This article exhibits the pleasing characteristic of - at least - not displaying atrocious errors of scientific fact, as do far too many popular articles written about ongoing research.

Incidentally, one poster wrote above that the author of the article states without qualification with respect to the presumed black hole 'Sagittarius A' that its "Schwarzschild radius around the supermassive black hole extends about the same distance as the orbit of Mercury." This is an established fact, described in, among other publications, Schodel, R., et al., Nature 419, 694 (2002) and Ghez, A. M., et al., ApJ 586, L127 (2003).
