Scientists have made a fascinating discovery about Mercury, the closest planet to the Sun. According to a recent study, the planet’s terrains, including glacier-like features, may have been carved out by salt. This finding challenges previous assumptions about the planet’s geological history. By analyzing data from NASA’s MESSENGER spacecraft, researchers identified high concentrations of chlorine, sodium, and sulfur on Mercury’s surface. The presence of these elements suggests that salt may have played a crucial role in shaping the planet’s landscape. This study provides valuable insights into the geological processes that have shaped rocky planets like Mercury.
