Those traveling to dark locations can be on the lookout for Zodiacal Light. As we approach the Autumnal Equinox, about one hour before sunrise you may find a bright wedge of light appearing along the zodiac constellations in the east. This phenomenon is caused by sunlight reflecting off dust in our solar system.
This image of the zodiacal lights were taken at the ESO’s La Silla Observatory in Chile in September 2009, facing west just after sunset. Image credit: ESO/Y. Beletsky
