What is twilight?

Twilight

Twilight is the time between dawn and sunrise or between sunset and dusk, during which sunlight scattering in the upper atmosphere illuminates the lower atmosphere, and the surface of the earth is neither completely lit nor completely dark. The sun itself is not directly visible because it is below the horizon. Owing to the distinctive quality of the ambient light at this time, twilight has long been popular with photographers, who refer to it as Sweet Light, and painters, who refer to it as the "blue hour", after the French expression l'heure bleue.

Famous quotes containing the word twilight:

    You cannot, in human experience, rush into the light. You have to go through the twilight into the broadening day before the noon comes and the full sun is upon the landscape.
    Woodrow Wilson (1856–1924)

    But we still remember ... above all, the cool, free aspect of the wild apple trees, generously proffering their fruit to us, though still green and crude,—the hard, round, glossy fruit, which, if not ripe, still was not poison, but New English too, brought hither, its ancestors, by ours once. These gentler trees imparted a half-civilized and twilight aspect to the otherwise barbarian land.
    Henry David Thoreau (1817–1862)

    I rejoice that there are owls.... They represent the stark twilight and unsatisfied thoughts which all have.
    Henry David Thoreau (1817–1862)
