Titan is covered by electrically charged sand grains, experiments suggest



Washington (UPI) Mar 27, 2017
New research suggests the sand grains on Titan, Saturn's largest moon, behave similar to the packing peanuts used in shipping boxes. Lab experiments suggest the granules become electrically charged and clump together, resisting motion as they attach themselves to other hydrocarbons. The sand grains become charged as they're excited by strong winds and hop along the surface - a phenomenon known as saltation. Researchers believe the electrically bound granular clumps can maintain t ... read more

During prolonged night, when the surface is lit only by blue Earthlight, temperatures dip below -170+ C. Some locations at higher latitudes have shorter nights, though others have much longer ... more
