Website outage
Multiple disk failure resulted in a web site outage. We think we've recovered almost everything from the web site, so it should be back up and running.

RIP Jimmy Carter
Carter wrote the following on June 16, 1977 and placed it in Voyager 1, which is the most distant human-made object from Earth:

This Voyager spacecraft was constructed by the United States of America. We are a community of 240 million human being among the more than 4 billion who inhabit the planet Earth. We human beings are still divided into nation states, but these states are rapidly becoming a single global civilization.

We cast this message into the cosmos. It is likely to survive a billion years into our future, when our civilization is profoundly altered and the surface of the Earth may be vastly changed. Of the 200 billion stars in the Milky Way galaxy, some – perhaps many – may have inhabited planet and spacefaring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message:

“This is a present from a small distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours. We hope someday, having solved the problem we face, to join a community of galactic civilizations. This record represents our hope and our determination, and our good will in a vast and awesome universe.”

--- Jimmy Carter, President of the United States of America, the White House, June 16, 1977

Citizen Science SETI Project at UCLA.
Jean Luc Margot, a SETI Researcher at UCLA has started a Citizen Science project at UCLA. Participants will help identify and classify types of Radio Frequency Interference (RFI) seen in the data that they have taken at the Green Bank Telescope. This is an important step in identifying any signals that don't look like RFI.
