Zodiacal Light is a celestial phenomenon that occurs when the sun, moon, and planets align in the night sky. It is a faint, diffuse light that appears in the form of a cone or pyramid in the western sky after sunset or in the eastern sky
The zodiacal light is a faint glow of diffuse sunlight scattered by interplanetary dust. Brighter around the Sun, it appears in a particularly dark night sky to extend from the Sun's direction in a roughly triangular shape along the zodiac, and appears with less intensity and visibility along the whole ecliptic as the zodiacal band. Zodiacal light spans the entire sky and contributes to the natural light of a clear and moonless night sky. A related phenomenon is gegenschein, sunlight backscattered from the interplanetary dust, which appears directly opposite to the Sun as a faint but slightly brighter oval glow.
