First Alien Signals Found By SETI

Why are these signals interesting?

These signals 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"

We've started searching our Kepler SETI observations and our analyses have generated a few 'hits,' but all are undoubtedly examples of terrestrial radio frequency interference (RFI). Each of the signals below is shown in a pair of plots, one from an observation of Kepler Object of Interest (KOI) 817 and one from an observation of KOI-812. During an observation, we alternated between targets to enable us to rule out signals seen coming from two different places in the sky. If we see a signal coming from multiple positions on the sky, like the ones below, it is very likely to be interference.

What do these plots represent?

These are plots of electromagnetic energy as a function of frequency and time. Brighter colors represent more radio energy at a particular time and frequency. For example, a radio station transmitting at 101.5 MHz would produce a large amount of energy near that frequency.

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.

What's next?

These first results are tests of the algorithms we'll apply to all our observations of Kepler planets. During the coming weeks, we'll be posting more of our results as we process the nearly 50 TB of data we collected in early 2011

I doubt we would ever get official confirmation of this
I would say they probably found others but it is a need to know basis, locked away in some government vault

Fascinating post Sav! :flop:

I ran the SETI@home processor for a long long time, I hope they nail it!

Reading it now, nice post, its confirmed natural interference yes ? It is interesting that they have refined the tech

Nice post man

Are We Still Alone? Scientists Analyze First Kepler Scans

The Search for Extraterrestrial Intelligence (SETI) project, which has begun its first analyses of the scans of 86 exoplanets uncovered by the Kepler Space Telescope, has found the first batch of hits within the data stream, according to scientists at University of California, Berkeley.

“We’ve started searching our Kepler SETI observations and our analyses have generated some of our first candidate signals,” the UC Berkeley scientists announced on Friday.

However, the team said additional analyses have shown that the signals are just old fashioned terrestrial radio frequency interference. But they are saying that is not necessarily a bad thing.

Although the interference comes from a source here on Earth, the detection of any artificial signal provides the team with a great opportunity to understand the kind of artificial (alien) signals they hope to eventually discover.

“These signals 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,” said a statement on UC Berkeley’s website (http://seti.berkeley.edu/kepler-seti-interference).

The Berkeley scientists are processing the data taken from Kepler since early 2011. They have picked up some interesting signals from candidates — referred to as Kepler Object of Interest (KOI). Although none so far seem to be anything more than terrestrial interference. If a single signal comes from multiple positions in the sky, as these ones do, it is most likely to be interference.

In this case, the narrow, shifting frequency of the signal matched the characteristics that researchers were expecting to see in an artificial radio signal from space. However, these characteristics also matched radio signals created from our own satellites around Earth.

The scientists tested the radio signals to determine where they originated by moving the telescope to scan other regions of space. After all, if a radio signal is being generated by a source in space, then pointing the telescope elsewhere would eliminate the detection of the signal. Since when doing so, the signal persisted, the team came to the conclusion that the signal was in fact coming from our own satellites.

The SETI project plans to continue to analyze the nearly 50 terabytes of data generated from its Kepler observations, and the group will update its blog with any additional results that pop up throughout the next many months.

The Kepler Space Telescope is currently looking for other exoplanets orbiting stars in the heavens. It does this by constantly looking at the same patch of sky, waiting for the distant worlds to pass in front of their parent stars. When one does pass in front of its parent — called a “transit“ — the starlight dims slightly, and Kepler registers it as a “candidate” exoplanet. Four transits must be completed before the world is confirmed.

One of the prime directives for the Kepler mission is to find Earth-sized exoplanets orbiting within the habitable zone of sun-like stars. The team said it would take 3.5 years for Kepler to confirm such an existence.

Looking for signals in the cosmos is like looking for a needle in the haystack; until now we were searching blind, starting even before we knew if there were any other planets out there or not. We now know there are billions of planets in our galaxy alone, based on Kepler data. And it is believed a majority of those planets are probably small, rocky worlds similar to Earth and Mars.

Determining how many of them are actually habitable may be impossible, but finding them will help narrow down the search, providing probable actual targets to turn the radio telescopes toward instead of just trying to search billions of stars overall.

Look how many people viewed your crappy thread!!! :rtft:

...750 or so by this time. Way to get everyone's hopes up for nothing.

Forgive me, I know about those creepy aliens. I've gotten use to it. I don't even care about extra-terrestrial disclosure anymore because, if you knew what I knew, you'd know that our puppeteers are in the dark about it and the whole worlds brilliant minds can't help them figure it out because they're utterly disgusted with how we're conditioning our youths to kill and rip each other off.

If you want to make a difference, just pay it forward dude (or dudette possibly?) TIA.

Hey sav, how old is this article? I was watching a video from some lady who works at SETI, was saying that one of the signals that they have detected and thought was E.T in nature was actually from a satellite that we have orbiting our Sun, any relation?

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.
