What If the Earth Had Two Moons? PDF Author: Neil F. Comins
Publisher: Macmillan
ISBN: 142995793X
Category : Science
Languages : en
Pages : 506

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.

When the Earth Had Two Moons

When the Earth Had Two Moons PDF Author: Erik Asphaug
Publisher: HarperCollins
ISBN: 0062657941
Category : Science
Languages : en
Pages : 424

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.

Natural Satellites

Natural Satellites PDF Author: Ron Miller
Publisher: Twenty-First Century Books ™
ISBN: 1728427495
Category : Young Adult Nonfiction
Languages : en
Pages : 104

Book Description
For centuries, astronomers have placed a special interest on the other planets of the solar system. But with the advent of spacecraft and the tremendous missions undertaken by the Voyager and Cassini probes, astronomers have discovered that the natural satellites of the planets—the solar system's moons—are some of the most extraordinary places imaginable. There are moons with towering geysers, erupting volcanoes, and subterranean oceans of warm, mineral-rich water. Some of the highest mountains and deepest canyons can be found on the moons. There are moons that have shattered into pieces and then reassembled. There is even a moon where it rains rocket fuel. Recently, scientists have turned to the moons for answers in their investigations of the origins of the solar system and the evolution of life on our own planet. Featuring full-color, scientifically accurate illustrations by NASA artist Ron Miller, Natural Satellites: The Book of Moons chronicles these investigations and the questions we have yet to answer in our exploration of the solar system's moons.
