Unnamed Double-Ring Basin (Natural Colors; credits: Lunexit)

This spectacular approx. 290-Km-diameter Double-Ring Basin seen in detail for the first time during MESSENGER's 3rd flyby of Mercury bears a striking resemblance to Raditladi Basin, observed during the 1st flyby.
This still-unnamed basin is remarkably well preserved and appears to have formed relatively recently, compared with most basins on Mercury. The low numbers of superposed impact craters and marked differences in color across the basin (seen in this enhanced color image released earlier this week) suggest that the smooth area within the innermost ring may be the site of some of the most recent volcanism on Mercury.
