On The Divergent Evolution Of Io And Europa As Primordial Ocean Worlds

Galilean moons exhibit a decrease in bulk density with distance from Jupiter, which may reflect differences in evolutionary paths and water loss.

Probing Thermal Gradients Of Habitable-zone Rocky Planets Using Direct Imaging As An Anti-indicator Of A Global Surface Ocean

Future direct-imaging missions, such as the Large Interferometer for Exoplanets (LIFE), aim to observe thermal emission from potentially habitable planets to characterize their surface environments and search for signs of […]

Woods Hole Oceanographic Institution Selected By NASA To Investigate Ocean Worlds And Their Organic Carbon Cycles

Ocean worlds such as Jupiter’s icy moon Europa and Saturn’s counterpart, Enceladus, could be among the most favorable places to discover life beyond Earth—and perhaps even a second, independent origin […]

Mapping Mars’ Large River Drainage Systems For The First Time

Billions of years ago, it rained on Mars. The water collected in valleys and rivers, filled and spilled over the rims of craters, and was funneled into canyons, perhaps even […]

How Did Earth’s Animal Life Transition From Aquatic To Terrestrial Environments?

The transition from aquatic to terrestrial life has been one of the most significant evolutionary challenges. This decisive process in the evolution of life on Earth required a profound renewal […]

Sample Preparation for MALDI-TOF Mass Spectrometry of Model Prebiotic Reactions in Simulated Ocean World Environments

The prebiotic potential of ocean worlds such as Europa and Enceladus, while not well constrained, is vital in the search for potential life elsewhere.

Geochemical Mobility of Elements in Antarctic Environments Affected by CO2-Rich Hydrothermal Fluids: Astrobiological Implications

Hydrothermal systems are widespread in our solar system. Identification of alteration mineral assemblages on Mars and potentially in ocean worlds such as Enceladus suggests the existence of extensive hydrothermal fluid-igneous […]
