NASA Astronaut Photographs Giant Patch of Moon-like Anorthosite Rock on Earth in Madagascar

An astronaut aboard the International Space Station captured an image of a remarkable geological formation in Madagascar, which strikingly resembles the bright highlands of the Moon. This formation is composed of anorthosite, a rock type abundant on the lunar surface, and dates back at least 600 million years, showing evidence of ancient continental collisions. Studying these terrestrial anorthosite deposits can help scientists interpret the much older lunar material.
