What method do missions like Kepler and TESS primarily use to confirm exoplanets?
Answer
Observing dips in starlight caused by planetary transit.
The Kepler and TESS missions utilized the transit technique, which involves detecting the slight dimming of a star's light when an orbiting planet passes directly between the star and the observing telescope.
