SETI@home is a screen saver that lets you and hundreds of other Internet-connected computer users detect signs of intelligent life elsewhere in the universe.
SETI@home is a scientific experiment that harnesses the power of hundreds of thousands of Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running SETI@home which 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 consists of two parts: an "application" and a "screensaver". The application downloads blocks of data from the Internet, performs the number crunching on that data (looking for orderly patterns that might be artificial), returns the results, and gets another block of data. The application is represented by a green radio telescope icon in the System Tray.
The screensaver runs when you haven't used your keyboard or mouse for a while. It displays color pictures showing the data analysis process. Normally the application processes data only when the screensaver is running. Optionally, you can have the application process data all the time.
This newest version offers improved security, support for SOCKS proxies, better HTTP proxy support, improved network connection retries, and improved Gaussian curve graphing.
