SETI@home -- SETI@home is a scientific experiment that will harness the power of hundreds of thousands of Internet-connected computers in the Search for Extra-Terrestrial Intelligence (SETI). You can participate by running a program that downloads and analyzes radio telescope data. There's a small but captivating possibility that your computer will detect the faint murmur of a civilization beyond Earth. SETI@home is scheduled to start in April 1999. The SETI@home program is a special kind of screensaver. Like other screensavers it starts up when you leave your computer unattended, and it shuts down as soon as you return to work. What it does in the interim is unique. While you are getting coffee, or having lunch or sleeping, your computer will be helping the Search for Extraterrestrial Intelligence by analyzing data specially captured by the world's largest radio telescope. You will be able to download the SETI@home program for free.

Anticryptography "Anticryptography is based on the idea of making a message that decodes itself. The idea is closely linked with the search for extraterrestrial intelligence and is an attempt to answer the challenge of communicating with another, perhaps vastly different, intelligence"
Arctic Asteroid! residents of Western Canada were surprised when a fireball as bright as the Sun streaked across the morning sky. Exploding with an estimated yield of 5-10 thousand tons of TNT, the brilliant meteor attracted the attention of defense satellites, seismic monitoring stations, and just about anyone who happened to be standing outdoors within 700-800 km of the dazzling meteor's path

At L1, it unfolded its collectors and began a two-year "sunbath." Upon its return to Earth in 2004, scientists will study the solar wind samples for years to come"
