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.

Mail problems and fire near SSL.
The UC Berkeley Space Science Laboratory Domain Name Services (DNS) server has been having problems for the past 24 hours, and a wildlands fire near the Space Sciences Lab has prevented SSL personnel from fixing the problem.

Because of this, any server functions (i.e. password reset, forum notifications) that require email interaction are not working for most people.

If the problems continue tomorrow its likely that BOINC clients will eventually lose access to the SETI@home servers until the DNS server can be repaired.

Interview with Green Bank scientist Ryan Lynch
Ryan Lynch works on pulsar research at the Green Bank Observatory. In this video, we sat down with Ryan to chat about how to paint the world's largest steerable radio telescope, and what modern convenience he misses most while living in the middle of the National Radio Quiet Zone.

A 3D tour of the Green Bank Telescope.
We took a GoPro Omni 360 VR camera up to the top of the Green Bank Telescope, the largest steerable radio telescope in the world. Join us on Part 1 of our journey, as we check out the telescope wheels that each carry more than a million pounds of weight, and learn about the 2004 individually controllable panels that make up the surface of the dish, which is larger than a football stadium.

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.
