Unveiling the Hidden Layers of the Moon: Rover's Surprising Discovery
The Chang'e-4 lunar rover has revealed multiple layers of hardened lava beneath the Moon's surface, indicating a series of basalt eruptions that occurred billions of years ago. The layers, detected using lunar penetrating radar, suggest a gradual depletion of internal thermal energy that drove lunar volcanism over time. Thicker layers were found deeper down, while they thinned towards the surface. The findings provide further insights into the Moon's volcanic history and support recent discoveries of prolonged lunar volcanic activity. However, the timing of these volcanic events remains unknown, and the interpretation of low-frequency lunar penetrating radar data continues to be debated among space scientists.
