...can sometimes be seen illuminated in the pre-dawn sky as a faint cone called the Zodiacal Light, or False Dawn. It is most easily seen near Autumnal Equinox (September 22nd) in the Northern Hemisphere, but because of moonlight this year, this week will be the best time to look for it.
(Shown about two hours before sunrise for mid-Northern latitudes. The Milky way is also visible in the right half of the image.)
