It's been almost 50 years since scientists first came up with the idea of looking for radio signals from extraterrestrial civilizations - and although there have been a couple of curious blips, we haven't yet definitively heard E.T.'s cosmic call. Now the experts in the search for extraterrestrial intelligence, or SETI, are wondering whether we've been looking in the wrong places for the wrong kinds of signals.

So where should we look? Historically, the SETI Institute's target list has favored Earthlike planets where life as we know it might have taken root. But in "Confessions of an Alien Hunter," Shostak suggests that on the basis of what we're learning about artificial intelligence, the most likely aliens to send signals would actually be artificially intelligent machines.
If E.T. is a big shiny robot, the strategy of targeting Earthlike worlds orbiting sunlike stars may turn out to be "a very antiquated idea," Shostak acknowledged during a weekend interview. "A world on which the whole thing can rust might not be the best place for it," he said. A better place, from the machine's point of view, would be in orbit around a star hot enough to provide the prodigious power required for the big broadcast.
