Notable Progress In Understanding The Evolution Of The Terrestrial Planets
An SwRI-led team compared the early impact history of Venus and Earth, determining that Venus experienced higher-energy impacts that created a superheated core. Models show these conditions could create Venus’ […]

Abiotic Ozone In The Observable Atmospheres Of Venus And Venus-like Exoplanets
Ozone is a potential biosignature and disambuguator between Earth-like and Venus-like exoplanets due to its association on Earth with photosynthetically produced oxygen (O2).
