Exoplanet Atmospheres and the Quest for Biosignatures: Results, Debates, and Future Missions
To the point
Scientists are learning to read the atmospheres of distant planets like barcodes to spot signs of life, using improvements in telescopes and methods to detect molecules such as water, methane, and carbon dioxide, while sorting out debates over faint signals and expanding the search beyond strict habitable zones with missions like Plato, Roman, Ariel, and the Habitable Worlds Observatory.
