Zodiacal Light: A Ghostly Glow Along the Horizon

Zodiacal light is a faint, triangular glow visible before dawn or after dusk.
It stretches along the zodiac, the path the Sun, Moon, and planets follow.
The glow comes from sunlight scattering off interplanetary dust.
This dust originates from comets and asteroid collisions.
Zodiacal light is best seen in very dark skies, far from city lights.
In the Northern Hemisphere, it’s easiest to spot in spring evenings and autumn mornings.
The phenomenon can extend high above the horizon, resembling a false dawn.
Space missions like Juno and Helios have studied the dust cloud that causes it.
Medieval observers sometimes mistook it for atmospheric twilight.
Zodiacal light is one of the most delicate and mysterious spectacles of the night sky.
