What is SETI@home?
SETI@home is a scientific experiment 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.
Get started
, install and run the BOINC software used by SETI@home. When prompted, select SETI@home from the list of projects.
Have questions or need help? Contact a volunteer using .
Special instructions:
Keep your computer busy when SETI@home has no work - .

Me llamo Marcos vivo en Pontevedra(Galicia). Siempre me ha gustado la astronomía ya que me parece algo realmente interesante y de lo que desconocemos...
Weekly Outage and Initial Catch Up
Every Tuesday morning () we begin a four hour data distribution outage for database and systems maintenance. The upload/download servers will be offline during this time. Afterwards you may experience connectivity issues for several more hours as the servers catch up with demand.
Behind the scenes at Berkeley SETI: Part II
In our latest video, Berkeley SETI Research Center Engineer Dave MacMahon takes us into the server room and shows us some of the equipment that powers the search:

Weekly outage
Sorry about the misinformation on the weekly outage.
When we're in outage mode the message uses the current day of the week as the day of the weekly outage.
We will go back to Tuesday outage next week.
The delay in the outage this week was due to the media flap over the Russian announcement.
Breakthrough Listen observations of HD 164595
The Breakthrough Listen team has
their archival search for emission from HD 164595 and the initial analysis of their recent observations of that target.
"Baffling" "signal" "from HD 164595" is probably none of the above.
I'm sure that many of you have seen the news reports of a "SETI signal" detected from the star HD 164595
I was one of the many people who received the the email with the subject "Candidate SETI SIGNAL DETECTED by Russians from star HD 164595 by virtue of RATAN-600 radio telescope."
Since the email did come from known SETI researchers, I looked over the presentation.
I was unimpressed.
In one out of 39 scans that passed over star showed a signal at about 4.5 times the mean noise power with a profile somewhat like the beam profile.
Of course SETI@home has seen millions of potential signals with similar characteristics, but it takes more than that to make a good candidate.
Multiple detections are a minimum criterion.
Because the receivers used were making broad band measurements, there's really nothing about this "signal" that would distinguish it from a natural radio transient (stellar flare, active galactic nucleus, microlensing of a background source, etc.)
There's also nothing that could distinguish it from a satellite passing through the telescope field of view.
All in all, it's relatively uninteresting from a SETI standpoint.
But, of course, it's been announced to the media.
Reporters won't have the background to know it's not interesting.
Because the media has it, and since this business runs on media, everyone will look at it.
ATA is looking at it.
I assume Breakthrough will look at it.
Someone will look at it with Arecibo, and we'll be along for the ride.
And I'll check the SETI@home database around that position.
And we'll all find nothing.
It's not our first time at this rodeo, so we know how it works.
