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.

Weekly Outage and Initial Catch Up
Every Tuesday morning (Pacific time) we begin a ten 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.

Projects are (no longer) down
Our upload server is malfunctioning. The projects are down until we can fix this.

Now accepting donations of gridcoin.
Because of several requests, I've resurrected the idea that we could take donation in gridcoin, a cryptocurrency you can earn by participating in volunteer computing projects.

Our gridcoin address is now listed on our donation page.

Special Fundraiser for Parkes Data Store and GPU development system
Thanks to our collaboration with Breakthrough Listen and their international colleagues, we will soon have the ability to access data recorded at the Parkes Radio Telescope in Australia. For the first time, this will give us full-sky coverage, including the southern hemisphere, in our search for ET. However, due to the enormous amount of data that the 13-beam receiver at Parkes can generate, we will require extra hardware to store and distribute it. We need your help to purchase this.

Thanks to some special offers, one from the Hanson family in memory of Robert W. & Mary P. Hanson, one from Richard Haselgrove in memory of his mother, Jenifer Leech, and one from Mr. Kevvy, we have the possibility to match donations which will allow us to purchase the Parkes Data store server (~$34K) and the GPU development systems (~$10K) we will need for the coming year. For every dollar you donate in this special fund raiser, Mr. Kevvy will match it, the Hanson Family will match it with two, and Richard Haselgrove will match it with two more. That means for every dollar you donate we'll get six dollars towards the purchase of these servers!

Because this is a special fundraiser we'll have special notation on your account page and on the forums. The 12TB disk drives in the Parkes Data Store cost $450. One sixth of that is $75. So, a donation of $75 or more gets you a disk drive icon. The GPUs in the GPU development machine that we will be using for our recording systems at future telescopes are $1500 each, so a donation of $250 or more will get you a GPU icon. And as always, any donation of $10 or more will get you a green star.

But in the end, it's not about the icons: it's about getting the data and making a discovery for the ages. Your help, whether by crunching data or by donating, is always appreciated.

Splitters off, again :(
I had to turn the splitters off, again. I underestimated the rate at which we were creating work (damn moveable decimal points!). I thought we could go without adding more space to the database until we had time (tomorrow morning) to delete the old database spaces.

I was wrong, we really zoomed through the files on disk, and we ran out of space. Deleting database spaces is dangerous, so I really want Jeff to check the command script before it gets run. That won't happen until morning. But once it does we'll be back in operation.

Hopefully most SETIzens won't even notice this short absence of work.

Berkeley SETI Research Center undergraduate research internships, summer 2018
Applications are invited for 10-week paid undergraduate research internships at Berkeley SETI Research Center for summer 2018. BSRC is a
world-leader in the search for extraterrestrial intelligence – the quest for a scientific answer to one of humanity’s oldest questions: Are we
alone in the Universe? Housed in the Astronomy Department at the University of California, Berkeley, the team at BSRC leads the science
program for the $100-million Breakthrough Listen project. Our scientists and engineers are pioneers in the development of software,
instrumentation, and science strategy for the search for intelligent life on other worlds. We have access to substantial amounts of time on
the planet’s largest telescopes, connections to leading players in industry, and we’re based in one of the world’s premiere astronomy
research institutions. We’re also psyched that we get to wake up each day and hunt for aliens.

Current sophomore, junior, and senior undergraduates (including non-US citizens) studying at a degree-granting institution in the US are eligible to
apply. Around 5 - 7 positions will be available. A stipend of $20 / hr (up to a maximum of $8000) will be provided. Details and links to the application form are at https://seti.berkeley.edu/Internship.html
