SETI find interesting signals from Kepler planets, but it’s NOT aliens.

January 10, 2012

So there has been some excitement and confusion lately over a signal discovered by SETI researchers after they aimed one of their radio telescopes toward “objects of interest” discovered by the Kepler mission. These are possible exoplanet discoveries, but they’ve yet to be confirmed by other telescopes. (These are called Kepler Objects of Interest, or KOIs.) Until now, SETI researchers have been blindly aiming their telescopes all over they sky listening for possible alien radio signals. Now that the Kepler team has a few KOIs that might be habitable, it makes sense for SETI to narrow their search and start listening specifically in the direction of those KOIs. Well, they did just that, and they found an interesting signal! One that is clearly not just natural background noise. But, that signal is almost definitely interference from one of our own satellites, because the signal still shows up even when they aim the radio telescopes away from the exoplanets. So, don’t let anyone fool you- SETI has NOT discovered an alien radio signal.

As he always does, Dr. Phil Plait of Bad Astronomy lays out the truth on this. Universe Today has an excellent post on it as well.
