Abiotic Ozone In The Observable Atmospheres Of Venus And Venus-like Exoplanets - Astrobiology

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). However, the existence of ozone in Venus’s observable atmosphere, a planet with no known life, raises the possibility of ozone biosignature false-positives on Venus-like exoplanets. We use a photochemical model of Venus’s […] The post Abiotic Ozone In The Observable Atmosph…
