SETI@home (“SETI at home”) is an Internet-based public volunteer computing project employing the BOINC software platform created by the Berkeley SETI Research Center and is hosted by the Space Sciences Laboratory, at the University of California, Berkeley. Its purpose is to analyze radio signals, searching for signs of extraterrestrial intelligence, and as such is one of many activities undertaken as part of the worldwide SETI effort.
SETI@home was released to the public on May 17, 1999, making it the third large-scale use of distributed computing over the Internet for research purposes, after Great Internet Mersenne Prime Search (GIMPS) was launched in 1996 and distributed.net in 1997. Along with MilkyWay@home and Einstein@home, it is the third major computing project of this type that has the investigation of phenomena in interstellar space as its primary purpose.
In March 2020, the project stopped sending out new work to SETI@home users, bringing the crowdsourced computing aspect of the project to an indefinite hiatus. At the time, the team intended to shift focus onto the analysis and interpretation of the 20 years’ worth of accumulated data. However, the team left open the possibility of eventually resuming volunteer computing using data from other radio telescopes, such as MeerKAT and FAST
The two original goals of SETI@home were:
- to do useful scientific work by supporting an observational analysis to detect intelligent life outside Earth
- to prove the viability and practicality of the “volunteer computing” concept
The second of these goals is considered to have succeeded completely. The current BOINC environment, a development of the original SETI@home, is providing support for many computationally intensive projects in a wide range of disciplines.
The first of these goals has to date yielded no conclusive results: no evidence for ETI signals has been shown via SETI@home. However, the ongoing continuation is predicated on the assumption that the observational analysis is not “ill-posed.” The remainder of this article deals specifically with the original SETI@home observations/analysis. The vast majority of the sky (over 98%) has yet to be surveyed, and each point in the sky must be surveyed many times to exclude even a subset of possibilities.

Rhyme by Anne Guitar
Dedicated to SETI@Home
I looked for aliens around me
Looked right, looked left – but none to see
Were they hiding? Were they here?
I listened closely but could not hear
I Googled them but only found
Sci-fi movies made on ground
So I joined SETI and now feel
I’m finally doing something real
Helping find intelligence
Alien ladies, alien gents
So one day I’ll find at my door
