High resolution map of the moon’s surface gravity, produced last December by Gravity Recovery and Interior Laboratory (GRAIL), published in three papers in the journal Science.

“What this map tells us is that more than any other celestial body we know of, the moon wears its gravity field on its sleeve.  When we see a notable change in the gravity field, we can sync up this change with surface topography features such as craters, rilles or mountains.”
