Presentation
Spectacular technological advances, developed in recent years by the scientific community, now make it possible to discover an ever-increasing quantity of new celestial bodies.
In their number, exoplanets are a prime target for detecting clues of circumstances favorable to the emergence of biological activity.
As our planet is the only known star that has met these demanding conditions, astronomers hope to identify twin planets of ours, "exo-terrestrials", and, among them, to find the rare pearl in which life appeared.
In addition to the usual data useful for observations, find in this astronomical diary all the methods used to explore these distant planetary systems, the space missions and scientific programs dedicated to them, the emblematic figures and major events that have contributed to the advancement of knowledge in this vast field, source of dreams and bearer of hope.
A planisphere is included in this book.
