OUR black hole. Part II
It seems that every galaxy harbors a black hole in its core. The larger the central bulge of older stars, the bigger the hole. Our Milky Way is no exception, but only recently have we developed techniques suitable for peering into the cocoon and measuring the massive, quiet beast lurking inside.

Black holes ain't that black then?
That black holes are a pain in the neck for astrophysicists is more or less well known. Infinites and zeroes are fine for mathematics but not to be found in Nature, yet a black hole in principle hides an infinite at its center, or that was accepted until now.
