Ice Dwarfs

A tour of the ice dwarfs from Pluto and beyond. Learn how amazing space really is.

Ever since the serendipitous discovery of planet Uranus in 1871, astronomers have been hunting for new worlds in the outer regions of our solar system. This exciting and ongoing quest culminated recently in the discovery of hundreds of ice dwarfs in the Kuiper belt, robbed Pluto from its ‘planet’ status, and led to a better understanding of the origin of the solar system. This timely book reads like a scientific ‘who done it’, going from the heights of discovery to the depths of disappointment in the hunt for ‘Planet X’. Based on many personal interviews with astronomers, the well-known science writer Govert Schilling introduces the heroes in the race to be the first in finding another world, bigger than Pluto.

This book presents 41 selected articles written by leading researchers from the Vernadsky Institute of Geochemistry and Analytical Chemistry, part of the Russian Academy of Sciences. The articles are grouped by the following topics: (1) Geochemistry, (2) Meteoritics, Cosmochemistry, Lunar and Planetary Sciences, (3) Biogeochemistry and Ecology, and (4) Analytical Chemistry, Radiochemistry, and Radioecology. The articles present recent experimental data, theoretical investigations, critical reviews, the results of computer modeling in the above-mentioned fields. Intended to provide a scientific “snapshot” of the institute, the book also includes content on its history, main scientific achievements and current goals, together with detailed descriptions of its 25 laboratories and three museums so as to promote new international collaborations. Given its scope, the book will be of interest to all scientists and graduate students working in the areas of geochemistry, analytical chemistry and radiochemistry, earth and environmental sciences, biogeosciences, meteoritics and planetary science, and to those seeking new collaboration opportunities in these areas in Russia.

Although there is a chance that certain planets may be habitable for life, the moons of planets might have even more to offer. The icy moons of Jupiter, Saturn, Uranus and Neptune have taught us important lessons about new volcanic forms—cryovolcanism—and the bizarre landscapes sculpted by those erupting geysers. Glaciers, ice mountains, and vast canyons mold the faces of these worlds of ice and thunder. Yet, many ice moons and dwarf planets, including Ceres and Pluto, are in fact sea worlds, hiding deep oceans beneath their ice crusts. This book explores the frozen worlds beyond Mars, delving into the interior forces of migrating ice diapirs, seafloor volcanism and tidal friction, which help form the landscapes found above and biologically friendly environs buried below. It covers the latest research in the field and includes interviews with today’s foremost authorities, including astrobiologists Chris McKay (NASA Ames), Ralph Lorenz (Johns Hopkins Applied Physics Laboratory) and Karl Mitchell (Jet Propulsion Laboratory). Original art by the author enhances the concepts explored in the text, recreating some of the most remarkable landscapes on icy planets and moons.

Astronomical concepts can be truly hard to comprehend, especially those of planetary sizes and distances from Earth and from each other. These concepts are made more comprehensible by the group of illustrations in this book, which put scale extraterrestrial objects side by side with objects on Earth we can more easily relate to. For example, study the pictures of Earth floating above Jupiter’s Great Red Spot and the asteroid Itokawa resting beside Toronto’s CN Tower. These mind-bending images bring things better into perspective and will help you understand the size and scale of our Solar System. In later chapters, you will be told how close the visionaries of the past came to guessing what today’s explorers would find. Astronomer/painter Lucien Rudaux’s masterpieces of Mars dust storms anticipated Viking and Mars rover images by nearly a century. Space artist Ludek Pesek envisioned astronauts setting up camp on the lunar surface in scenes hauntingly similar to photos taken by Apollo astronauts decades later. But the real benefit of this work is in better grasping the nature of our universe -- how big it is, now large it is, and how we fit into it.

This thought-provoking book looks at the nature of red dwarf systems as potential homes for life. Realistically, what are the prospects for life on these distant worlds? Could life evolve and survive there? How do these planetary surfaces and geologies evolve? How would life on a planet orbiting a red dwarf differ from life on Earth? And what are the implications for finding further habitable worlds in our galaxy? The author provides readers with insight into the habitability of planets and how this changes as time progresses and the central star evolves. Since the previous 2013 edition Under a Crimson Sun, there has been a rise in newly discovered planets orbiting red dwarfs, accompanied by controversial areas of research that test what we think we know about these systems. This revised edition delves into the wealth of new material uncovered since that date. It explains the often conflicting results and analyses put forward and clarifies our understanding of these exciting new worlds. The chapters explore the full width of relevant scientific discovery and speculation on the potential for red dwarf planets to host life. New content includes improved atmospheric models, new understandings of the impact of stellar radiation on the atmosphere of red dwarf worlds, tidal-locking, and comparisons with terrestrial geology and climate.

In a mind-bogglingly vast universe, our solar system feels like a comparatively cozy home, perched out on one of the outer arms of the spiral Milky Way galaxy. Formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud, it is comprised of eight terrestrial and gaseous planets, several hundred dwarf planets, nearly five hundred moons, and other small bodies such as asteroid belts, comets, and dust clouds. Chock full of breathtaking satellite imagery, meticulously detailed computer renderings, diagrams, infographics, and the latest discoveries, readers are treated to a wealth of mind-blowing facts, images, and data. They will gain familiarity with our home solar system while also becoming curious about what lies beyond our threshold in deep space.
