Astronomers have identified 45 exoplanets that deserve priority attention in the search for biosignatures and signs of life beyond Earth.
A new catalog identifies 45 high-priority exoplanets for habitability research, combining data from the James Webb Space Telescope and ground-based observatories. The planets span a range of sizes, temperatures, and host star types.
The study ranks candidates using a multi-factor habitability index that accounts for stellar flux, atmospheric retention potential, and orbital stability over geological timescales.
