A Hybrid Iron/Green-Rust-Urea Model for Prebiotic Chemistry: A Synthesis of Testable Pathways for Planetary Astrobiology

by Keith Cowing

We propose a quantitative, testable framework for abiogenesis that links submarine alkaline vents, which supply H2, ΔpH, and Fe/Fe–S catalysis, to subaerial hot-spring fields that provide wet–dry concentration and UV-driven […]

Identifying Rocky Planets And Water Worlds Among Sub-Neptune-sized Exoplanets With The Habitable Worlds Observatory

by Keith Cowing

Astronomers are debating whether the plentiful “sub-Neptune” exoplanets — worlds a bit larger than Earth but smaller than Neptune — are predominantly rocky planets, water-rich “ocean worlds,” or gas-enshrouded mini-Neptunes.
