When a planet crosses directly between us and its star, we see the star dim slightly because the planet is blocking out a portion of the light. Measuring these dips in starlight is one technique, which is known as the “transit method,” that scientists use to identify exoplanets. (NASA’s Goddard Space Flight Center)
