Based on the author’s own work and results obtained by international teams he coordinated, this SpringerBrief offers a concise discussion of the origin and early evolution of atmospheres of terrestrial planets during the active phase of their host stars, as well as of the environmental conditions which are necessary in order for planets like the Earth to obtain N_2-rich atmospheres. Possible thermal and non-thermal atmospheric escape processes are discussed in a comparative way between the planets in the Solar System and exoplanets. Lastly, a hypothesis for how to test and study the discussed atmosphere evolution theories using future UV transit observations of terrestrial exoplanets within the orbits of dwarf stars is presented.

Exploring the science of planetary atmospheres, this book delves into the physical and chemical processes that shape the atmospheres of various celestial bodies. It covers topics such as atmospheric composition, dynamics, and the interaction between solar radiation and planetary surfaces. The text emphasizes the importance of understanding these processes for insights into climate, habitability, and the evolution of planets. With a blend of theoretical frameworks and practical applications, it serves as a comprehensive resource for researchers and students in planetary science and related fields.

In this book an international group of specialists discusses studies of exoplanets subjected to extreme stellar radiation and plasma conditions. It is shown that such studies will help us to understand how terrestrial planets and their atmospheres, including the early Venus, Earth and Mars, evolved during the host star’s active early phase. The book presents an analysis of findings from Hubble Space Telescope observations of transiting exoplanets, as well as applications of advanced numerical models for characterizing the upper atmosphere structure and stellar environments of exoplanets. The authors also address detections of atoms and molecules in the atmosphere of “hot Jupiters” by NASA’s Spitzer telescope. The observational and theoretical investigations and discoveries presented are both timely and important in the context of the next generation of space telescopes. The book is divided into four main parts, grouping chapters on exoplanet host star radiation and plasma environments, exoplanet upper atmosphere and environment observations, exoplanet and stellar magnetospheres, and exoplanet observation and characterization. The book closes with an outlook on the future of this research field.

Tato kniha přináší překvapující odpovědi na mnohé vzrušující otázky, např.typu:Sloužila středověká astronomie především zájmům církve? Nepředstavuje dvanáct apoštolů rovněž dvanáct znamení zvěrokruhu? Není posvátné číslo sedm symbolem pevných vazeb mezi Sluncem, Měsícem, Merkurem, Venuší, Marsem,Jupiterem a Saturnem? Jak to, že po zničení templářského řádu nebyla postavena už žádná významná katedrála? Co znamenají tajuplné symboly na portálech křesťanských katedrál? Nejsou to kamenné horoskopy dějin lidstva? Odkud však získali jejich středověcí stavitelé příslušné vědomosti?

Die Dokumentation enthüllt die Aktivitäten einer einflussreichen militärisch-politischen Gruppe, die geheime Technologien zur Bewusstseinskontrolle und Implantate nutzt, um Informationen über UFO-Entführungen zu sammeln und genetische Experimente sowie Tests exotischer Waffen und UFO-ähnlicher Flugkörper durchzuführen.
