Seeking another Earth? Look for low carbon dioxide What do we need to find if we want to discover another Earth? If an exoplanet is too far away for even the most powerful telescopes to search directly for water or…

New Research Suggests CO2 Levels in Planet Atmospheres Could Indicate Habitability

New research has suggested that the levels of carbon dioxide (CO2) in a planet’s atmosphere relative to its neighboring planets could indicate the presence of liquid water, potentially signifying habitability. The findings, published in the journal Nature Astronomy, offer a…
