Mercury Turns Out To Be a Weird Little World 90

sighted writes "The robotic spacecraft MESSENGER, now orbiting the first planet, has found new findings odd features on its surface, including unexplained, blueish 'hollows' that may be actively forming today. The findings will be published this week in Science. One scientist said, 'The conventional wisdom was that Mercury is just like the Moon. But from its vantage point in orbit, MESSENGER is showing us that Mercury is radically different from the Moon in just about every way we can measure.'" As you might expect, National Geographic has beautiful imagery to go along with the story.

    The images you're referring to are enhanced (stretched) color, not false color. According to the official release, the hollows are "very bright and have a blue color relative to other areas of Mercury." As one image caption from NASA explains, "the enhanced-color locator image emphasizes the high reflectance and relatively blue color."
