Zodiacal Light

Zodiacal Light, February 19, 2014. This may look like a photograph of the fading twilight, but it was taken more than one hundred minutes after sunset, long after the dusk had left the sky. The glow in the middle of the photo, stretching down to the horizon is zodiacal light. It is sunlight reflecting off of interplanetary dust particles located along Earth's orbital plane. This subtle glow of light is best seen in the spring and autumn of the year, on moonless nights at a location with no light pollution. In the spring the light can be seen after sunset, and in the autumn zodiacal light is seen before sunrise.
