Scientist use extremely powerful telescopes and machines to measure the brightness of stars. If a planet were to pass in front of the star than the stars brightness may dip by 1/1000th of a percent. The telescopes are so powerful that they are able to measure this dip and thus allow scientist to detect exoplanets.
