X-rays in Space

A University of Leicester press release on the 8th of September (see www2.le.ac.uk/ebulletin/news/press-release/2010-2019/2010/09/nparticle.2010 ) claims that the source of powerful X-rays in a nearby galaxy are said to be proof of the existence of a new species of black holes – targeted because of its extreme luminosity (and advertising a paper in the Astrophysical Journal published the same day).
