Pinwheels in the sky?IMAGES AT LINK

Surprisingly, comets do not always appear as sweeping brooms in the sky. When viewed at the correct angle and orientation, while the comet is outgassing appropriately, a comet can actually appear as a spiral "pinwheel." Below are some photos and a short movie of comet Hale-Bopp in 1997 when it was in spiral display.

Thanks for the images. Do you have date on the Tucson carvings? Someone suggests that these might be Cro-Magnon. While we are probably descended in a significant degree from CM, CM culture is considered to be 20 to 30,000 years old. These kind of spirals were showing up in Britain a lot later than that.
