Eight concentric rings detected around black hole

A couple of days after astronomers detected light behind a black hole, another discovery is shedding more bits of knowledge into these greatest villains of the universe. Telescopes have now captured a spectacular arrangement of rings around a black hole, which is actively pulling material away from a companion star — about half the mass of the Sun.

The rings were noticed utilizing Nasa’s Chandra X-ray Observatory and Neil Gehrels Swift Observatory around a black hole 7,800 light-years away from Earth. The images have revealed new information about dust located in our Galaxy, that shines in X-rays. The black hole is part of the binary framework called V404 Cygni.

Researchers arrived at the discovery after the Neil Gehrels Swift Observatory initially noticed an eruption of X-rays from V404 Cygni in 2015, that created the high-energy rings from a wonder known as light echoes. These light echoes were delivered when X-rays from the black hole framework ricocheted off of residue mists between V404 Cygni and Earth.

50 observations of the binary framework were done in 2015 between June 30 and August 25 of which Chandra noticed the framework on July 11 and 25.

Astronomers have now consolidated X-rays from Chandra observatory with optical data from the Pan-STARRS telescope in Hawaii that shows the stars in the field of view. The image contains eight separate concentric rings. Each ring is created by X-rays from V404 Cygni flares saw in 2015 that reflect off various residue mists, Nasa said.

Nasa said that observation of the rings revealed new information about the area between the black hole and Earth while revealing insight into the behavior of these massive dark items. The agency maintained that the rings educate us concerning the distances to the mediating dust mists the light ricocheted off, If the cloud is nearer to Earth, the ring appears to be larger and the other way around.

Astronomers also presumed that the residue no doubt contains combinations of graphite and silicate grains and that the thickness of these residue mists doesn’t remain uniform and changes every which way.

Astronomers had as of late noticed splendid X-Ray flares arising out of a supermassive black hole at the focal point of another galaxy, which is nearly 800 million light-years away. The light was detected unintentionally when researchers were contemplating the feature known as the corona.

Telescope got sudden “luminous echoes”, smaller flashes, which were of an unexpected shading in comparison to splendid flashes. Analysis of the X-ray flares revealed short flashes of photons predictable with the reappearance of discharge from behind the black hole. It is already realized that the black hole’s outrageous gravitational field redirects and misshapes light coming from various parts of the plate.
