Are We Alone?:

For decades a heroic band of astronomers has been sweeping the skies with radio telescopes in the (tiny!) hope of stumbling across a message from an alien civilization - a project known as SETI (the Search for Extraterrestrial Intelligence). What is the basis for the belief in intelligent aliens? And what would happen if SETI succeeded? How would it affect our science, our religions and our world view? This little volume looks at the history of belief in alien beings and charts the progress of modern SETI.
