Where Did Mercury’s Spots Come From?

The video explores Mercury's unique features, focusing on mysterious shiny spots on its surface. Initial observations by Mariner 10 and later detailed studies by MESSENGER revealed these spots as depressions, possibly formed by sublimating sulfur. This process might create sinkhole-like structures, explaining their youthful appearance. Despite MESSENGER's mission ending in 2015, future data from Beppy Colombo may provide further insights into these phenomena.
