The Moon shines over the entire Earth, but virtually all of the images ever submitted to LPOD come from North America, Europe and Japan. These two complementary ones were taken by Iranian amateur astronomers, one living in Tehran and one in Dubai. These exaggerated color views demonstrate well the color variations of the maria and also that there are few colors in the highlands except the brightness of rays. The highlands are relatively homogeneous in composition because they were all created as a global crust when the Moon was molten. The energy for melting came from the millions of collisions that accreted the Moon from ejecta from a giant impact onto the proto-Earth. Maria have a greater range of compositions because their magmas formed at different times, at different depths and with different degrees of melting. And these two Iranian Moons help us understand that.
