Have you ever seen a shooting star? What you really saw was a meteor! A meteor is actually a chunk of metallic or stony matter - called a meteoroid - that enters the earth's atmosphere from outer space. A comet, on the other hand, is a lump of ice and dust that periodically comes into the center of the solar system from somewhere in its outer reaches. Learn more about meteors and comets in this lively and informative book!

The manned mission is seen as a first step towards a Mars surface exploration base-station and, later, establishing permanent settlement. The location and use of Mars’s natural resources is vital to enable cost-effective long-duration human exploration and exploitation missions as well as subsequent human colonization. Planet resources include various crust-lodged materials, a low-pressure natural atmosphere, assorted forms of utilizable energy, lower gravity than Earth’s, and ground placement advantages relative to human operability and living standards. Power resources may include using solar and wind energy, importation of nuclear reactors and the harvesting of geothermal potential. In fact, a new branch of human civilization could be established permanently on Mars in the next century. But, meantime, an inventory and proper social assessment of Mars’s prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Mars with energy and other vital resources. The book collects together recent proposals and innovative options and solutions. It is a useful source of condensed information for specialists involved in current and impending Mars-related activities and a good starting point for young researchers.

Многие астрономы-профессионалы наших дней в детстве зачитывались книгами К. Фламмариона, Б. А. Воронцова-Вельяминова и другими научно-популярными изданиями. Космические исследования принесли на страницы специальных изданий новый мир планет, разительно не похожий на прежние представления. В наземной технике, используя приборы, способные анализировать ничтожные количества вещества, ученые пытаются обнаружить следы древней жизни в метеоритах, пришедших с других небесных тел. Но в научно-популярные издания новые результаты проникают медленно. Предлагаемая книга представляет собой рассказ о последних открытиях в физике планет, иллюстрируемый большим числом фотографий, цветных иллюстраций и схем. Для широкого круга читателей, интересующихся астрономией и исследованиями планет Солнечной системы.

Dwarf planets (which were formerly called asteroids except for the planet Pluto), and the smaller Solar System bodies still called asteroids today, are making front page news, particularly those that are newly discovered and those that might present a hazard to life on Earth by impacting our planet. In this age of giant telescopes and space probes, these small Solar System bodies have advanced from being tiny points of light to bodies worthy of widespread study. This book describes the dwarf planets and asteroids themselves, their origins, orbits, and composition, and at how amateur astronomers can play a part in their detection, tracking, and imaging. The book is divided into two parts. Part I describes physical properties (including taxonomic types) of dwarf planets and asteroids, how they formed in the early life of the Solar System, and how they evolved to their present positions, groups, and families. It also covers the properties used to define these small Solar System bodies: magnitude, rotation rates (described by their light-curves), and orbital characteristics. Part II opens with a description of the hardware and software an amateur or practical astronomer needs to observe and also to image asteroids. Then numerous observing techniques are covered in depth. Finally, there are lists of relevant amateur and professional organizations and how to submit your own observations to them.

This book is meant for observers who see a deep-sky object – either by star-hopping or by using a Go-To telescope – but do not observe it in detail because they don't know what to look for. It provides photographic images of all the objects discussed... not just images, but images that look exactly like the visual view through the eyepiece of telescopes of various apertures. Visually, deep-sky objects almost always look quite unlike the usual CCD images published in astronomical guides. The human eye doesn't see color at such low light levels, and the contrast of extended objects (such as nebulae and galaxies) is completely different. The author lives in a less-than ideal location for visual observing, with the city of London only about twenty miles to the south. He uses this to advantage, and amateur astronomers will find this book invaluable because it shows them what they will actually see from a typical suburban location, not a rare view under perfect skies.

12 апреля 1961 года мощная ракета-носитель вывела на орбиту космический корабль «Восток» с первым космонавтом Земли, гражданином Советского Союза, коммунистом Юрием Гагариным. За короткий исторический срок, отделяющий нас от этого выдающегося события, советская космонавтика прошла славный путь. Последовательно и успешно выполняется космическая программа нашей страны. О советской космонавтике рассказывает этот альбом, в создании которого приняли участие выдающиеся ученые, летчики-космонавты, инженеры, журналисты. В альбоме использованы фотоматериалы Центра подготовки космонавтов им. Ю. А. Гагарина, ТАСС, Совета «Интеркосмос», Госцентра «Природа», личных архивов летчиков-космонавтов СССР, фотокорреспондентов О. Кузьмина, А. Моклецова, В. Мусаэлянца, А. Пушкарева, А. Сенцова, а также фотографии И. Борисенко, Л. Десинова, Л. Путятина, А. Фесенко, Г. Щербакова.]

Amateur astronomers – particularly deep-sky observers – are always on the lookout for new observing challenges. The Herschel Objects, and How to Observe Them offers the exciting opportunity of retracing the steps of the greatest visual observer and celestial explorer that ever lived. This is a practical guide to seeing the most impressive of Herschel’s star clusters, nebulae and galaxies. There has never been – and as of the time of submitting this proposal there still isn’t – an observer’s book devoted to the Herschel objects. The US-based Astronomical League has for several years sponsored a "Herschel Club", reflecting the interest amateur astronomers have in this important but less widely known listing. The Herschel Objects, and How to Observe Them covers more than 600 of the brightest of the objects that Herschel saw, with detailed descriptions and images of 150 to 200 of the very best for viewing with amateur telescopes.

The discovery of extrasolar planets over the past decade has had major impacts on our understanding of the formation and dynamical evolution of planetary systems. There are features and characteristics unseen in our solar system and unexplainable by the current theories of planet formation and dynamics. Among these new surprises is the discovery of planets in binary and multiple-star systems. The discovery of such "binary-planetary" systems has confronted astrodynamicists with many new challenges, and has led them to re-examine the theories of planet formation and dynamics. Among these challenges are: How are planets formed in binary star systems? What would be the notion of habitability in such systems? Under what conditions can binary star systems have habitable planets? How will volatiles necessary for life appear on such planets? This volume seeks to gather the current research in the area of planets in binary and multistar systems and to familiarize readers with its associated theoretical and observational challenges.
