"Detecting Alien Life: Using Carbon Dioxide to Find Oceans on Distant Planets"

Researchers propose that the absence of carbon dioxide in a planet's atmosphere could indicate the potential for liquid water on its surface, increasing the chances of habitability. They suggest that the combination of a CO2 deficit and the presence of ozone could indicate not just microbial life forms, but potentially a planet teeming with organisms. This approach could aid in the search for habitable exoplanets and is feasible with current telescopic technology.
