A 3D Habitability Map of Nearby Exoplanets Guides Future Life-Detection Missions

To the point

Led by Lisa Kaltenegger, the team used Gaia data and the NASA Exoplanet Archive to sift through more than 6,000 exoplanets and identify about 45 rocky worlds in the habitable zone and 24 in a stricter 3D habitability band as prime targets for detecting liquid water and life, naming nearby planets such as Proxima Centauri b and TRAPPIST-1 d–f–g, examining inner and outer edge orbits and eccentric ones to see how much heat a world can tolerate, and aiming to guide future observatories like JWST, the Nancy Grace Roman Space Telescope, the Extremely Large Telescope, the Habitable Worlds Observatory, and LIFE, with Gillis Lowry, Lucas Lawrence, and Abigail Bohl noting that the list helps people search more efficiently and uses Earth as the reference for habitable limits and orbital dynamics.
