"Where are all the aliens?" Goes where no book has gone before. In it you will not find any equations, but you will find scientific answers to questions such as "What is life?" "Where is life likely to be found in the Solar System?" "Are there planets suitable for life outside the Solar System?" "How do you find planets that are suitable for life outside the Solar System?" "What exoplanets have already been found?" and "Where does the Human Race go in the future?" We don't promise that after reading this book you will know everything about astrobiology, but, you will certainly be able to hold your own when the after dinner conversations turns to extraterrestrials.
