In our galaxy there are over 120 different globular clusters. Whats strange about them is that their stars are stable large stars and extremely older than the sun maybe 13.8 billion years old. I would expect if life needed time to inhabit a planet I would look here. The stars are closer together. Do we ever look amongst these old stars for radio emissions, If we do are they nearby? The large magelliac cloud and small magellic clouid are 2.

Basically S@H looks wherever the telescope(s) are pointing. As a project they don't buy 'scope time, but piggyback off other's.

The only time I can think of when S@H looked at specific locations was when they managed to get some observation time on the GBT when they looked at stars that are known to have planets from the Kepler studies.

Rob is correct, Seti@home can only get the data that they are supplied with. The dream in the future is for "Nitpicker" to determine what should be looked at again, and Seti given their own time on the telescopes to do that. However I suspect that money and politics will preclude it.

Might be worth a shot nearby stars arent turning up anything.

It would be nice if Seti had more telescopes to search more sky...

But they would still need to search and sift that extra data for meaningful signals that are worth investigating further i.e Nitpicker. Surely we have enough data stored away now to begin phase 2, rather that embarking straight away upon phase 3?

Like I posted over in the Mars exploration thread and after thinking about it some more old stars in globular clusters are probably not good candidates for providing anyone a satisfactory home as they are first or second generation stars and will not have produced the heavier elements needed to support life. Also I would try to find out what the spacing between stars is. Our solar system is in a region of the milky way where the density of stars is low enough to keep radiation levels below a fatal dose. Our star is at least a second or third generation star that formed out of a nebula created by earlier supernovas having created the necessary heavier elements.
