The purpose of the book is a dual one: to detail the nature and results of Tunguska investigations in the former USSR and present-day CIS, and to destroy two long-standing myths still held in the West. The first concerns alleged “final solutions” that have ostensibly been found in Russia or elsewhere. The second concerns the mistaken belief that there has been little or no progress in understanding the nature of the Tunguska phenomenon. All this is treated by the author in a scholarly and responsible manner. Although the book does present certain unusual findings of Russian and Ukrainian scholars, it is important to stress that this is not a sensational book; it is, rather, a serious exposition of the results of rational investigations into a difficult scientific problem. We are demonstrating the true complexity of the problem that is now entering its second century of existence. Simple meteoritic models cannot explain all the characteristics of this complicated event, and therefore certain so-called “unconventional hypotheses” about the nature of the Tunguska explosion are to be considered as well.

This popular science book shares the fascination of the Tungus Event, a major mystery of the 20th century, in a factual and informed way. It provides "on-the-ground" descriptions of the site and explains the findings and the puzzlement of international scientists who have investigated it over the decades. After a brief and readable overview of comets, meteors, the sun and the solar system, the author ponders the range of possible explanations for the "great Siberian meteorite." The research is up to date, factual and scientific. While making no absurd claims to solving the puzzle, the author studies some intriguing clues in NASA's orbit diagrams for Comet Encke, and he is bold in discussing the possible causes of what was the greatest natural explosion in recorded history. As he points out, [Hypotheses] include rogue asteroids, mini black holes and even alien intervention....These explanations are not entirely equal to the facts. In the unique case of the Tunguska event, there was wholesale destruction to the mighty taiga woodlands but none of the debris that one would expect should exist from the body itself. Evidence like a strewn field of meteorite debris or meteoric dust on the trees and ground were never found, nor were any craters, in the area beneath the site of the fireball nor anywhere along the path it took. There are no craters because the Tunguska Cosmic Body (TCB) did not hit the ground. Atmospheric anomalies prior to the dramatic appearance of the fiery body puzzlingly occurred for several days, adding to the enigma. There are just a handful of English-language books on this subject. The most recent, The Tunguska Mystery, by the Russian Rubstov (Astronomers Universe, Springer Science 2009) is authoritative but highly technical and hard going for the general reader. Mr. Engledew instead tells the story in a balanced and engaging style.

Genesis Im Anfang w ar Leere: „Finsternis lag über der Ur ut“. Dann kam es zu einem gewaltigen Energieausbruch: „Es werde Licht. Und es wurde Licht.“ Woher diese Energie kam, weiß ich nicht. Bekannt ist jedoc h, was anschließend geschah: Die Energie kondensierte zu Materie und ihrem geheimn- vollen Spiegelbild – der Antimaterie – in vollkommen gl- chen Mengen. Gewöhnliche Materie ist uns vertraut; aus ihr bestehen Luft und Erde und die Lebewesen. Doch ihr getreues, in allen Erscheinungen identisches Spiegelbild, das erst im Inneren der Atome seine „verkehrte“ Natur offenbart, ist uns mehr als fremd. Es ist die Antimaterie, die Antithese zur Materie. Antimaterie gibt es heute nicht in größeren Mengen, zumindest nicht auf der Erde. Der Grund für ihr V- schwinden gehört zu den unerklärten Geheimnissen des Universums. Wir wissen aber, dass Antimaterie existiert, denn sie konnte in physikalischen Experimenten in win- gen Mengen hergestellt werden. Antimaterie zerstört jede gewöhnliche Materie, mit der sie in Berührung kommt, in einem grellen Blitz. Die seit XII Vorwort Milliarden von Jahren gebündelte Energie der Materie wird in einem solchen Augenblick explosionsartig frei- setzt. Antimaterie könnte die ideale Energiequelle werden, die Technologie des 21. Jahrhunderts. Doch ihre Fähigkeit zur absoluten Zerstörung könnte sie auch zu einer ulti- tiven Massenvernichtungswaffe machen.

This streamlined text (21 chapters) provides clarity with coverage of such topics as planetary origins, star formation, the formation and evolution of galaxies, and cosmology. The text introduces and reinforces the concept that stellar and interstellar research have much in common with planetary science and that both are closely related to the formation and evolution of the universe as a whole. Chapter 12 bridges the sections on planets and stars by reviewing the origins of both. The text also contains many features to help students appreciate Earth's role in the universe, including Science and Society boxes that cover the effects of technology on the Earth's atmosphere. Plus, Astronomical Activities and WWW Activities are at the end of each chapter. Voyage Through the Solar System CD-ROM and The SkyÖ Student Edition CD-ROM are included with each new student copy of the text.
