Oceans were long thought to exist in all corners of the Solar System, from carbonated seas percolating beneath the clouds of Venus to features on the Moon's surface given names such as "the Bay of Rainbows" and the "Ocean of Storms." With the advent of modern telescopes and spacecraft exploration these ancient concepts of planetary seas have, for the most part, evaporated. But they have been replaced by the reality of something even more exotic. For example, although it is still uncertain whether Mars ever had actual oceans, it now seems that a web of waterways did indeed at one time spread across its surface. The "water" in many places in our Solar System is a poisoned brew mixed with ammonia or methane. Even that found on Jupiter's watery satellite Europa is believed similar to battery acid. Beyond the Galilean satellites may lie even more "alien oceans." Saturn's planet-sized moon Titan seems to be subject to methane or ethane rainfall. This creates methane pools that, in turn, become vast lakes and, perhaps, seasonal oceans. Titan has other seas in a sense, as large shifting areas of sand covering vast plains have been discovered. Mars also has these sand seas, and Venus may as well, along with oceans of frozen lava. Do super-chilled concoctions of ammonia, liquid nitrogen, and water percolate beneath the surfaces of Enceladus and Triton? For now we can only guess at the possibilities. 'Alien Seas' serves up part history, part current research, and part theory as it offers a rich buffet of "seas" on other worlds. It is organized by location and by the material of which various oceans consist, with guest authors penning specific chapters. Each chapter features new original art depicting alien seas, as well as the latest ground-based and spacecraft images. Original diagrams presents details of planetary oceans and related processes.

Sometime in the not-too-distant future ... unbeknownst to Earth, the Galaxy is home to a number of spacefaring societies. This confederation enforces a strict protocol forbidding any contact with civilizations that have not yet achieved both a substantial spacefaring capability and sufficient maturity to control the technology explosion before triggering their own extinction. While this policy is intended to only bring in peaceful new members, matters change entirely when the confederation is threatened by some unknown entity - is the menace real or imagined? The confederation decides to break with the rules and sends a delegate to Earth to hire one of the supposedly belligerent Earthlings to investigate and to revive the confederation's long-unused starfleet. The Earthman agrees, but demands a high price: should he succeed, the confederation will have to accept Earth as a new member. As the threat becomes ever more acute, the question soon becomes which mission will prove harder - saving the confederation or convincing it to accept the deal! The extensive appendix, written in non-technical language, reviews the scientific and technological topics underlying the plot - ranging from the Fermi paradox, space travel and artificial/collective intelligence to theories on possible universal convergences in technological and biological development.

This book, written for a general readership, reviews and explains the three-body problem in historical context reaching to latest developments in computational physics and gravitation theory. The three-body problem is one of the oldest problems in science and it is most relevant even in today's physics and astronomy. The long history of the problem from Pythagoras to Hawking parallels the evolution of ideas about our physical universe, with a particular emphasis on understanding gravity and how it operates between astronomical bodies. The oldest astronomical three-body problem is the question how and when the moon and the sun line up with the earth to produce eclipses. Once the universal gravitation was discovered by Newton, it became immediately a problem to understand why these three-bodies form a stable system, in spite of the pull exerted from one to the other. In fact, it was a big question whether this system is stable at all in the long run. Leading mathematicians attacked this problem over more than two centuries without arriving at a definite answer. The introduction of computers in the last half-a-century has revolutionized the study; now many answers have been found while new questions about the three-body problem have sprung up. One of the most recent developments has been in the treatment of the problem in Einstein's General Relativity, the new theory of gravitation which is an improvement on Newton's theory. Now it is possible to solve the problem for three black holes and to test one of the most fundamental theorems of black hole physics, the no-hair theorem, due to Hawking and his co-workers.

Cometography is a multi-volume catalog of every comet observed throughout history. Volume 3 provides a complete discussion of every comet seen during the first part of the twentieth century. Cometography uses the most reliable orbits known to determine the distances from the Earth and Sun at the time a comet was discovered and last observed, as well as the largest and smallest angular distance to the Sun, most northerly and southerly declination, closest distance to the Earth, and other details to enable the reader to understand the physical appearance of each well-observed comet. The book also provides non-technical details to help the reader better appreciate how the comet may have influenced various cultures at the time of its appearance. Cometography will be valuable to historians of science as well as providing amateur and professional astronomers with a definitive reference on comets through the ages.

This book, now in a revised and updated second edition, explains the theory of special and general relativity in detail without approaching Einstein's life or the historical background. The text is formulated in such a way that the reader will be able to understand the essence intuitively, and new sections have been added on time machines, the twin paradoxes, and tensors. The first part of the book focuses on the essentials of special relativity. It explains the famous equivalence between mass and energy and tells why Einstein was able to use the theory of electrodynamics as a template for his "electrodynamics of moving bodies". General relativity is then addressed, mainly with the help of thought experiments. Reference is made to the previously introduced special relativity and the equivalence principle and, using many figures, it is explained how space-time is bending under gravity. The climax of the book is the Einstein equation of gravity, which describes the way in which matter bends space-time. The reader is shown how to obtain the famous Schwarzschild solution. Moreover, the book presents a numerically correct and yet intuitive explanation of the classic effects such as light bending and the advance of the perihelion. The book concludes by explaining the Friedmann model of the big bang and why the theory of gravity does not fit with quantum theory.

Comet presents the amazing story of the Rosetta space probe and its interstellar voyage to the comet Tchoury. Its mission - to find clues to the origins of our solar system and the emergence of life on Earth. Following a ten-year voyage and a journey spanning millions of kilometres through our Solar System, the Rosetta entered the comet's orbit. Its lander, Philae - a miniature science laboratory - landed directly on Tchoury's surface and was able to take the photographs presented here. This triumph of scientific endeavour brought back a raft of incredible new photographs, the best of which are featured here. The book is built around the various phases in Rosetta's journey: leaving Earth, breaching its atmosphere and watching the lights of home recede; skirting the Moon and coming close to Mars; plunging into the cosmos' starry void and approaching the comet; and, finally, landing on Tchoury. The photographs are accompanied by a text that reflects on the objectives of the mission and the accomplishment of such a technological feat for humanity. Detailed captions provide the reader with accessible scientific information, enabling them to get to the heart of the subject.

In this book, Giovanni Bignami, the outstanding Italian scientist and astronomer, takes the reader on a journey through the "seven spheres", from our own planet to neighboring stars. The author offers a gripping account of the evolution of Homo Sapiens to the stage where our species is developing capabilities, in the form of new energy propulsion systems, that will enable us to conquer space. The reader will learn how we first expanded our activities to reach beyond our planet, to the Moon, and how nuclear energy, nuclear fusion, and matter-antimatter annihilation will enable us to extend our exploration. After Mars and Jupiter we shall finally reach the nearest stars, which we now know are surrounded by numerous planets, some of which are bound to be habitable. The book includes enticing descriptions of such newly discovered planets and also brings alive key historical characters in our story, such as Jules Verne and Werner von Braun.

The word "landscape" can mean picture as well as natural scenery. Recent advances in space exploration imaging have allowed us to now have landscapes never before possible, and this book collects some of the greatest views and vistas of Mars, Venus's Titan, Io and more in their full glory, with background information to put into context the foreign landforms of our Solar System. Here, literally, are 'other-worldly' visions of strange new scenes, all captured by the latest technology by landing and roving vehicles or by very low-flying spacecraft. There is more than scientific interest in these views. They are also aesthetically beautiful and intriguing, and Dr. Murdin in a final chapter compares them to terrestrial landscapes in fine art. Planetary Vistas is a science book and a travel book across the planets and moons of the Solar System for armchair space explorers who want to be amazed and informed. This book shows what future space explorers will experience, because these are the landscapes that astronauts and space tourists will see.

Sets out a simple month-by-month program to reveal all of the night sky's biggest and most beautiful secrets in just one year - and with only a few hours of stargazing each month By investing just an hour a week and $50 in binoculars, it's possible to learn a few simple techniques and quickly gain a real insight into the night sky's ever-changing patterns - and what they tell us about Earth, the seasons and ourselves. Searching more for a learned appreciation of nature and our exact place within the cosmos than academic scientific knowledge, science and travel writer Jamie Carter takes the reader on a 12 month tour of the night sky's incredible annual rhythms that say so much about Earth. During the journey he learns about the celestial mechanics at work in the skies above that are - to the beginner - almost beyond belief. As well as the vital constellations and clusters, and the weird and wonderful nebulas, he searches out "dark sky destinations" across the globe that help increase knowledge and give a new perspective on familiar night sky sights. On the journey he witnesses a solar eclipse and grapples with star-charts, binoculars, smartphone apps, telescopes, spots satellites and attempts basic astro-photography. By year's end, the reader will be able to glance at the night sky from anywhere on the planet and tell what direction he or she is facing, what time it is, where all the planets are and even where the Galactic Center Point is.

This is a book on planets: Solar system planets and dwarf planets. And planets outside our solar system - exoplanets. How did they form? What types of planets are there and what do they have in common? How do they differ? What do we know about their atmospheres - if they have one? What are the conditions for life and on which planets may they be met? And what's the origin of life on Earth and how did it form? You will understand how rare the solar system, the Earth and hence life is. This is also a book on stars. The first and second generation of stars in the Universe. But in particular also on the link between planets and stars - brown dwarfs. Their atmospheric properties and similarities with giant exoplanets. All these fascinating questions will be answered in a non-technical manner. But those of you who want to know a bit more may look up the relevant mathematical relationships in appendices.

This book is an amateur astronomer's guide to the mythology and symbolism associated with the celestial bodies in the Solar System, and even includes some of the legendary tales of people who had or have a connection with these objects. It explores different cultures (for example, the Greco-Roman and the Norse) and different times and how stories were used to explain the worlds they saw above them. You'd be amazed how much of our world today reflects the myths and stories of these cultures! Most amateur astronomers are familiar with the various Solar System objects, but they will be only peripherally aware of what ancient cultures thought of these other worlds. In fact, the mythology of the planets challenges many twenty-first century concepts and beliefs There are other books available on astromythology, but this one focuses mostly on our own Solar System, as opposed to the constellations and deep sky objects. Alexander offers a new angle on timeless subjects and is exciting, informative and dramatic, as well as surprisingly relevant to everyday life. Find out for yourself how our modern world is steeped in the bygone worlds of yesteryear.

You too can follow in the steps of the great astronomers such as Hipparchus, Galileo, Kepler and Hubble, who all contributed so much to our modern understanding of the cosmos. This book gives the student or amateur astronomer the following tools to replicate some of these seminal observations from their own homes: With your own eyes: Use your own observations and measurements to discover and confirm the phenomena of the seasons, the analemma and the equation of time, the logic behind celestial coordinates, and even the precession of the equinoxes. With a consumer-grade digital camera: Record the changing brightness of an eclipsing binary star and show that a pulsating star changes color as it brightens and dims. Add an inexpensive diffraction grating to your camera and see the variety of spectral features in the stars, and demonstrate that the Sun's spectrum is similar to one particular type of stellar spectrum. With a backyard telescope: Add a CCD imager and you can measure the scale of the Solar System and the distance to a nearby star. You could even measure the distance to another galaxy and observe the cosmological redshift of the expanding universe. Astronomical Discoveries You Can Make, Too! doesn't just tell you about the development of astronomy; it shows you how to discover for yourself the essential features of the universe.

This is the unique story of observing a total solar eclipse for no less than 74 consecutive minutes. On the summer morning of June 30, 1973, the Sun rises on the Canary Islands. But it is strangely indented by the Moon. The eclipse of the century has just begun. From the west, the lunar shadow rushes to the African coast at a velocity of over 2000 kilometers per hour. Astronomers on the ground will enjoy seven short minutes of total eclipse to study the solar corona - too short for Pierre Lena and seven scientists who board the Concorde 001 prototype, an extraordinary plane to become the first commercial supersonic aircraft. With Andre Turcat as chief pilot and a crew of five, at 17000 m altitude, the aircraft remains in the lunar shadow for 74 minutes, a record time of scientific observations not yet beaten and allowing for exceptional measurements. Science, technology, aviation and history combine in the story of a unique human adventure aboard a legendary aircraft, illustrated with a rich and original iconography. It reflects the wonderful domains that science and technology can open, and the passion in the professions they offer. A must read for every eclipse chaser and fan of true scientific adventures.On the summer morning of June 30, 1973, the Sun rises on the Canary Islands. But it is strangely indented by the Moon.

"The bubbles were swirling all around me, massaging my body. As I luxuriated in this fantastic bath, .... I gasped as I realized that these were miniature galaxies bringing the whole Cosmos into my bathtub..."

Alfie is back. And so are George and other characters of the author s previous book "Einstein s Enigma or Black Holes in My Bubble Bath." The present book, "Universe Unveiled - The Cosmos in My Bubble," can be considered a sequel to the previous one. It is nontechnical and descriptive. The scientific content is presented through the discussions between Alfie, the enlightened learner and George, professor of astrophysics. Fantasies, based on these discussions that cover scientific facts, are created by the magical bubble baths taken by Alfie.

The cosmic journey begins with ancient astronomers, such as Aristarchus and Ptolemy of Greece, Aryabhata from India, and Omar Khayyam from Persia.

The foundations of the cosmos, essentially the solar system, are laid by the great scientists like Copernicus, Tycho Brahe, Kepler, Galileo, and finally Isaac Newton.

This is followed by the realm of the stars with a description of stellar evolution and its three end-products, namely the white dwarfs, neutron stars, and black holes. The final phase of the cosmic journey begins with the large-scale structure of the Universe. From the early speculations of William Herschel, we move on to Harlow Shapley, the measurer of the Milky Way. The awesome vastness of the Universe is revealed by the remarkable observations of Edwin Hubble, while the strangest cosmic phenomenon of universal expansion is discovered by Hubble and his collaborator Milton Humason, the erstwhile mule driver. The theoretical basis of modern cosmology, the space-time picture of the general theory of relativity, is elucidated by Albert Einstein himself. The final chapters deal with the most modern developments such as the exact determination of the age of the Universe, dark matter, the acceleration of the universal expansion and dark energy.

"Universe Unveiled "blends accurate science with philosophy, drama, humour and fantasy to create an exciting cosmic journey that reads like a novel and educates as it entertains."

Viewing and Imaging the Solar System: A Guide for Amateur Astronomers is for those who want to develop their ability to observe and image Solar System objects, including the planets and moons, the Sun, and comets and asteroids. They might be beginners, or they may have already owned and used an astronomical telescope for a year or more. Newcomers are almost always wowed by sights such as the rings of Saturn and the moons of Jupiter, but have little idea how to find these objects for themselves (with the obvious exceptions of the Sun and Moon). They also need guidance about what equipment, besides a telescope, they will need. This book is written by an expert on the Solar System, who has had a lot of experience with outreach programs, which teach others how to make the most of relatively simple and low-cost equipment. That does not mean that this book is not for serious amateurs. On the contrary, it is designed to show amateur astronomers, in a relatively light-hearted-and math-free way-how to become serious.

Here are clear explanations of how to make superb astronomical deep-sky images using only a DSLR or webcam and an astronomical telescope - no expensive dedicated CCD cameras needed! The book is written for amateur astronomers interested in budget astrophotography - the deep sky, not just the Moon and planets - and for those who want to improve their imaging skills using DSLR and webcams. It is even possible to use existing (non-specialist astronomical) equipment for scientific applications such as high resolution planetary and lunar photography, astrometry, photometry, and spectroscopy. The introduction of the CCD revolutionized astrophotography. The availability of this technology to the amateur astronomy community has allowed advanced science and imaging techniques to become available to almost anyone willing to take the time to learn a few, simple techniques. Specialized cooled-chip CCD imagers are capable of superb results in the right hands - but they are all very expensive. If budget is important, the reader is advised on using a standard camera instead. Jensen provides techniques useful in acquiring beautiful high-quality images and high level scientific data in one accessible and easy-to-read book. It introduces techniques that will allow the reader to use more economical DSLR cameras - that are of course also used for day-to-day photography - to produce images and data of high quality, without a large cash investment.

This richly illustrated book is unique in bringing Einstein's relativity to a higher level for the non-specialist than has ever been attempted before, using nothing more than grade-school algebra. Bondi's approach with spacetime diagrams is simplified and expanded, clarifying the famous asymmetric aging-of-twins paradox. Einstein's theory of gravity, general relativity, is simplified for the reader using spacetime diagrams. The theory is applied to important topics in physics such as gravitational waves, gravitational collapse and black holes, time machines, the relationship to the quantum world, galactic motions and cosmology.

In the last thirty years humans have probed the Universe, explored the Solar System and visited with spacecraft some of the most incredible places humans have ever laid eyes upon. We have expanded our knowledge slowly and surely, but still now only see a glimpse of the bigger picture. The Cosmic Keyhole explores the big discoveries of recent years and asks what's next? How prolific is life in the Universe? How far back to the Big Bang can we probe? And what hidden treasures still await us in the hidden corners of our Solar System?
