He has discovered more planets than anyone in history. In this inspiring true story, winner of the American Institute of Physics Award, Geoff Marcy's love of space helped him overcome struggles in his studies until finally he became an astronomer. But he was not on track to make major discoveries. Eventually, he went back to the questions that thrilled him as a boy: Are we alone? Do Earth-like planets orbit the stars in the night sky? It would not be easy to find a planet outside our solar system. Others had tried and failed. But Marcy never gave up. Since 1995, he and his colleagues have discovered nearly half of the 380 known "extrasolar" planets. Stunning paintings transport the reader to the exotic worlds that he and others have found.

Astronomers are on the verge of answering one of our most profound questions: are we alone in the universe? The ability to detect life in remote solar systems is at last within sight, and its discovery—even if only in microbial form—would revolutionize our self-image. Planet Hunters is the rollicking tale of the search for extraterrestrial life and the history of an academic discipline. Astronomer Lucas Ellerbroek takes readers on a fantastic voyage through space, time, history, and even to the future as he describes the field of exoplanet research, from the early ideas of sixteenth-century heretic Giordano Bruno to the discovery of the first exoplanet in 1995 to the invention of the Kepler Space Telescope. We join him on his travels as he meets with leading scientists in the field, including Michel Mayor, who discovered the first exoplanet, and Bill Borucki, principal investigator for NASA’s Kepler mission. Taken together, the experiences, passion, and perseverance of the scientists featured here make the book an exciting and compelling read. Presenting cutting-edge research in a dynamic and accessible way, Planet Hunters is a refreshing look into a field where new discoveries come every week and paradigms shift every year.

In the vastness of space, countless planets exist. Scientists are actively studying as many of them as they can. How many could support life as Earth does? And what other wonderful worlds will our technology find?

Based on the successful Dark Horse graphic novels, this thrilling tale by the author of several bestselling Star Trek novels reunites two of the silver screen's most deadly aliens. Machiko Noguchi, the woman who survived a terrifying battle between the Aliens and Predators in Prey, returns in an action-packed follow-up.

The uplifting, adventure-filled memoir of one groundbreaking scientist’s quest to develop new ways to fight illness and disease through the healing powers of plants. “A fascinating and deeply personal journey.” ­—Amy Stewart, author of Wicked Plants and The Drunken Botanist Traveling by canoe, ATV, mule, airboat, and on foot, Dr. Cassandra Quave has conducted field research everywhere from the flooded forests of the remote Amazon to the isolated mountaintops in Albania and Kosovo—all in search of natural compounds, long-known to traditional healers, that could help save us all from the looming crisis of untreatable superbugs. Dr. Quave is a leading medical ethnobotanist—someone who identifies and studies plants that may be able to treat antimicrobial resistance and other threatening illnesses—helping to provide clues for the next generation of advanced medicines. And as a person born with multiple congenital defects of her skeletal system, she's done it all with just one leg. In The Plant Hunter, Dr. Quave weaves together science, botany, and memoir to tell us the extraordinary story of her own journey.

"The demonic howls continued reverberating inside the sphere. The shrill sounds kept raising and lowering in pitch, as though there were more than one kind of animal within that filmy fog. Each time the thing inside the dome roared, the different tones slowly began modifying themselves into one piercing bellow, slicing through the air. "Hunter grimly whispered, 'Don't watch. This is the part where something really bad happens.' " On the eve of final exams, the remarkably young, yet remarkably talented Hunter is sent out to the uncivilized ends of the universe to disarm an up-and-coming terrorist organization. In the midst of his absence, an unknown alien species descends upon the Universally-Credited Tactics Academy, the most advanced center for training in interstellar warfare, industrial espionage, and technological sciences. In the space of a single night, this hostile force takes control of the galaxy's best kept military secrets. When these creatures uncover information surrounding the source of Hunter's strength, they stop at nothing to destroy him. Before Hunter can face this new threat, though, he must come to terms with a secret buried deep inside him; a secret that could lead to the destruction of everything and everyone Hunter holds dear.

Aliens are big in America. Whether they’ve arrived via rocket, flying saucer, or plain old teleportation, they’ve been invading, infiltrating, or inspiring us for decades, and they’ve fascinated moviegoers and television watchers for more than fifty years. About half of us believe that aliens really exist, and millions are convinced they’ve visited Earth. For twenty-five years, SETI has been looking for the proof, and as the program’s senior astronomer, Seth Shostak explains in this engrossing book, it’s entirely possible that before long conclusive evidence will be found. His informative, entertaining report offers an insider’s view of what we might realistically expect to discover light-years away among the stars. Neither humanoids nor monsters, says Shostak; in fact, biological intelligence is probably just a precursor to machine beings, enormously advanced artificial sentients whose capabilities and accomplishments may have developed over billions of years and far exceed our own. As he explores what, if anything, they would tell us and what their existence would portend for humankind and the cosmos, he introduces a colorful cast of characters and provides a vivid, state-of-the-art account of the past, present, and future of our search for extraterrestrial intelligence.
