All These Worlds Are Yours: Scientific Searches for Extraterrestrial Life

Where and how to search for aliens? The idea of extraterrestrial life has fascinated humanity long before the beginning of space exploration. John Willis, an astronomer and science popularizer, presents five of the most realistic scenarios for searching for alien life in our Galaxy. Describing the latest achievements in space exploration - the results of the Kepler space telescope, the study of Mars using the Curiosity rover, the flyby of Pluto by the New Horizons probe, and many others - Willis gives readers the opportunity to choose their own method of discovering extraterrestrial life. He invites us to ponder its existence under Martian ice, on Jupiter's moon Europa, and on Saturn's moons Enceladus and Titan, while the current conditions on Titan are viewed through the lens of the distant past of our own planet. Willis also looks beyond the Solar System, discussing the chances of finding a "second Earth" among the billions of exoplanets likely existing in our Galaxy, and listens to the distant cosmos in hopes of hearing alien radio signals.
