Publisher description: Searching for signals from other worlds is a great venture of our time. If extraterrestrials are out there, we may be able to find their broadcasts--which would reveal fascinating New Worlds that are home to minds something like our own. Over one hundred searches for 'little green men' have been made over the last 50 years without finding ET. Most searches were modest--often a single professor working part-time, viewing a short list of stars for a few minutes each, and listening on a thin sliver of frequency smaller than one television channel. The sky could be blaring with radio super-stations at places on the radio dial that we've not yet tuned, or flickering with laser flashes that our few optical searches have yet to spot. It's possible that nobody is out there, or that they don't broadcast, or that they are too far away, or that our searches will be fruitless for other reasons. But it's worth searching because finding Others would change our view of things in a big way--and might even bring us goodies including better television programming.
