Explanation: Why would x-ray rings appear around a gamma-ray burst? The surprising answer has little to do with the explosion itself but rather with light reflected off areas of dust-laden gas in our own Milky Way Galaxy. GRB 221009A was a tremendous explosion -- a very bright gamma-ray burst (GRB) that occurred far across the universe with radiation just arriving in our Solar System last week. Since GRBs can also emit copious amounts of x-rays, a bright flash of x-rays arrived nearly simultaneously with the gamma-radiation. In this case, the X-rays also bounced off regions high in dust right here in our Milky Way Galaxy, creating the unusual reflections. The greater the angle between reflecting Milky Way dust and the GRB, the greater the radius of the X-ray rings, and, typically, the longer it takes for these light-echoes to arrive.

Sorry about the double post of the image. My mouse is doing that double click thing more and more. I am getting a replacement.

The violence of the events which produce these photons is literally beyond comprehension.

Remarkable how much that looks like Star Trek's The Doomsday Machine, as Captain Kirk piloted a doomed starship into the device's maw.

Still awaiting the Giant Meteors!!! The giant meteor of death is coming. I am starting an insurance company to cover those afraid of being smashed into subatomic particles.
