A Breath of CO₂: Searching for Life-Friendly Planets through Atmospheric Clues

This study explores how future space missions like LIFE could detect trends in atmospheric CO₂ across many exoplanets to identify signs of habitability or life. Using simulations and statistical modeling, the authors show that CO₂ patterns influenced by geology—and potentially biology—can be detected in planet populations, though observational biases must be addressed for reliable results.
