Another brick down the wall. An unusual and still unexplained radio signal detected by NASA's Kepler satellite baffled scientists. The 2012 hunt is starts!

The search for extraterrestrial life just got a little closer to its goal. Scientists released preliminary results Friday of signals from NASA's Kepler satellite as part of the Search of Extraterrestrial Intelligence based out of the University of California Berkeley.

This radio signal doesn't show intergalactic life yet, but has researchers hoping that signals like it in the future from NASA's Kepler mission may uncover life beyond Earth.

From the SETI project group:

"We know these signals are interference, but look similar to what we think might be produced from an extraterrestrial technology. They are narrow in frequency, much narrower than would be produced by any known astrophysical phenomena, and they drift in frequency with time, as we would expect because of the doppler effect imposed by the relative motion of the transmitter and the receiving radio telescope. Even though these signals are interference, detecting events with similar characteristics to what we expect from ET is a good indication that the first steps of our detection algorithms are working properly."

However, two signals, KOI 817 and KOI 812, seem to come from a single origin and are affected by the Doppler effect, similar to the sound of a passing ambulance. That means the signal could be moving away or towards the Earth, not coming from an Earthling source itself.


Researchers said they expect new data to be released in the upcoming weeks from the nearly 50 terrabyte data trove collected in early 2011.

We wait.

I'm not sure that's from the SETI project group, as I can't find it on their website, rather their website contains this apparently contradictory information:

Update: Friday, January 6, 2012 After posting the plots below on January 5, it became clear that we had not stated as definitively and absolutely as possible that these signals are interference. We have updated the post to make this clear. Sorry for any confusion.
That's dated Jan 6, the article you cited is dated Jan 9, so it appears to be a HOAX! or something.

Also there's already an existing thread which points out that Jan 6 clarification:
SETI finds alien signals?

Being in radio myself, I have to agree.
The distances are too great and radio signals are far too weak.
Stars put out orders of magnitude higher power radio waves than communication radios do.
So to receive ET's general radio traffic one of their dishes would have to be:
1.Accidentally aimed in our direction.
2.Putting out incredible amounts of power.
3.Not be anywhere next to a star. (from our point of view)
4.Be transmitting at the same time we have our dishes pointed at them. Just how often does NASA transmit to our deep space probes?
