Аннотация

“Are we alone in the universe?” is one of the oldest and most universal questions. For a century or more it has stimulated brilliant science fiction—and it’s now incentivizing real science and exploration. But we still lack evidence—indeed we know too little to say whether intelligent aliens are likely or unlikely to exist. That’s why we need all the arguments that can be mustered. And that’s why this book will be such a stimulus to all enquiring minds.
There may be simple organisms on Mars, or remnants of creatures that lived early in the planet’s history; and there could be life, too, in the ice- covered oceans of Jupiter’s moon Europa, or Saturn’s moon Enceladus. But few would bet on this; and certainly nobody expects a complex biosphere in such locations. For that, we must look to the distant stars—far beyond the range of any probe we can now construct.
