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.

Help us improve RFI removal and scoring
The SETI@home back end is getting closer to completion.

  • Our algorithms for removing RFI and finding repeated signals work fairly well.
  • We can inject "birdies" (synthetic signals) to measure how well they're working.
  • We've developed tools for browsing, drilling down, and visualizing signals and candidates.

At this point we need to manually scan lots of results, looking for cases where our algorithms don't seem to be working perfectly. If you like, you can help us with this.

Jodrell Bank to partner with Breakthrough Initiatives
At Berkeley SETI Research Center, we've long been friends and collaborators with Professor Michael Garrett and the team at Jodrell Bank. We're delighted to continue our collaboration as the Breakthrough Initiatives announce a formal partnership with Jodrell in the search for intelligent life beyond Earth: https://breakthroughinitiatives.org/News/11

Although this partnership doesn't involve data from telescopes at Jodrell flowing to SETI@home (at least at the present time), the sharing of data, algorithms, and strategies will benefit the science programs at Berkeley and Jodrell, as well as at other telescopes involved in Breakthrough Listen and in SETI in general. You can seen an interview with Mike, recorded a few weeks back, at https://youtu.be/ZRMiuCFACCw, and take a 3D tour of the Lovell telescope and control room at Jodrell at https://my.matterport.com/show/?m=B8UZb1joxsG.
