Cool Worlds

Focuses on the astronomy of exoplanets and planetary habitability together with the scientific search for extraterrestrial life and intelligence. Typical videos analyze observational results (e.g., JWST exoplanet/exomoon surveys and interstellar object studies), explore limits on where life or intelligence could exist, and evaluate technosignatures and astroengineering concepts as ways to detect or imagine alien civilizations and first‑contact scenarios.
