NASA's Swift reveals a black hole bull's-eye
Rings of X-ray light centered on V404 Cygni, a binary system containing an erupting black hole (dot at center), were imaged by the X-ray Telescope aboard NASA's Swift satellite from June 30 to July 4. A narrow gap splits the middle ring in two. Color indicates the energy of the X-rays, with red representing the lowest (800 to 1,500 electron volts, eV), green for medium (1,500 to 2,500 eV), and the most energetic (2,500 to 5,000 eV) shown in blue. For comparison, visible light has energies ranging from about 2 to 3 eV. The dark lines running diagonally through the image are artifacts of the imaging system.

What looks like a shooting target is actually an image of nested rings of X-ray light centered on an erupting black hole. On June 15, NASA's Swift satellite detected the start of a new outburst from V404 Cygni, where a black hole and a sun-like star orbit each other. Since then, astronomers around the world have been monitoring the ongoing light show.

On June 30, a team led by Andrew Beardmore at the University of Leicester, U.K., imaged the system using the X-ray Telescope aboard Swift, revealing a series concentric rings extending about one-third the apparent size of a full moon. A movie made by combining additional observations acquired on July 2 and 4 shows the expansion and gradual fading of the rings.

Astronomers say the rings result from an "echo" of X-ray light. The black hole's flares emit X-rays in all directions. Dust layers reflect some of these X-rays back to us, but the light travels a longer distance and reaches us slightly later than light traveling a more direct path. The time delay creates the light echo, forming rings that expand with time.

Detailed analysis of the expanding rings shows that they all originate from a large flare that occurred on June 26 at 1:40 p.m. EDT. There are multiple rings because there are multiple reflecting dust layers between 4,000 and 7,000 light-years away from us. Regular monitoring of the rings and how they change as the eruption continues will allow astronomers to better understand their nature.

"The flexible planning of Swift observations has given us the best dust-scattered X-ray ring images ever seen," Beardmore said. "With these observations we can make a detailed study of the normally invisible interstellar dust in the direction of this black hole."

V404 Cygni is located about 8,000 light-years away. Every couple of decades the black hole fires up in an outburst of high-energy light. Its previous eruption ended in 1989.

The investigating team includes scientists from the Universities of Leicester, Southampton, and Oxford in the U.K., the University of Alberta in Canada, and the European Space Agency in Spain.

Swift was launched in November 2004 and is managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland. Goddard operates the spacecraft in collaboration with Penn State University in University Park, Pennsylvania, the Los Alamos National Laboratory in New Mexico and Orbital Sciences Corp. in Dulles, Virginia. International collaborators are located in the United Kingdom and Italy. The mission includes contributions from Germany and Japan.

"RINGS" huh! All the galaxies have long term "RING" or shell like structure! GR and Big Bang cosmology has nothing to say about them! "Gravitational wave" will not hold water, because it has to move at about the speed of light or may be more.

There are multiple rings because there are multiple reflecting dust layers
caused by multiple events over time, you ignorant sot.

The ring like structures in the cosmic bodies like galaxies, clusters, stars, the solar systems, even recent supernovas like supernova 1987A etc, can be explained by a Qualitative Graviton-Orbital theory ( a proposed new quantum dynamical theory of gravity), as explained in the above reference in the chapter "Gravity – An Intrinsic Property of Matter!" Gravitons as bosons can collect in unlimited number and the force of gravity is due to the exchange of virtual boson particles, much like any other forces of nature. This is also the reason why gravity is always an attractive force, at least in the finite range.

In this scheme, gravitons (as bosons) are distributed in quantized formation around matter particles such as the dense core of galaxies, stars etc much like electrons in atomic and molecular orbitals. Additional matter particles then collect along these orbitals, forming rings or shells.

Contd:

Like the picture in this article, the rings of matter already existed in this galaxy, which were only illuminated by the eruption of intense radiation at the galactic core

The solar system and even the satellites around large galaxies (like the local group of the Milky Way) can be conceived of such quantized formations. The cases for supernova 1987A and a star are shown below:

@cd-Duck boy
using the exact same logic, we can see that it is far more likely that the above is really a dart board for the flying spaghetti monster, if you just look at this simple pic
http://thumbs.dre...4049.jpg

(without the darts, that is)

so, using your logic, we can then extrapolate that the entire region of space is soon to be invaded by dart shaped high speed projectiles seeking to hit the center (if possible)

OR
it's bullseye's head floating in free space and the first possible proof of a Boltzman brain!

or is it just colin farrel meditating?

any of which are just as credible as your post because it uses the exact same logic...

This is very interesting, as it could allow us to recreate the 3D structure of the emission pattern by backprojection...and maybe even a 4D movie of x-ray flares.
