Exoplanet Differential Observation

Exoplanet Differential Observation is a technique used astronomers to detect and study planets outside our solar system by comparing light measurements of a star over time. When an exoplanet passes in front of its star, it causes a slight dimming, which can be measured precisely. By observing multiple stars and comparing their light patterns, scientists can identify these small changes and determine the presence of exoplanets. This method helps distinguish between actual planetary signals and other stellar activity, allowing for accurate detection and characterization of distant worlds.
