Interplanetary Dust: Comets, Meteors, Zodiacal Light, NLCís, IDPís
Dust particles ranging from the size of microns to millimeters form the smallest and most ubiquitous fraction of solid particles in our solar system. They are small, but nevertheless there are several ways in which they are visible on a dark starry night - and mostly just by the unaided eye!
Many amateur astronomers, and interested laypersons, will be familiar with the two most ubiquitous appearance forms of interplanetary dust: meteors ("shooting stars"), and comets. But how many of you know, or have seen yourself, the Zodiacal Light or Noctilucent Clouds?
Below are two of four visible phenomenon associated with interplanetary dust - zodiacal light, and Noctilucent Clouds (NLCís) - that are visible without the need for expensive equipment.Click the pictures to get more information and a larger format picture.

Note: only the zodiacal light & noctilucent cloud pages are still available. The comet & meteor pages have been discontinued. For these phenomena, see my comet & meteor picture gallery, and for backrounds on meteors & associated phenomena: www.dmsweb.org.
Dust visible in interplanetary space is visible.
Drifting clouds of dust, coated with ice, high in the atmosphere cause ghostly nighttime illuminating cloud phenomenon during summer at higher latitudes.
