Gegenschein

The gegenschein is a faint spot of light in the sky, diametrically opposite of the Sun.

The fact that its spectrum is identical to that of the Sun, like the zodiacal light, enforces the conclusion that we are seeing sunlight reflected from dust grains in the plane of the solar system.

There have been reports that under very favorable viewing conditions the zodiacal light extends to the gegenschein. The gegenshein is even fainter than the zodiacal light — fainter than the Milky Way — so any additional light from Moon, street lights, or a nearby planet and any obscuring haze make it impossible to see this faint glow.
