What would it take to find another Earth, if one even exists?
Astrophysicist and planetary scientist Sara Seager explores the search for Planet B, a true Earth-like exoplanet with continents, oceans, sunlight, and a thin atmosphere capable of supporting life. The search for Earth’s Twin helps scientists understand planetary habitability, the origins of life on Earth, and how rare Earth-like conditions may be in the universe.
Seager’s work centers on exoplanets, Earth-like planets, habitable zones, planetary atmospheres, and chemical signs of life, while also examining Venus, phosphine gas, and why finding a second Earth remains one of astronomy’s greatest challenges.
