Structure and Reactivity of Terrestrial and Extraterrestrial Pyrrhotite
… in terrestrial rocks, ore deposits, and many extraterrestrial materials. The non-stoichiometry due to metal vacancies relates to a variety of composition-dependent crystallographic superstructures, but little of the existing structural and microstructural complexity has been explored yet. This …

The Divine Pedagogy: Theological Explorations of Intelligent Extraterrestrial Life
… related subject of the existence of intelligent extraterrestrials has remained an important question for Christian theology from antiquity until the modern age. Advancements in space science of the twentieth and twenty-first centuries have revealed a vast universe containing trillions of …

An electrodynamic balance (EDB) for extraterrestrial cloud formation studies
Ice clouds scatter and absorb solar radiation, affecting atmospheric and surface temperatures (Gettelman et al., 2012). On Mars, where ice contained in clouds makes up a large portion of total atmospheric water vapor, ice clouds also alter the planetary water budget (Maltagliati et al., 2011; …

Electrohydrodynamic enhancement of extraterrestrial capilliary pumped loops for nuclear applications
… of capillary pump loops (CPL) for use in extraterrestrial nuclear applications. A capillary pump uses capillary action through a porous wick to transport heat and mass. The capillary pump is being considered as a method to improve heat transport in extraterrestrial nuclear applications. …

Technologies of perception : searches for life and intelligence beyond Earth
… technological capabilities to test for signs of extraterrestrial life. While exobiologists developed visual techniques to detect whether sites beyond Earth might harbor microbes, "biosignatures," radio astronomers searched for extraterrestrial intelligence (SETI) in the form of …

Geochemical evaluation of the Younger Dryas Boundary (YDB) impact hypothesis, El Carrizal Baja California Sur, Mexico
The Younger Dryas Boundary (YDB) extraterrestrial impact hypothesis is purported to have triggered the Younger Dryas stadial and coincides with the Pleistocene extinction and disappearance of the Clovis Paleo-Indian culture. Evidence supporting or refuting this hypothesis has great implications for …
