Galactic Center Research

In Natures 17 Oct 2002 issue (get article) we report on having observed 2/3 of a complete orbit of the star currently closest to the enigmatic radio source Sagittarius A*, which is thought to mark the location of our Milky Ways massive central black hole. As explained below, this orbit provides overwhelming evidence that SgrA* is indeed a supermassive black hole of more than 2 million solar masses. Figures 1,2, and 4 on this page are taken from the article in Nature. See the star S2 swing around the black hole in this movie.
