A recent study funded by NASA has shed light on a fascinating phenomenon - the Earth's moon is shrinking. Over the last few million years, the moon's circumference has decreased by approximately 150 feet, according to the study. Scientists believe that this shrinkage is due to the moon's core gradually decreasing in size as it cools, resulting in the surface wrinkling and creasing.
Comparing the process to a grape shriveling into a raisin, the researchers explain that the creases on the moon's surface lead to moonquakes and landslides, making the terrain less stable and significantly different from what scientists previously assumed. This new finding may have implications for future lunar exploration, particularly around the lunar south pole.
