Gegenschein

Gegenschein

It is a German word that serves to indicate a faint visible glow in the night sky in the opposite part to that in which the Sun is located and along the ecliptic line.

Similarly to the Zodiacal light, it is considered that this phenomenon is due to the diffusion of sunlight by grains of dust that tend to become denser in the plane of the Earth's orbit.

The gegenschein was first observed and so named by the Danish astronomer Theodor Brorsen in 1854.
