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.

"Is there anyone else out there???" Hopefully we will be able to find out some day. It would be a lonely place if 'we are all there...


Arecibo Status
I've been asked by several people to post a status update on the situation at Arecibo following hurricane Maria's passage.

Unfortunately, at this point we haven't gotten any news. The last information we have is from a couple hours prior to when the eye passed Arecibo. That report said all the employees were accounted for and in sheltered buildings.

Since then we've had no news. That's understandable. With power out on the whole island, electronics communications aren't going to be possible for some time. Heavy rains are still expected today, so I'm sure that the primary concern is still keeping everyone safe. Assessment of any damage will take time.

Let's hope that everyone is safe, that their homes are intact, and that any damage can be repaired quickly.

Data from "Tabby's Star" is flowing.
For those who didn't recognize the name KIC8462852 in their work unit names, this data comes from GBT observations of Tabby's Star (aka Boyajian's Star, aka WTF-0001, aka the Weirdest star in the galaxy). This is not yet the full data set, which lives at Penn State, it's some test on-target/off-target observations that we're checking out.

You might also notice another change. We've doubled the size of our work units which will reduce our quantization noise by 34%, and, depending on the strength of other noise sources, could give us as much as double that as a sensitivity increase.

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.
