Eclipsing binaries are pairs of stars that orbit each other in such a way that, from our viewpoint on Earth, one star periodically passes in front of the other. This alignment causes the brightness of the system to dim temporarily, creating a characteristic light curve. By studying these changes in brightness, astronomers can learn about the stars' sizes, masses, and distances. These systems are important for understanding stellar evolution and the dynamics of star systems. Famous examples of eclipsing binaries include Algol and Beta Persei. Observing these stars helps scientists gather valuable data about the universe and the life cycles of stars.
