What does it take to consider a planet potentially habitable? If a planet is suitable for life, could life be present? Is life on other planets inevitable? Searching for Habitable Worlds answers these questions and provides both the general public and astronomy enthusiasts with a richly illustrated discussion of the most current knowledge regarding the search for extrasolar planets. Nearly everyone wants to know if we are alone in the universe. This book might not have the answers, but shows where we should look. This book is a fun and accessible book for everyone from middle schoolers to amateur astronomers of all ages. The use of non-technical language and abundant illustrations make this a quick read to inform everyone about the latest movement in the search for other planets that we might be able to inhabit. After a brief discussion on why humans are hard-wired to be curious, and to explore the unknown, the book describes what extrasolar planets are, how to detect them, and how to pin down potential targets. In addition, a data-driven list of the best candidates for habitability is profiled and the next generation of exoplanet-hunting scientific instruments and probes are identified.

Visual Astronomy introduces the basics of observational astronomy, a fundamentally limitless opportunity to learn about the universe with your unaided eyes or with tools such as binoculars, telescopes, or cameras. The book explains the essentials of time and coordinate systems and their use in basic observations of the night sky. Readers will learn how to use widely accessible resources to determine what is visible (and when it is visible) from their particular location. Distinct attention is paid to the dependence of the appearance and motion on the observer's location, by extending the discussion to include various latitudes in both the Northern and Southern Hemispheres. This approach provides a better understanding of the night sky and makes the material more interesting and relevant around the world, not just in North America. You don't need any mathematical skill or technical knowledge to quickly grasp the concepts of basic astronomy, nor do you need expensive equipment to look up at the night sky and understand what you see. If you do have or can access a telescope, Visual Astronomy will teach you the fundamentals of its use and how to get the best views possible. Links to major telescope facilities around the world; current and past space missions; links to free sky simulation applications; and ideas for observation projects make this an excellent learning tool for the new hobbyist or for teachers who wish to show their students why visual astronomy is a lifetime love for millions.

Space and Space Travel is a comprehensive introductory overview of subject matter related to exploration of the solar system. After an initial discussion of energy, power, and the atom, the book explores the Sun and its impact on planets and the space environment, the conditions in space, the fundamentals of space travel, and planetary destinations. Specific topics include the solar interior and atmosphere, space plasma environments and weather, advanced propulsion, the inner solar system, and asteroids and beyond. Photographs, charts, and graphs support the text and enhance learning. Space and Space Travel is broadly based, and can be used in classes that discuss planetary science, space science, space technology, and human space flight. It is suitable for junior and senior level high school courses, as well as survey courses at the university level. The book is also an excellent jumping off point for technical classes that explore a specific topic in detail, but require general background knowledge.

What's in the dark? Countless generations have gazed up at the night sky and asked this question--the same question that cosmologists ask themselves as they study the universe.
The answer turns out to be surprising and rich. The space between stars is filled with an exotic substance called "dark matter" that exerts gravity but does not emit, absorb, or reflect light. The space between galaxies is rife with "dark energy" that creates a sort of cosmic antigravity causing the expansion of the universe to accelerate. Together, dark matter and dark energy account for 95 percent of the content of the universe. News reporters and science journalists routinely talk about these findings using terms that they assume we have a working knowledge of, but do you really understand how astronomers arrive at their findings or what it all means?
Cosmologists face a conundrum: how can we study substances we cannot see, let alone manipulate? A powerful approach is to observe objects whose motion is influenced by gravity. Einstein predicted that gravity can act like a lens to bend light. Today we see hundreds of cases of this--instances where the gravity of a distant galaxy distorts our view of a more distant object, creating multiple images or spectacular arcs on the sky. Gravitational lensing is now a key part of the international quest to understand the invisible substance that surrounds us, penetrates us, and binds the universe together.
"A Ray of Light in a Sea of Dark Matter" offers readers a concise, accessible explanation of how astronomers probe dark matter. Readers quickly gain an understanding of what might be out there, how scientists arrive at their findings, and why this research is important to us. Engaging and insightful, Charles Keeton gives everyone an opportunity to be an active learner and listener in our ever-expanding universe.

What was our planet like in years past? How has our civilization affected Earth and its ecology? Harvesting Space for a Greener Planet, the Second Edition of Paradise Regained: The Regreening of the Earth, begins by discussing these questions, and then generates a scenario for the restoration of Earth. It introduces new and innovative ideas on how we could use the Solar System and its resources for terrestrial benefit. The environmental challenges that face us today cannot be resolved by conservation and current technologies alone. Harvesting Space highlights the risk of humankind's future extinction from environmental degradation. Population growth, global climate change, and maintaining sustainability of habitats for wildlife are all considered, among other issues. Rather than losing heart, we need to realize that the solutions to these problems lie in being good stewards of the planet and in the development of space. Not only will the solutions offered here avert a crisis, they will also provide the basis for continued technological and societal progress. Tapping the resources of near-Earth asteroids will lead to methods of diverting those asteroids that threaten Earth. Space-based terrestrial power generation systems will work synergistically with Earth-based conservation. This book needs to be read urgently and widely, if we are to save ourselves from environmental disaster, reduce the risk of catastrophic cosmic impacts, and build a prosperous and sustainable future for all the creatures of Earth.

Adaptive optics (AO) corrects distortions created by atmospheric turbulence and delivers diffraction-limited images on ground-based telescopes. The vastly improved spatial resolution and sensitivity has been utilized for studying everything from the magnetic fields of sunspots upto the internal dynamics of high-redshift galaxies. This thesis about AO science from small and large telescopes is divided into two parts: Robo-AO and magnetar kinematics. In the first part, I discuss the construction and performance of the world's first fully autonomous visible light AO system, Robo-AO, at the Palomar 60-inch telescope. Robo-AO operates extremely efficiently with an overhead

This book is about the history and future of life and the universe, written at a level that any educated lay-person can understand and enjoy. It describes our place in time and space, how we got here and where we are going. It will take you on a journey from the beginning of time to the end of the universe to uncover our origins and reveal our destiny. It will explain how mankind acquired this knowledge starting from the beginning of civilization when the ancient Greeks first began to ask questions about the nature of the world around them.

Ben Moore takes us on a path of discovery that connects astrophysics with subjects as varied as biology, neuroscience and evolution; from the origin of atoms to how stars shine and die, from ants and elephants to space travel and extra-terrestrial life. But as our universe grows older and its stars fade away and stop shining, can life continue for eternity or is all life destined for complete extinction? And what is the purpose of all of this anyway?

On the German edition:
"With his public talks and his new book "Elefanten im All" the Brit is on his way of becoming a popstar of science. Moore has a story to tell. The story of everything. From the beginning to the end of our existence. And he does so with esprit and catching passion." Rico Bandle, Weltwoche, 1. November 2012

"The kind of book you come across only every few years." Artur K. Vogel, Der Bund, September 2012"

In 2005, Palla & Baraffe proposed that brown dwarfs and very low mass stars (

50 Things to See with a Small Telescope is composed of the go-to objects observed at public stargazing events all over the Northern Hemisphere. People of all ages frequently ask, "How did you find that so quickly?" Well, this book will explain just that The planets in our solar system, the International Space Station, sunspots, birds, nebula, airplanes, and comets are just some of the items that his book will help you find If you have been having difficulties enjoying your small telescope, this book is for you. There is something interesting about pretty much everything in outer space and it is exciting how many pop-culture references are derived from things in the night sky Viewing the stars referenced in Star Trek, or talking about a character in Harry Potter named after a constellation, is just another way to make stargazing that much more fun I am very excited to share my knowledge of astronomy and I am sure you will enjoy this book for years to come. By working through the 50 items in this book you will achieve a well-rounded understanding of amateur astronomy.
