. 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.

In 1755, Immanuel Kant had the remarkable insight that stars and planetary systems form by the gravitational collapse and rotational flattening of interstellar clouds. Later in the 18th century, Marquis Pierre Simon de Laplace refined Kant s idea by suggesting that planets condensed from rings produced at the edge of a contracting disk while the Sun formed at the center a picture thereafter known as the Nebular Hypothesis. ...
