This the Genesis Rock, a lunar rock collected during the Apollo 15 mission. Scientists announced that traces of water have been detected within the sample. The presence of water in such an old rock contradicts long held theories of the Moon's formation - that it formed in a giant collision between Earth and a Mars sized object. A Moon formed in such a way would have been mostly molten during its early life, and liquid water would have been impossible.
Ever wondered how the moon affects the tides of water on Earth? Long story short, it’s gravity. As the moon orbits the Earth, it exerts a gravitational pull on the Earth. Since the Earth is significantly larger, it doesn't actually move towards the moon, but the water on it's surface, being liquid, does move.
