zodiacal light

Noun

A faint, roughly triangular, whitish glow in the night sky that appears opposite the sun and extends outward from the zodiac, or ecliptic, along the plane of the solar system. It is caused by the reflection, scattering, and transmission of sunlight by interplanetary dust particles.

ریشه

The term 'zodiacal light' comes from the fact that it is seen along the zodiac – the area of the sky through which the sun, moon and planets move.
