Night

Night or nighttime is the period of time between the sunset and the sunrise when the Sun is below the horizon. This occurs after dusk. The opposite of night is day (or "daytime" to distinguish it from "day" as used for a 24-hour period). The start and end points of time of a night vary based on factors such as season, latitude, longitude and timezone.

At any given time, one side of the planet Earth is bathed in light from the Sun (the daytime) and the other side of the Earth is in the shadow caused by the Earth blocking the light of the sun. This shadow is what we call the darkness of night. Natural illumination is still provided by a combination of moonlight, planetary light, starlight, diffuse zodiacal light, gegenschein, and airglow. In some circumstances, bioluminescence, aurorae and lightning can provide some illumination. The glow provided by artificial illumination is sometimes referred to as light pollution because it can interfere with observational astronomy and ecosystems.

Famous quotes containing the word night:

    How insupportable would be the days, if the night with its dews and darkness did not come to restore the drooping world. As the shades begin to gather around us, our primeval instincts are aroused, and we steal forth from our lairs, like the inhabitants of the jungle, in search of those silent and brooding thoughts which are the natural prey of the intellect.
    Henry David Thoreau (1817–1862)

    “Man’s incurable loneliness” is tolerable. But nowhere to go on a Saturday night is not.
    Mason Cooley (b. 1927)

    The town is silent. The night boils with eleven stars.
    Oh starry starry night! This is how
    I want to die.
    Anne Sexton (1928–1974)
