... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

. In an effort to provide a centralized database for indexing locations and descriptions of Shuttle debris, the editors of Astronomy Net have generated a database and web page where reports can be logged. This may or may not prove useful for cataloging debris reports, but Astronomy Net is happy to dedicate computer resources to help out any way possible. We express our sympathy and prayers to the families and friends of the Columbia crew. If you have located Shuttle debris, report it here.
