About this episode

The episode explores a proposal for using a hybrid system of ground-based telescopes and a starshade to enable direct imaging of Earth-like worlds.

Could a hybrid system—30–40 meter ground-based telescopes paired with a distant 99-meter starshade—finally enable direct imaging of Earth-like worlds? We dissect a wild proposal: a sunflower-shaped starshade occluding starlight in space, diffraction control that yields a deep shadow, and the real-time adaptive optics and AI that keep ground‑based optics razor‑sharp through Earth's atmosphere. If targets out to seven parsecs can yield an hour-long spectrum, we might detect oxygen and water on ...
