A Place Like Home,ources told us more about ourselves than about alien beings, but the tracks were being laid for more sophisticated communication attempts. We now know something about the distant Earths out there, and we are developing techniques to find out what they are like and even whether they host living biomes and beings

Theoretical Frameworks for Washback Studies,any may harbor Earth-like conditions, even some gas giants orbit within habitable zones. And though these behemoth planets themselves may not be inhabited, they may host many moons, some the size of planets, and these may constitute Earthlike worlds.
