On Earth, dust particles are viewed mainly in terms of their physical effects, like erosion. But, in exotic locales from Mars to Venus to Jupiter s icy moon Europa, electrical effects can affect the chemical composition of a planetary body s surface and atmosphere in a relatively short time, according to new research from Washington University in St. Louis. This direction of scientific investigation has been largely overlooked in the past, said Alian Wang, research professor in the Department of Earth and Planetary Sciences in Arts & Sciences. Researchers are used to thinking inside the box based on terrestrial experience.
