Chandra's image of the Galactic Center (left) has provided evidence for a new and unexpected way for stars to form. A combination of infrared and X-ray observations indicates that a surplus of massive stars has formed from a large disk of gas around Sagittarius A*, the Milky Way's central black hole (illustration on right).
In the illustration at the right there is a monstrous black marble in the center of the galactic disk. Does that represent the actual relative size of the central black hole?
