Book Description
"What if?" questions stimulate people to think in new ways, to refresh old ideas, and to make new discoveries. In What If the Earth Had Two Moons, Neil Comins leads us on a fascinating ten-world journey as we explore what our planet would be like under alternative astronomical conditions. In each case, the Earth would be different, often in surprising ways. The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but that won't last forever. Eventually the moons collide, with one extra-massive moon emerging after a period during which Earth sports a Saturn-like ring. This and nine and other speculative essays provide us with insights into the Earth as it exists today, while shedding new light on the burgeoning search for life on planets orbiting other stars. Appealing to adult and young adult alike, this book is a fascinating journey through physics and astronomy, and follows on the author's previous bestseller, What if the Moon Didn't Exist?, with completely new scenarios backed by the latest astronomical research.

Book Description
An astonishing exploration of planet formation and the origins of life by one of the world’s most innovative planetary geologists. In 1959, the Soviet probe Luna 3 took the first photos of the far side of the moon. Even in their poor resolution, the images stunned scientists: the far side is an enormous mountainous expanse, not the vast lava-plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. Fourteen billion years ago, the universe exploded into being, creating galaxies and stars. Planets formed out of the leftover dust and gas that coalesced into larger and larger bodies orbiting around each star. In a sort of heavenly survival of the fittest, planetary bodies smashed into each other until solar systems emerged. Curiously, instead of being relatively similar in terms of composition, the planets in our solar system, and the comets, asteroids, satellites and rings, are bewitchingly distinct. So, too, the halves of our moon. In When the Earth Had Two Moons, esteemed planetary geologist Erik Asphaug takes us on an exhilarating tour through the farthest reaches of time and our galaxy to find out why. Beautifully written and provocatively argued, When the Earth Had Two Moons is not only a mind-blowing astronomical tour but a profound inquiry into the nature of life here—and billions of miles from home.

Book Description
The BBC’s “face of space” explores all things lunar in this comprehensive guide to the folklore, facts, and possible futures of our only natural satellite. Have you ever wondered if there are seasons on the moon or if space tourism will ever become widely accessible? So has Dr. Maggie Aderin-Pocock, astronomer and host of the BBC’s docuseries, The Sky at Night. In this lucidly written guide, Aderin-Pocock takes readers on a fascinating lunar journey. Aderin-Pocock begins with a basic overview—unpacking everything from the moon’s topography and composition to its formation and orbit around the Earth. She examines beliefs held by ancient civilizations, the technology that allowed for the first moon landing, a brief history of moongazing, and how the moon has influenced culture throughout the years. Looking to the future, she delves into the pros and cons of continued space travel and exploration. Throughout the book are sidebars, graphs, and charts to enhance the facts as well as black-and-white illustrations of the moon and stars.
