Acadia at 3 a.m.

Tom Wildoner captured this view on May 12 in Maine’s Acadia National Park. See bright Mars on the right.

A view of Mercury’s northern volcanic plains is shown in enhanced color to emphasize different types of rocks on Mercury’s surface. In the bottom right portion of the image, the 181-mile- (291-kilometer)-diameter Mendelssohn impact basin, named after the German composer, appears to have been once nearly filled with lava. Toward the bottom left portion of the image, large wrinkle ridges, formed during lava cooling, are visible. Also in this region, the circular rims of impact craters buried by the lava can be identified. Near the top of the image, the bright orange region shows the location of a volcanic vent.
