Do you wonder if humans are the only beings who wonder if they are alone in the universe? Our sun is a star. In the night sky are all kinds of stars, and orbiting those stars are planets like the ones in our own solar system. Could those planets have life like we do on Earth? Planet Earth is not too big, not too small, not too hot, and not too cold. It’s just right. Our very own Goldilocks planet . . . . Follow a young girl as she explores these questions in this gorgeous book about the wondrous search for another Goldilocks planet.

Where would you look for alien life? An astronomer and science popularizer explains the basics of astrobiology to outline five plausible scenarios for finding extraterrestrials Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy. Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks readers to imagine--and choose among--five scenarios for finding life. He encourages us to wonder whether life might exist within Mars's subsoil ice. He reveals the vital possibilities on the water-ice moons Europa and Enceladus. He views Saturn's moon Titan through the lens of our own planet's ancient past. And, he even looks beyond our solar system, investigating the top candidates for a "second Earth" in a myriad of exoplanets and imagining the case of a radio signal arriving from deep space. Covering the most up-to-date research, this accessibly written book provides readers with the basic knowledge necessary to decide where they would look for alien life.

A poetic exploration of our solar system and all the wonders that lie beyond

The search for life in other worlds begins with the search for a habitable planet. This book explores the “Goldilocks Zone,” a defined area that is perfect for harboring life in our universe. Readers will find out how scientists are finding habitable planets by using terrestrial and orbiting telescopes to search these regions. Readers will also get to know how extreme zones on Earth are helping scientists redefine their concept of “habitable” and what kind of life we might find. Fascinating full-color photographs and artist renderings from NASA illustrate this fascinating hunt.

With the soothing rhythm of a bedtime story and the scientific wonder of a nature doc, comes a celebration of the moon and all the creatures who rely on its light to find their way home. Under the glow of a shimmering moon, creatures great and small creep out of their dens, using its light to hunt, fend off predators, build their nests or build families. As the moon changes phases these animals adapt their behavior to match its waxing and waning—while human animals look on in wonder. As Earth's closest companion in space, the moon has fascinated humankind for generations, and this nonfiction picture book sheds light on the mysterious ways it affects life on Earth. With luminous illustrations by Jessica Lanan and a lyrical text that is part lullaby and part scientific resource, Thank You, Moon is a treasure for all ages to enjoy.

As a tie-in to the wildly successful History Channel show, here's a book filled with fascinating tales, ancient folklore, and compelling evidence of the role extraterrestrials may have played in human history. What really happened to the dinosaurs? Who actually built the ancient pyramids in Egypt? Are airplanes really as modern as we think they are? This book takes a close look at landmark events throughout history and asks the question: What if aliens were involved? Spanning history, from the earliest of human civilizations to the modern period, this book exposes evidence of the presence of extraterrestrials in some of our most triumphant and devastating moments.

An exciting introduction to astronomy, using recent discoveries and stunning photography to inspire non-science majors about the Universe and science.
