Total solar eclipses can only be observed from certain locations on Earth (Credit: NASA.gov)

Total solar eclipses, during which the Sun briefly "disappears" in the daytime, occur about every 18 months. However, unlike lunar eclipses, which can be seen worldwide, the celestial phenomenon can only be observed within a narrow, approximately 100-mile-wide, path of totality. Moreover, total solar eclipses occur at a specific location, on average, about every 360 years. This means that the chance to observe one in real-time is truly rare and special.
