It's time to watch for zodiacal light | | Autumn is the time to look for the zodiacal light - sunlight reflecting off dust grains that move in the plane of our solar system. You'll see it in a dark sky, as an eerie light extending up from the horizon before true dawn begins. Southern Hemisphere? Look after sunset now! How to see it.
