Description
wilight is the time between darkness and sunrise in the morning, and sunset and complete darkness in the evening, when there is light outside, but the Sun is below the horizon. There are 3 types of twilight: civil, nautical, and astronomical.
Twilight occurs when the Earth's upper atmosphere scatters and reflects sunlight and illuminates the lower atmosphere.
Astronomers define twilight in the context of the Sun's elevation with respect to the horizon (the angle that the geometric center of the Sun makes with the horizon). They also distinguish between 3 types of twilight, dawn and dusk based on this definition.
