NASAs mission to probe the Van Allen belts has found a third ring of high energy 12,000 miles above the surface of the Earth.

At www.sciencedaily.com/releases/2013/02/130227132544.htm … we learn that NASAs NuSTAR X-Ray space observatory, in association with ESAs XMM-Newton satellite has found a black hole that is said to spin as fast as Einstein's theory of gravity will allow. Published by Nature, Feb 28th 2013, the study and observations are said to support the theory of general relativity which says gravity can bend space-time (see also www.nasa.gov/nustar and http://phys.org/print281190007.html and dx.doi.org/10.1038/nature11938)
