Reports, Torino impact hazard scale, latest news, and image gallery.

A new scale that will quantify the risk of an asteroid or comet hitting the Earth has been adopted by the International Astronomical Union.

Home page and archives of forum discussing geological, historical, and potential near-earth-object (NEO) impacts, NEO research and risk assessment, and social policies and social change to ameliorate impact effects.

A large asteroid could miss the Earth by only 38,000 kilometres (very close in cosmic terms) in 2027, according to new astronomical observations. What's more it will remain dangerously close for about 600 years, and chaos theory means that it is impossible to predict its trajectory with enough accuracy for more than a few decades in advance.

Collected explanations, descriptions, articles, and links relating to historical and potential earth impacts by asteroids.

Assembled since 1985 by researchers at the Geological Survey of Canada (a division of Natural Resources Canada), this site also includes an article on impact cratering, a FAQ, and images.

An organization raising funds for projects that search for threatening asteroids.

Describes how a gigantic planet is approaching the Earth and the changes that this fact will bring about.

Describes the threat posed by a comet or asteroid impact and provides disaster preparedness planning for such an event.

There is a tremendous difference in the estimated dangers of asteroids, stretching on what separates legitimate science from pseudoscience. Ten recent trade books are reviewed that span a broad range in interpretations.

New research indicates that in the short term, the threat is more from smaller space objects.

Demonstrates how Nibiru can be found from ancient monument.

The prophecies of the Bible and Nostradamus predict that an asteroid or comet could hit earth.
