Black hole may spin rapidly, slowly or not at all, study finds
The black hole in the Cygnus X-1 system could be spinning almost as fast as physically possible, or barely spinning at all. A team including scientists from the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences and the University of Lodz has shown that the answer depends on how the X-ray radiation from the system is modelled.

Venus appears pale yellow in visible light, but looks dramatically different in ultraviolet, where dark and light bands are visible across the planet’s clouds. Scientists have now developed a model that narrows down what the mysterious substance responsible for this strong ultraviolet absorption could be, according to the Institute for Basic Science (IBS) in South Korea.
