Are aliens talking to us?

SETI@Home News - Fri, 2016-10-14 17:51
WIRED interviewed Berkeley SETI Research Center's Steve Croft and Eric Korpela, and the SETI Institute's Seth Shostak, about one method we use to figure out whether claimed ETI signals are legit:

Another probable non-detection of ET

SETI@Home News - Tue, 2016-10-11 23:46
Dr. Korpela has posted his thoughts about the claimed detection of pulsed emission from extraterrestrial intelligence being beam at Earth from 234 different stars. He's not optimistic.

The Breakthrough Listen project has also posted a statement of a similarly cautious tone.

Replica database offline...

SETI@Home News - Sun, 2016-10-09 20:18
The replica database will be offline until we can restore it from the primary database on tuesday (at the earlies). This will result in slowness of the web site and the scheduler.

Weekly outage

SETI@Home News - Thu, 2016-09-01 04:28
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.

"Baffling" "signal" "from HD 164595" is probably none of the above.

SETI@Home News - Mon, 2016-08-29 17:50
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.
