A sixteen year long astronomical study, led by Dr. Reinhard Genzel of the Max-Planck-Institute for Extraterrestrial Physics, has provided what is considered to be the best empirical evidence yet of the existence of

stellar orbits [QT] in the
Galactic Centre [QT] show that the central mass concentration of four million solar masses must be a black hole,
beyond any reasonable
doubt."

Breathtaking Hubble picture of the Sombrero Galaxy (also identified as M104). The Hubble Heritage team took the original images during May and June of this year using the Advanced Camera for Surveys and multiple color filters. They then stitched 6 images together to make the final composite image.

A computer aided simulation builds a spiral galaxy from
its beginning. In all, 390,000 particles were placed in an arrangement similar to a newborn galaxy. The end result after three months is an event that is believed to take billions of years to occur.
