Exomorphic Catalysis: A Discipline Dedicated to Energetic Disequilibria and the Activation of Life-Potential in Non-Terrestrial Environments
The search for life beyond Earth has long been guided by two dominant paradigms: astrobiology, which seeks environments capable of supporting life as we know it, and planetary engineering, which […]

New Constraint On Europa’s Ice Shell: Magnetic Signature From The Ocean
Jupiter’s icy moons are believed to host subsurface liquid oceans, and among them, Europa stands out as one of the most promising candidates for extraterrestrial life.

Callisto Is Very Likely an Ocean World
More pocked with craters than any other object in our solar system, Jupiter’s outermost and second-biggest Galilean moon, Callisto, appears geologically unremarkable. In the 1990s, however, NASA’s Galileo spacecraft captured […]
