Rich in historical context, the narrative showcases the observatory's impact on both military and civilian sectors, illustrating how its discoveries have influenced modern science.
Astronomical discovery unfolds through a multifaceted process, involving multiple stages such as research, interpretation, and comprehension. The book delves into the intricacies of how astronomical knowledge evolves over time, highlighting the challenges and breakthroughs encountered along the way.
Focusing on the fascination with extraterrestrials, this guide offers a clear and engaging exploration of the 20th-century obsession with alien life. It delves into the cultural, social, and historical contexts that fueled this intrigue, presenting a comprehensive overview that is both informative and easy to understand.
The book captures the insights and discussions from a pivotal 1981 seminar at the Smithsonian's National Air and Space Museum, where historians gathered to explore the evolution of space history. It delves into the key themes presented, the challenges faced in documenting space exploration, and the impact of these historical narratives on our understanding of space endeavors. The seminar serves as a platform for examining the intersection of history, science, and public perception regarding humanity's ventures into space.
The exploration of space and its cultural implications are central to this interdisciplinary volume by former NASA Chief Historian Steven Dick. He delves into astrobiology, cosmic evolution, and the role of astronomical institutions, while also addressing the philosophy of astronomy. The book emphasizes the profound relationship between the cosmos and human culture, echoing Carl Sagan's concept of the "cosmic connection."
Since the invention of the telescope 400 years ago, astronomers have rapidly discovered countless celestial objects. But how does one make sense of it all? Astronomer and former NASA Chief Historian Steven J. Dick brings order to this menagerie by defining 82 classes of astronomical objects, which he places in a beginner-friendly system known as "Astronomy’s Three Kingdoms.” Rather than concentrating on technicalities, this system focuses on the history of each object, the nature of its discovery, and our current knowledge about it. The ensuing book can therefore be read on at least two levels. On one level, it is an illustrated guide to various types of astronomical wonders. On another level, it is considerably more: the first comprehensive classification system to cover all celestial objects in a consistent manner. Accompanying each spread are spectacular historical and modern images. The result is a pedagogical tour-de-force, whereby readers can easily master astronomy’s three realms of planets, stars, and galaxies.
Kniha Stevena Dicka se zabývá otázkou, nakolik je život univerzální a dochází ke zjištění, že při přechodu od uzavřeného vesmíru k otevřenému universu je třeba revidovat představu, že by se projevy života, byť na té nejnižší úrovni, omezovaly pouze na naši planetu. Autor je však kritický i k současným objevům mikrofosilií na Marsu už z toho důvodu, že se kromě vědy zabývá rovněž její historií. Na příkladu kanálů na Marsu ukazuje, nakolik utvářela vědecké koncepty i tak renomovaných vědců, jako byl Flammarion či vědci „na pomezí“ jako byl Lowell, imaginace. Ta ve spojení s nedostatečným přístrojovým zázemím dala vzniknout i fantastičtějším představám, než byly dlouho kontroverzní kanály na Marsu. Přese všechnu skepsi však Dick přesvědčivě dokládá, že astronomičtí pluralisté jako byl Flammarion měli pravdu v jednom, že v éře „mnohosti světů" nemůžeme vyloučit hypotézu, že v myriádách galaxií existují podmínky umožňující život. Dick se rovněž zabývá rolí, kterou tyto představy, namnoze zlidovělé, hrají ve vědecko-fantastické literatuře a filmech. Od geoncentrismu k heliocentrismu musela vést cesta dále – k jistému panbiologismu, jehož zastáncem, se všemi skeptickými výhradami, tento biokosmolog je.
