Recent discoveries of returned lunar samples to Earth from China’s Chang’e 5provide evidence for active volcanoes on the Moon as recently as 120 million years ago. Scientists had previously thought that magma activities on the Moon’s surface ended billions of years ago.

Here are key findings: Discovery of Young Ridges: Researchers identified 266 previously undocumented small ridges on the Moon’s far side. These ridges, located in volcanic regions formed 3.2 to 3.6 billion years ago, appear to have been tectonically active within the last 200 million years, with some activity as recent as 14 million years ago.

This is considered recent in the Moon’s geological timeline. Geological Activity Indicators: The ridges were found using advanced mapping and crater-counting techniques, which estimate surface ages based on crater density. Some ridges cut through existing craters, confirming their relatively young age.

This suggests ongoing tectonic processes, possibly linked to the Moon’s gradual shrinking and shifts in its orbit. Seismic Implications: These findings may explain shallow moonquakes detected during Apollo missions, indicating that internal forces are still shaping the lunar surface today.

Future Exploration Impact: Understanding this newfound geological activity is crucial for planning future lunar missions, including astronaut landings and infrastructure placement. It also highlights the need for tools like ground-penetrating radar to study subsurface structures.

These discoveries reshape our understanding of the Moon’s evolution and hint at a dynamic interior still influencing its surface. References: Amazouz, L. (2025, January 29). The Moon Is More Alive Than We Thought! Scientists Discover Signs of Recent Geological Activity.
