Life Beyond Earth
There has been, until now, no compelling evidence for biology beyond the confines of our own planet. And yet, people who investigate this topic feel confident that – within two decades – we will trip across life forms that are not, and never have been, earthlings. Why are they so optimistic that we will soon find some cosmic confrères, and what might be the implications of such a discovery?
