Fall is officially here and with that a good time to see the zodiacal light, and with the Moon absence from the morning sky for the next couple weeks it makes a particularly good time to get a glimpse.
What is zodiacal light and what causes it? It is a pyramid-shaped glow that appears in the eastern sky before dawn or western sky just after sunset. This phenomenon is caused by sunlight reflecting off the dust particles that move in the same plane as the Earth and other planets as they orbit the Sun. The zodiacal light appears brighter the closer you get to the equator.
At this time of year you can see the zodiacal light an hour or two before dawn in the eastern sky. Observers in the Southern Hemisphere can see it after sunset. Dark skies will be needed to see it, so try to get far away from the city lights.
