Twilight is not simply the abrupt shift from darkness to light, but rather a gradual transition governed by the Earth's rotation and the position of the sun. As the sun dips below the horizon, its rays continue to illuminate the atmosphere, scattering light and creating a range of colors. This phenomenon, known as atmospheric refraction, is responsible for the vibrant hues of twilight. The duration of twilight varies depending on the time of year and the observer's latitude. During the summer solstice, twilight can last for several hours, while during the winter solstice, it may be fleeting.
