Searching For Aliens

SETI researchers have already begun focusing their search for alien radio signals on Earth-like exoplanets found by the Kepler planet-hunting spacecraft. That list will almost certainly grow as Kepler continues its mission. There is also another possibility. Astronomers have found Jupiter- and Neptune-type worlds orbiting in the habitable zones of their stars, and speculate those exoplanets could have Earth-like exomoons. If such giant satellites are discovered, they would also be SETI possibilities.

This, of course, constitutes a new era for SETI. Heretofore, researchers would sometimes target Sun-like stars, but most SETI searches scanned the sky.
