S+F this is brilliant news because I thought America had finished listening for alien signals when they pulled the plug on SETI in puerto Rico.

HEY! that's avatar is from one of my favorite games...wow I haven't even thought about that game or that lovable character in a while. What was his name again?

Green Bank Telescope observations to start Saturday. Grad student Andrew Siemion reports that new modifications to a data recorder at Green Bank that we need for our Kepler SETI observations are now complete, thanks to a huge amount of help from Paul Demorest, a former grad student and one of initial authors of AstroPulse. Our first hour of test time is scheduled for this Saturday, 17:30 EDT. We'll be observing with 450 seconds per target on 90 Kepler field stars with interesting planet candidates (~habitable zone, ~Earth size, ~Earth period, ~several planets), then do a raster scan of the entire Kepler field. 6 May 2011 | 22:29:54 UTC · Comment
May 14, 2011 - Washington Astronomers at the University of California, Berkeley are aiming a radio telescope to detect signals of alien life on 86 possible Earth-like planets.
The search began on Saturday, May 8, when the Robert C. Byrd Green Bank Telescope - the largest steerable radio telescope in the world - dedicated an hour to eight stars with possible planets.
The colossal dish will gather 24 hours of data on each of the planets, which have been selected from a list of 1,235 planets identified by NASA's Kepler space telescope "It's not absolutely certain that all of these stars have habitable planetary systems, but they're very good places to look for ET," saidC Berkeley graduate student Andrew Siemion.
The Green Bank telescope will stare for about five minutes at stars in the Kepler survey that have a candidate planet in the star's habitable zone-that is, the planet has a surface temperature at which liquidater could be maintained.
"We've picked out the planets with nice temperatures-between zero and 100 degrees Celsius-because they are a lot more likely to harbor life," said physicist Dan Werthimer.
After the Green Bank telescope has targeted each star, it will scan the entire Kepler field for signals from planets other than the 86argets.
The complete analysis for intelligent signals could take a year, Werthimer said. "If you extrapolate from the Kepler data, there could be 50 billion planets in the galaxy," he said. "It's really exciting to be able to look at this first batch of Earth-like planets," he added.
I'm a little confused as to thinking about time with alien planets. If we stand outside and look at a Star we are really looking at it's past because that is the light traveling towards us. But in actuality that star is older than our star. So would we detecting their current technology, or their past technology?
Does SETI search for natural Radio emissions from exo-planets? Or are they actually trying to detect technology?
We detected the exo-planets by observing the planets passing in front of the star. Would it be possible to build a telescope to detect if aliens built satellites in their solar system? Using the same method of planet hunting? I know we are talking about a huge increase, but I thought I've read/heard before if we had the funding we could build a telescope that large.
If we do detect life, is the next step to communicate with them in somewhat of real time? Say a 15 minute delay?
The exo-planet data that we have, is that information from the past? Isn't that done by signals bouncing back too?
Would detecting alien signals automatically imply those aliens have evolved to interstellar travel by the time that first signal reached us? If those aliens never went extinct? Say they're at the stage of building their first radio, and by the time that signal reaches our telescopes on Earth, 5000 years have passed on that alien planet.
I don't really know how it works, I think finding extremophiles is much more exciting, but detecting advanced alien life would be pretty creepy.
