Why write a book about the stars? Of what use is their study? This book covers this ground with a number of anecdotes arising from the author's almost 60 years' experience as a research scientist who has worked with some of the largest telescopes in the world. The text exposes much of what is glossed over in the canned information that the public get and holds nothing back with respect to uncertainties within the subject. People want answers, want somehow to be reassured that someone out there has a handle on things. This book details the basis for our knowledge of the universe, warts and all, and offers important insights as to where the science is going.

Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out.

The landscapes of the American Southwest - the Grand Canyon, Monument Valley, the Sedona red rocks - have long filled humans with wonder about nature. This is the home of Lowell Observatory, where astronomers first discovered evidence that the universe is expanding; Meteor Crater, where Apollo astronauts trained for the moon; and Native American tribes with their own ancient, rich ways of relating to the cosmos. With the personal, poetic style of the very best literary nature writing, Don Lago explores how these landscapes have offered humans a deeper sense of connection with the universe. While most nature writing never leaves the ground, Lago is one of the few writers who has applied it to the universe, seeking ties between humans and the astronomical forces that gave us birth. Nowhere else in the world is the link between earth and sky so powerful. Lago witnesses a solar eclipse over the Grand Canyon, climbs primeval volcanos, and sees the universe in tree rings. Through ageless Native American ceremonies, modern telescopes, and even dreams of flying saucers, Lago, who is not only a poet but a true philosopher of science, strives to find order and meaning in the world and brings out the Southwest's beauty and mystery.

Ever since Galileo glimpsed the moons of Jupiter through his tiny telescope, astronomers have striven to understand how the universe is constructed and how it evolves. Every increase in the size and power of telescopes has led to new discoveries. Within the last century, telescopes have enabled us to learn about pulsars, quasars, gamma-ray bursters, black holes, and the acceleration of the universe's expansion.

An Acre of Glass describes how recent innovations in telescope technology have led to the construction of giant, ground-based observatories and to an explosive development of astronomy. Today, telescopes with mirrors 30, 50, and even 100 meters in diameter are being built. Optical interferometers that cover an acre of ground are observing every night. J. B. Zirker shows us how telescopes past, present, and future are built and describes the exciting science they reveal -- from planets beyond our solar system to supermassive black holes at the core of distant galaxies.

For every striking image revealed through these enormous telescopes, technicians and scientists must overcome unique and incredible challenges. How many pack animals does it take to get a telescope to the top of a mountain? How do you make the shape of a 6-foot-wide mirror accurate to within a 1,000th the thickness of a human hair? In clear and accessible language, Zirker answers these questions and more, providing fascinating technical detail about how a telescope is made and what the next generation can hope to see.

In this vibrant, eye-opening tour of milestones in the history of our universe, Chris Impey guides us through space and time, leading us from the familiar sights of the night sky to the dazzlingly strange aftermath of the Big Bang. What if we could look into space and see not only our place in the universe but also how we came to be here? As it happens, we can. Because it takes time for light to travel, we see more and more distant regions of the universe as they were in the successively greater past. Impey uses this concept "look-back time" to take us on an intergalactic tour that is simultaneously out in space and back in time. Performing a type of cosmic archaeology, Impey brilliantly describes the astronomical clues that scientists have used to solve fascinating mysteries about the origins and development of our universe. The milestones on this journey range from the nearby to the remote: we travel from the Moon, Jupiter, and the black hole at the heart of our galaxy all the way to the first star, the first ray of light, and even the strange, roiling conditions of the infant universe, an intense and volatile environment in which matter was created from pure energy. Impey gives us breathtaking visual descriptions and also explains what each landmark can reveal about the universe and its history. His lucid, wonderfully engaging scientific discussions bring us to the brink of modern cosmology and physics, illuminating such mind-bending concepts as invisible dimensions, timelessness, and multiple universes. A dynamic and unforgettable portrait of the cosmos, How It Began will reward its readers with a deeper understanding of the universe we inhabit as well as a renewed sense of wonder at its beauty and mystery."

When astronomers today look up at the night sky they picture a spectacular and infinite universe--full of pulsars, quasars, and black holes and ruled by arcane laws of space and time. Once, ancient astronomers looked up and saw only points of light tracing calm movements across the heavens. But they too were moved to wonder about the meaning of what they saw. In Astronomy through the Ages, Sir Robert Wilson tells the story of how our understanding of the universe has evolved through history--of how the sedate and stable star field of ancient times has been replaced by the vast and explosive universe we know today. Wilson, one of the most distinguished astronomers of the twentieth century, begins by tracing the astronomical studies of the ancient Babylonians, Egyptians, and Greeks and reviews important early contributions from India, China, and the Islamic world. He explains the development of the sun-centered model of the universe in Renaissance Europe. He then tells how the development of the telescope, photography, and spectroscopy pushed back the limits of the observable universe and eventually brought astronomy into the twentieth century. Finally, he describes the rapid advances in radio and space astronomy and other methods over the past fifty years that have ushered in a new "golden age" of astronomy. These advances have not only allowed observation of deep space but also enabled scientists to unlock the secrets of the universe itself from its origin to its possible fate. Wilson himself has played an important role in these discoveries as the developer of one of the most successful astronomical satellites ever launched, the International Ultraviolet Explorer. While focusing on the human side of astronomical discovery, Wilson also provides readers with a basic understanding of difficult concepts, explaining relativity and quantum mechanics without using technical language or mathematics. Remarkable in its scope and clarity,Astronomy through the Ages provides an accessible view of historical discoveries and modern advances and shows why excitement about astronomy is even greater today than when Galileo first gazed in wonder at the rings of Saturn.
