В книге рассказано об одном из интереснейших явлений природы — полярных сияниях. Автор рассматривает причины их возникновения, связь с солнечной активностью, ближним и дальним космосом, влияние полярных сияний на жизнь и деятельность людей в высоких широтах. Использованы результаты исследований, проведенных в последнее время с помощью геофизических ракет и искусственных спутников Земли. Для широкого круга читателей, интересующихся необычными явлениями природы.

This book introduces the reader to the field of nuclear astrophysics, i.e. the acquisition and reading of measurements on unstable isotopes in different parts of the universe. The authors explain the role of radioactivities in astrophysics, discuss specific sources of cosmic isotopes and in which special regions they can be observed. More specifically, the authors address stars of different types, stellar explosions which terminate stellar evolutions, and other explosions triggered by mass transfers and instabilities in binary stars. They also address nuclear reactions and transport processes in interstellar space, in the contexts of cosmic rays and of chemical evolution. A special chapter is dedicated to the solar system which even provides material samples. The book also contains a description of key tools which astrophysicists employ in those particular studies and a glossary of key terms in astronomy with radioactivities.

Star clusters are some of the most beautiful objects in the night sky and are prime targets for observational astronomers as well as astrophotographers. Using some of the newer technologies and larger and more powerful telescopes available today to amateur astronomers, many more of these dazzling groupings of stars can now be located and viewed throughout the year. In this field guide that will help you to decide what to look for and where to look for it, as well as what equipment to use, you will find what you need, whether you are a beginner in the field or an experienced observer. So on the next clear night, take your book and your binoculars or telescope and maybe your camera outside and see what new wonders can be revealed to you. You won’t be disappointed!

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.
