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.

News

Bryon Leigh Hatch and Arecibo have passed on.
We got two pieces of really bad news yesterday. Byron Leigh Hatch, founder of the Carl Sagan team, all around smart and thoughtful guy, and a setizen since shortly after SETI@home began in 1999, passed away in August. There is a thread for leaving remembrances here. He will be missed.

And, of course, we were informed of the collapse of the elevated structure at Arecibo. It was clear after the second cable broke, the structure would come down soon. As much as we were unhappy that the repair efforts had to be abandoned because of the danger, it's clear now that it was the right call. It's our hope that we will find national support for building new scientific facilities on Puerto Rico in the near future.
