In this picture, our planet is represented as a tiny blue dot, lost in the vast expanses of space.

It will attract those interested in astronomy, exoplanets, the search for extraterrestrial life and the future of mankind. Sagan writes in accessible language, which makes his ideas understandable even to those who do not have deep knowledge in the field of science.

Clarke will find much in common in The Blue Spot a book about dreams, exploration, and how we can become part of something bigger. The topics raised in the book cover not only scientific aspects, but also philosophical questions about our place in the world.
