In 1908, thunderous blasts and blazing fires from the sky descended upon the desolate Tunguska territory of Siberia. The explosion knocked down an area of forest larger than London and was powerful enough to obliterate Manhattan. The mysterious nature of the event has prompted a wide array of speculation and investigation, including from those who suspected that aliens from outer space had been involved. In this deeply researched account of the Tunguska explosion and its legacy in Russian society, culture, and the environment, Andy Bruno recounts the intriguing history of the disaster and researchers' attempts to understand it. Taking readers inside the numerous expeditions and investigations that have long occupied scientists, he foregrounds the significance of mystery in environmental history. His engaging and accessible account shows how the explosion has shaped the treatment of the landscape, how uncertainty allowed unusual ideas to enter scientific conversations, and how cosmic disasters have influenced the past and might affect the future.

Au cours de son histoire, la science a livré de nombreux combats. À la Renaissance, Galilée a été condamné par le tribunal de l'Inquisition. Depuis lors, le Vatican a fait amende honorable, mais il est des idéologies plus profondément ancrées qui refusent de s'incliner devant les arguments scientifiques. Tel le racisme, qui a fait tant de mal au genre humain mais qui continue pourtant d'empoisonner nos sociétés. Quant au spécimen qui imprégnait le 19e siècle, il a subi un coup dur lorsque Darwin a publié L'Origine des espèces. Au grand dam des créationnistes, l'homme cessait alors de se considérer comme un être à part, directement issu de la volonté divine. Quant aux extraterrestres, suspectés un temps d'avoir capturé des terriens à bord de leurs ovnis ou participé à l'érection des pyramides, la science les a également remis à leur place.
