An astronaut aboard the International Space Station has photographed a striking geological feature in Madagascar that closely resembles the Moon's bright highlands. The formation is made of anorthosite, a rock that is abundant on the lunar surface but uncommon on Earth.
The rock formation is estimated to be at least 600 million years old. Its presence on Earth offers scientists a natural laboratory to study processes similar to those that shaped the lunar crust.
Because this is a single report, there are no conflicting accounts to compare. The discovery highlights how orbital photography can reveal unexpected geological analogues on our own planet.
