Icy spots on moon suggest that its axis has tilted

The moon's poles have shifted over the eons, likely as a result of geological activity beneath the lunar crust, a new study suggests.
This finding — which is based on an analysis of the distribution of water ice near the lunar north and south poles — sheds light on the structure and evolution of the moon, and also provides clues about where Earth's water came from, researchers said.
