 Pillars are caused by ice crystals floating in high clouds. When a bright light shines through such a cloud, the flat surfaces of plate-shaped crystals reflect the light up and down to form luminous columns. Usually the bright light is the sun or Moon; in this case it was Venus and Jupiter. a nice shot from space weather spaceweather.com/besides solar cycles did the Mayans or other humans study the solar system an planetary aliments ?
