Description
Ever since the concept of other worlds was put forward in the fifth century BC, scientists have struggled to answer that eternal question: Are we alone?
Asimov here covers many fascinating aspects in his analysis of the universe - interstellar flight, the origin of life, messages to outer space, space exploration, the solar system - and gradually reaches his conclusion that are as convincing as they are fantastic.
