Zodiacal Light

The zodiacal light is a weak band of light, almost triangular in shape, which can be seen in the night sky extending along the plane of the ecliptic where the constellations of the Zodiac are found. It covers the sky completely although it is only visible above the plane of the ecliptic and is responsible for 60% of the natural light on a moonless night. It is caused by the scattering of sunlight on dust particles found throughout the solar system.
