Aliens and Other Worlds /anglais Book

Did life on Earth arrive on a meteorite from outer space? Are there living beings on planets beyond our solar system? If they are out there, what might these aliens look like? Would they be smart, curious, scared? Would they even want to meet us?
Revealing the wonders of scientific inquiry, astrophysicist and best-selling author Lisa Harvey-Smith guides Earthlings young and old through our search for alien life. On the way, she considers where our best chances are to find any galactic neighbours; ponders whether they might already be living among us; and looks at what we might learn about aliens from life at Earth's extremes.
Asking all the important questions, answering some and explaining why others need further investigation, Aliens and Other Worlds explores the mystery of life beyond Earth. With illustrations by acclaimed artist Tracie Grimwood, this awe-inspiring journey will thrill anyone with eyes fixed on distant horizons.
