One of the most surprising discoveries of the NASA’s Messenger mission was the presence of unusual, bright, irregular and rimless flat-floored depressions on the surface of Mercury. These depressions, called hollows, are usually found on crater walls, rims, floors and central peaks. Since the hollows appear fresh, they may be actively forming today through a mechanism that could involve the loss of volatile compounds, but understanding how the hollows formed is still a major challenge for scientists.
