{"product_id":"9780875867823","title":"The Tungus Event, or The Great Siberian Meteorite","description":"\u003cp\u003eSomething  exploded above Siberia in 1908 and no one is quite sure what — or  why. What burned 830 square miles of forest and some 30 million trees on a fine summer's morning? This book combines a hard popular science approach and lively description of the \"Tungus event\", giving the reader the stories of the early expeditions, the research that has gone on over a century, and a range of possible explanations.\u003c\/p\u003e\u003cp\u003eThis popular science book examines 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. \u003c\/p\u003e\u003cp\u003eAfter 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. \u003c\/p\u003e\u003cp\u003eThere are just a handful of English-language books on this subject. The most recent, 'The Tunguska Mystery,' by the Russian Rubstov, is authoritative but highly technical and hard going for the general reader. Mr. Engledew instead tells the story in a balanced and engaging style.\u003c\/p\u003e","brand":"Algora Publishing","offers":[{"title":"Default Title","offer_id":47131222278384,"sku":"9780875867823","price":21.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780875867823_p0.jpg?v=1763833788","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780875867823","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
