SETI@home is in hibernation.

We are no longer distributing tasks. The SETI@home message boards will continue to operate, and we'll continue working on the back-end data analysis. Maybe we'll even find ET!

Thanks to everyone for your support over the years. We encourage you to keep crunching for science.

What is SETI@home?

SETI@home is a scientific experiment, based at UC Berkeley, that uses Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data.
