Near the top center of this image is the crater Amaral, recently named for
the Brazilian modernist painter Tarsila do Amaral, who lived from 1886 to
1973 (see PIA11762). Amaral crater, with its smooth floor, surrounding ejecta,
and small secondary craters, appears noticeably younger than the heavily cratered
surface around it. Along with a smooth crater floor, Amaral also has a
central peak. Bright material on this peak is of particular interest to
members of the MESSENGER Science Team, as it appears to have an unusual
color in images acquired in the 11 color filters of the Wide Angle Camera
(WAC). In this previously released enhanced color image of Mercury (see
PIA11219), the central peak of Amaral (just below center left) appears as a
bright blue color in striking contrast to the otherwise orange tones of
surface material nearby. The different color of the central peak likely
indicates rocks with different chemical composition from those on the
neighboring surface.
