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
From writer Stacy McAnulty and illustrator Stevie Lewis, Moon! Earth's Best Friend is a light-hearted nonfiction picture book about the formation and history of the moon—told from the perspective of the moon itself. Meet Moon! She's more than just a rock—she’s Earth’s rock, her best friend she can always count on. Moon never turns her back on her friend (literally: she's always facing Earth with the same side!). These two will stick together forever. With characteristic humor and charm, Stacy McAnulty channels the voice of Moon in this next celestial "autobiography" in the Our Universe series. Rich with kid-friendly facts and beautifully brought to life by Stevie Lewis, this is an equally charming and irresistible companion to Earth! My First 4.54 Billion Years and Sun! One in a Billion.

Book Description
Former NASA Astronaut Harrison Schmitt advocates a private, investor-based approach to returning humans to the Moon—to extract Helium 3 for energy production, to use the Moon as a platform for science and manufacturing, and to establish permanent human colonies there in a kind of stepping stone community on the way to deeper space. With governments playing a supporting role—just as they have in the development of modern commercial aeronautics and agricultural production—Schmitt believes that a fundamentally private enterprise is the only type of organization capable of sustaining such an effort and, eventually, even making it pay off.

Book Description
Earth is not the only planet with intelligent human life. For many millennia, advanced humans from Completed Worlds have monitored the technological development of humans on other less advanced planets across the universe, including Earth. Each Developing World always has five Watchers from Completed Worlds, who are assigned to live on the planet and monitor its progress. The Watchers work under the strict direction of a Universal MAXIM to anonymously observe and report and never interfere with the native humans. Earth was Developing at a great pace until a band of Universal terrorists, known as Takers, damaged the Earth with large asteroids, flooding the planet and killing nearly all its population. The largest asteroid in the attack was miraculously caught into the Earth's orbit, becoming a second moon. Rogue Watcher, the next installment of the Second Moon Trilogy, picks up where Alpine Tide left off. The stakes are higher than ever as eighteen-year-old Miriam Madsen and her fellow survivors face new threats from across the Universe. To avoid their certain destruction, Watcher 3 of Earth, known locally as Spence, will stop at no length to protect Miriam, the woman he loves--even if it means going rogue. Explore the Second Moon Trilogy online at www.secondmoontrilogy.com for exclusive content, author commentary, and a sneak peek into the last installment of the trilogy.
