Moons of rogue planets can be warm and wet for billions of years. Tidal forces heat them from within, and a hydrogen atmosphere acts like a blanket. Scientists believe RNA—a key ingredient of life—could even assemble there. Darkness is no barrier to the living.
🎯 The hydrogen "fur coat" of such a moon can weigh as much as several Earth oceans, yet remain transparent—on the surface, eternal twilight, but warm.
