Decades ago, astronauts brought back 850 pounds of rocks from their lunar journeys; the U.S. gave some away as “goodwill” gifts to the world’s nations. Over time, many of them disappeared, stolen or lost in the aftermath of political turmoil, and offered for millions on the black market. Gutheinz, first as a NASA investigator and then the leader of a intrepid group of students, has dedicated his life to getting them back. Author Joe Kloc tells a wild story of geopolitics, crime, science, and one man’s obsession with keeping the moon out of the wrong hands.

    She is studying the planets in school and loves Roman mythology. "It might be called Pluto," she says, thinking of the dark underworld. Grandfather loves the idea and contacts his friend at London's Royal Astronomical Society, who writes to scientists at the Lowell Observatory in Massachusetts, where Pluto was discovered. After a vote, the scientists agree unanimously: Pluto is the perfect name for the dark, cold planet. Here is a picture book perfect for STEM units and for all children--particularly girls--who have ever dreamed of becoming a scientist.

    But how do seeds get to the perfect place to grow? This exploration of seed dispersal covers a wide range of seeds and the creatures that help them move, from a coconut seed floating on waves to an African grass seed rolled by a dung beetle, to a milkweed seed floating on the wind.

    These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century? Here, too, is a rare, private glimpse of Sagan's thoughts about love, death, and God as he struggled with fatal disease. Ever forward-looking and vibrant with the sparkle of his unquenchable curiosity, Billions & Billions is a testament to one of the great scientific minds of our day.

    A playful, entertaining, and mind-bending introduction to modern physics, it's already a major bestseller in Italy and the United Kingdom. Carlo Rovelli offers surprising—and surprisingly easy to grasp—explanations of general relativity, quantum mechanics, elementary particles, gravity, black holes, the complex architecture of the universe, and the role humans play in this weird and wonderful world. He takes us to the frontiers of our knowledge: to the most minute reaches of the fabric of space, back to the origins of the cosmos, and into the workings of our minds. “Here, on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and the beauty of the world,” Rovelli writes. “And it’s breathtaking.”

    In this lively and compact introduction, astrophysicist Andrew King reveals how the laws of physics force stars to evolve, driving them through successive stages of maturity before their inevitable and sometimes spectacular deaths, to end as remnants such as black holes. The book shows how we know what stars are made of, how gravity forces stars like the Sun to shine by transmuting hydrogen into helium in their centers, and why this stage is so long-lived and stable. Eventually the star ends its life in one of just three ways, and much of its enriched chemical content is blasted into space in its death throes. Every dead star is far smaller and denser than when it began, and we see how astronomers can detect these stellar corpses as pulsars and black holes and other exotic objects. King also shows how astronomers now use stars to measure properties of the Universe, such as its expansion. Finally, the book asks how it is that stars form in the first place, and how they re-form out of the debris left by stars already dead. These birth events must also be what made planets, not only in our solar system, but around a large fraction of all stars.

    A total eclipse of the Sun will be visible from within a narrow corridor that traverses the United States. The path of the Moon's umbral shadow will begin in the northern Pacific and cross the USA from west to east from Oregon to South Carolina. The Moon's penumbral shadow will produce a partial eclipse visible from most of North America. In fact, the 2017 full eclipse is such an important sky event that sky watchers in Europe are already planning trips to view it. 2017 Guide to the Night Sky provides all of the information needed to view this exciting eclipse and track its path. The time zones and transit of the eclipse will be noted inside the book's jacket for quick and easy reference.The night sky makes for exciting viewing any time of the year, and 2017 Guide to the Night Sky is the ideal guide to help amateur astronomers find their way for the entire 12 months. With monthly charts and other diagrams set for a latitude of 40 degrees North, it shows how the visible stars change from month to month and includes the many sky events that occur throughout the year. It is highly practical for beginning sky gazers because the objects and events may be observed with the naked eye, or nothing more complicated than a pair of binoculars.The month-by-month guides include sky activity charts and moon calendars; meteors (with dates of showers, including hourly rate of radiants); the Planets; ecliptic charts; diagrams of interesting events; plus sky and constellation maps throughout.An appendix includes a full glossary; the Greek Alphabet; the constellation genitives, abbreviations and English names; a table of common asterisms; further information; recommended astronomy journals, societies, institutions and organizations; software, and internet sources.Especially useful for beginning sky watchers, this guide will be fully updated to 2017. Its small and light format makes it the ideal portable reference for backyard astronomers.

    In over fifty dramatic, full-color photographs and an easy-to-read text, award-winning author Seymour Simon takes you on a fascinating tour of the nine planets, dozens of moons, and thousands of asteroids, meteoroids, and comets that travel around our sun.First, Simon explores the star at the center of our Solar System -- from the constant nuclear explosions at its core to the giant storms on its surface as geysers of flaming gas over a hundred thousand miles long rise and fall in just a few hours.You will also learn about the four rocky inner planets, from airless Mercury to fiery Venus, her sister planet, Earth, and mysterious Mars. Then join the thrilling Voyager missions to explore the four gaseous outer planets: gigantic Jupiter, ringed Saturn, tilted Uranus -- the planet "lying on its side" -- and windy Neptune. You will finish your journey at distant Pluto, then visit the asteroid belt and examine comets, the "dirty snowballs" in space.A companion volume to Simon's landmark series of individual books about each of the planets, the sun, stars, and other space sights, Our Solar System will introduce you to some of the most amazing mysteries in the universe.

    Born the youngest daughter of a poor family in Hanover, Germany, she was scarred from smallpox, stunted from typhus and used by her parents as a scullery maid. But when her favorite brother, William, left for England, he took her with him. The siblings shared a passion for stars, and together they built the greatest telescope of their age, working tirelessly on star charts. Using their telescope, Caroline discovered fourteen nebulae and two galaxies, was the first woman to discover a comet, and became the first woman officially employed as a scientist by no less than the King of England! The information from the Herschels star catalogs is still used by space agencies today.

    Vera Rubin was one of the astronomers who discovered and named dark matter, the thing that keeps the universe hanging together. Throughout her career she was never taken seriously as a scientist because she was one of the only female astronomers at that time, but she didn’t let that stop her. She made groundbreaking and incredibly significant discoveries that scientists have only recently been able to really appreciate—and she changed the way that we look at the universe.

    They infinitely warp space and time, allowing nothing to escape: not matter, not even light. They are stellar corpses that have crushed themselves into oblivion, seemingly suspending the traditional laws of physics. The Big bang may have peppered the universe with primordial black holes, as small as protons but as massive as mountains. The universe itself may be disappearing into the final black hole. Black holes (BHs) and their warping effect on spacetime are described, beginning with a discussion on stellar evolution that includes white dwarfs, supernovas and neutron stars. The structure of static, rotating, and electrically charged BHs are considered, as well as the general theory of relativity, quantum mechanics, the Einstein-Rosen bridge, and wormholes in spacetime. Attention is also given to gravitational lenses, various space geometries, quasars, Seyfert galaxies, supermassive black holes, the evaporation and particle emission of BHs, and primordial BHs, including their temperature and lifetime. The author's engrossing, non-technical explanations are enhanced by numerous illustrations.

    Moon never turns her back on her friend (literally: she's always facing Earth with the same side!). These two will stick together forever.
