The ocean-filled moon might hold the life we’ve long searched for in space. And scientists have one shot to reach it.
Well, nobody is really sure. In fact, nobody is entirely certain that alien lifedoesexist alongside known life, but some scientists think that there is a scientific basis for believing that it does. Philosophy professorCarol Clelandfirst coined the term "shadow biosphere" in 2005, while heading...
