To find them, he measures the light from stars over time, noting that the light will decrease when an exoplanet passes in front of a star, blocking the radiated light to Earth. "The measuring of this change in light, known as the 'transit method,' allows us to detect the presence of these distant worlds and to study their properties,"…
