NASA's LRO Reveals 'Incredible Shrinking Moon

Many of my designs incorporate nature, and one specifically the moon (filed under "Landscape").

I added a cluster of grass to make it more interesting and to depict a harvest moon, when the moon is at its brightest.

Nasa has an article and images on its website reporting that the moon is shrinking. And here is an interview (with a transcript) at NPR with space scientist Thomas Watters explaining the phenomenon.
