Definition

The gegenschein or counterglow is a faint brightness enhancement in the night sky in the direction opposite to that of the Sun (i.e., in the antisolar direction; the Sun, of course, is below the horizon at this time). The gegenschein is actually a slight brightness peak in the zodiacal light and is produced by back-scattering of sunlight from interplanetary dust particles. The gegenschein is only visible under very dark sky conditions.
