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 …

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 …

AcidopHiles : a not- so-basic life
… completely inhospitable to humans. Macroscopic life forms in these conditions are extremely rare. Microscopic life forms, however, thrive. They are called extremophiles. One subset of extremophile called the acidophile live in acidic environments, at time even more corrosive than battery acid. …

Modeling Non-Rotational Ocean Circulation and Heat Distribution in Icy Moons
… are considered promising environments for extraterrestrial life. Their long-term habitability depends on internal heating and efficient vertical heat transport to maintain liquid water beneath the surface. This study models vertical heat diffusion in a non-rotating ocean column to …

Planetary Science Meets Chemistry: Studying Potential Biosignature Gases in Terrestrial Exoplanet Atmospheres
… is becoming one of the crucial ways to find extraterrestrial life. Biosignature gases are gases produced by living organisms that can accumulate to detectable levels in the atmosphere. Once detected, it can be attributed to signs of life on the planet. So far, only a few molecules have been …

Embedded Computing for Wavefront Control on Future Space Telescopes
… using this technique may be the first to detect extraterrestrial life in the universe. However, the real-time execution of adaptive optics control algorithms places unprecedented demands on spaceborne processors. Previous work has determined that processing limitations can degrade the achievable …

Experimental Validation of Melt Probe Models for the Exploration of Ocean Worlds
… are strong candidates for the first discovery of extraterrestrial life. Jupiter’s moon Europa is currently believed to have at least twice as much water as Earth. A key remaining challenge is developing a probe that can traverse tens of kilometers of ice with temperatures ranging from ~100 K to …

Last Call for Life: Habitability of Terrestrial Planets Orbiting Red Giants and White Dwarfs
… To search planets in these systems for signs of life it is essential that we understand how stellar evolution influences atmospheric photochemistry along with detectable biosignatures. We use EXO-Prime, which consists of a 1D coupled climate/photochemistry and a line-by-line radiative transfer …

Computationally Efficient Optimization of Formation Flying Trajectories, with Solar Radiation Pressure, near Lagrange Points
… understanding of the universe by searching for extraterrestrial life. While indirect detection methods have identified a vast quantity of exoplanets in habitable zones, such methods are inadequate for characterizing exoplanets. In this manner, humanity’s search for other life in the universe …
