Finding new worlds with a play of light and shadow

© Afrim Constantin –

Astronomers have used many different methods to discover planets beyond the solar system, but the most successful by far is transit photometry, which measures changes in a star’s brightness caused by a mini-eclipse. When a planet crosses in front of its star along our line of sight, it blocks some of the star’s light. If
