermassive black hole in I Zw 1. X-ray reflection from the accretion disk is detected through a relativistically broadened iron K line and Compton hump in the X-ray emission spectrum. Analysis of the X-ray flares reveals short flashes of photons consistent with the re-emergence of emission from behind the black hole. The energy shifts of these photons identify their origins from different parts of the disk11,12. These are photons that reverberate off the far side of the disk, and are bent around the black hole and magnified by the strong gravitational field. Observing photons bent around the black hole confirms a key prediction of general relativity.

Airman. That’s one wicked looking Black Hole. We are told the object is observed with two sets of x-rays, either collimated or diffuse. We “see” the incredible energies of accreting matter including “reflections” of flaring events from the hole’s opposite side. No energy is being emitted by the black hole itself, why you can even see wisps of structure in front of the hole. It seems the image is “real”, on the other hand, while the image may or may not be an artist’s conception, I believe that all the sophisticated images in astronomy are rendered with respect to specific energy bands, given the specific energy color palette selected, the black hole looks black.

Ok, enough fantasy; these days I always try to interpret things with my charge field hat on. The 10 thousand thousand times larger than our sun object, at almost two billion light years away, of course that’s an artist’s conception. Even if we were close enough to see it, an object of any size cannot behave as a sink for all nearby matter, it must behave as a charged particle, recycling charge. Charge will form vortices entering the object’s poles, which are mainly emitted from the object’s spinning equator. Plumes of energy may correspond to artifacts of direct pole to pole through charge.

Plenty to think about, without the sensational notion of it eventually eating all matter in the universe.
