NASA recently released a picture which shows variations in the moon’s gravity field measured by its Gravity Recovery and Interior Laboratory (GRAIL) over three months in 2012. The red zones indicate mass excesses, the blue bits mean mass deficiencies, but really, what we get from looking at this image is is that the moon’s kind of a trippy place to go.
