Just found out the Moon literally cracked open billions of years ago! NASA’s new images show giant valleys (grabens) wrapping around an ancient lunar sea, proving a huge chunk of the Moon’s crust was pulled apart by heavy lava flows. Turns out, our favorite nightlight has been stretching, shrinking, and reshaping itself for ages—and it’s still happening in some spots! Wild to think the Moon’s surface is basically a giant stress map from its dramatic past. #Science #MoonMysteries #NASA
