45 Rocky Exoplanets in Habitable Zones: Guiding Biosignature Searches and JWST Observations
To the point
Led by Lisa Kaltenegger and using Gaia and NASA Exoplanet Archive data, scientists narrowed thousands of exoplanets to about 45 rocky worlds in their stars’ habitable zones where liquid water might exist, ranking the best targets for future telescopes to search for signs of life and testing how factors like orbital shape and Earth’s own environment affect habitability, with notable candidates including TRAPPIST-1, LHS 1140 b, and Proxima Centauri b.
