ISS captures lunar-like rock formation in Madagascar

An astronaut on the International Space Station snapped a striking image of the Saririaky anorthosite massif in southern Madagascar—an unusual patch of bright, Moon-like rock. Anorthosite, rare on Earth but common on the Moon, forms eye-catching features visible even to the naked eye. The photo aids scientists comparing Earth’s rocks to material collected from lunar missions, trying to piece together how both planets—and their tectonic histories—formed.

Why it mattersStudying these special rocks on Earth helps researchers make sense of the limited Moon samples brought back by astronauts. Comparing Earth’s geologic record to the Moon’s could shed light on how both worlds evolved.
