Barred Spiral Galaxy NGC 1300

There is a bar across the center of the spiral universe. There is a small spiral at the center of this bar. There is a black hole at the center of the spiral. One of the most detailed Hubble images is a view of the island universe. The Hubble image shows the central bar and spiral arms of the galaxy. Research on how the giant bar formed, how it remains, and how it affects star formation continues.

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.
