Scientists have recently unveiled some of the geological mysteries of Mercury, the planet closest to the sun. After analyzing data collected by NASA’s MESSENGER spacecraft, researchers have determined that a large portion of the planet’s surface is covered in a layer of salt. This layer of salt is believed to have been created by the evaporation of a primordial ocean that once existed on Mercury’s surface. The findings provide insight into how Mercury’s surface has evolved over time, and could help scientists get a better understanding of the planet’s geological history.
