This book explores the questions of What, Why, When, How and Where might we might find extra-Terrestrials (a.k.a. Aliens) and their habitats throughout the Universe– and Who might they be?

Starting from ourselves and the Earth and eventually speculating about life forms that might span multiple Universes, it provides an accessible introduction to extra-terrestrial life, the search for extra-terrestrial intelligence, and exoplanets. It will enable readers to appreciate, follow and sometimes answer questions on life and planets outside Earth. It details these exciting topics by pondering what comprises an alien life form and what suitable habitats might exist for them inside and out of our solar system. The book also looks ahead to the future and the realities of finding alien life and the possibilities of

mankind leaving Earth and living on another planet.

This guide is accessible to those without a formal scientific or mathematical background. It will also be of interest to students of astrobiology, astronomy, astrophysics, planets throughout the Universe, the origin and evolution of life-forms beyond the Earth and (perhaps) of the ultimate limits attainable by life in the Universe, who are looking to learn more about those of the same topics which are outside their own specialisms.
