"Exploring the Seven Most Promising Worlds for Advanced Civilizations"

A recent paper identifies seven known exoplanets that could potentially have been the starting point for intentional panspermia, the seeding of life on Earth by an advanced civilization. The study considers factors such as planet size, temperature, habitable zone placement, and age, ultimately narrowing down the candidates to seven exoplanets. Kepler-452 b, with a star and orbit similar to ours, stands out as a potentially interesting focal point for future exoplanet surveys. While speculative, the paper underscores the importance of detailed examination of known exoplanets in the search for advanced civilizations.
