Titan, the only body in the solar system aside from Earth with standing liquids on its surface, has high-latitude hydrocarbon lakes and seas. As Titan’s atmosphere generates light winds, there […]
The potential of prebiotic chemistry to propagate on an exoplanet fundamentally depends on whether the atmospheric conditions can facilitate the production of prebiotic feedstock molecules.
NASA research has shown that cell-like compartments called vesicles could form naturally in the lakes of Saturn’s moon Titan.
The multi-spheric structure of the Earth forms its skeleton, and the geological molten fluids constitute its blood. Its essence is the cross-spheric migration and redistribution of volatiles (e.g., carbon, hydrogen, […]
Abiotic H2 and hydrocarbons are found in fluids discharged from ultramafic-hosted hydrothermal vents. Beneath the hydrothermal vents, abiotic H2 and hydrocarbons can be formed by serpentinization reactions and Fischer–Tropsch-type hydrocarbon-forming […]
The gas present in planet-forming disks typically exhibits strong emission features of abundant carbon and oxygen molecular carriers.
Highly unsaturated carbon chains, including polyynes, have been detected in many astronomical regions and planetary systems.
Titan’s abundant atmospheric N2 and CH4 gases are notable characteristics of the moon that may help constrain its origins and evolution. Previous work suggests that atmospheric CH4 is lost on […]
It has been proposed, and confirmed by multiple observations, that disks around low mass stars display a molecule-rich emission and carbon-rich disk chemistry as compared to their hotter, more massive […]
Earth and other rocky bodies in the inner Solar System are significantly depleted in carbon compared to the Sun and interstellar medium (ISM) dust.
