Are we alone? Alien Signal Search explores the compelling quest to detect extraterrestrial intelligence. The book investigates the multi-faceted Search for Extraterrestrial Intelligence (SETI), detailing the technological hurdles of identifying faint signals across interstellar distances. It also examines the scientific methods used to differentiate artificial signals from naturally occurring phenomena, and contemplates the profound philosophical implications of contact with an alien civilization.

The book begins by tracing SETI's history, from its humble origins to today's sophisticated projects, including the Allen Telescope Array and SETI@home. It then delves into signal detection principles, ongoing SETI projects, and the complexities of signal interpretation.

The book emphasizes that while finding extraterrestrial life is a long shot, the potential rewards make it a worthwhile endeavor. It distinguishes itself by presenting a balanced, accessible overview of SETI, appealing to science enthusiasts and anyone curious about the possibility of life beyond Earth.
