Research suggests moon may still be geologically active

Recent research indicates that the moon may still be geologically active. Scientists have identified 266 wrinkle ridges on the lunar far side, suggesting volcanic activity occurred within the last 160 million years, differing from the previously held belief that geological activity ceased billions of years ago. These wrinkle ridges are smaller than those on the near side, which is covered in large volcanic plains. The far side has only 1% of its surface as lava plains, leading to fewer and smaller geological features. The recent findings challenge earlier assumptions about the moon's geological history. Evidence from lunar samples returned by China's Chang'e 5 mission supports the idea of recent volcanic activity. This suggests the moon is still contracting and may experience moonquakes, which could impact future human activities on its surface.
