Transiting exoplanets refers to the study of planets outside of our solar system that pass in front of their host star as seen from Earth. This transit causes a slight decrease in the star's brightness, which can be detected by astronomers using telescopes. By analyzing the data collected during these transits, researchers can determine properties of the exoplanet such as its size, orbital period, and atmosphere. This research area has proven to be a valuable tool for discovering and characterizing exoplanets, leading to a better understanding of the diversity of planets in our galaxy.
