is normally seen in subtle shades of grey or yellow.
But small, measurable color differences
have been greatly exaggerated
to make this telescopic, multicolored,
moonscape captured during the Moon's full phase.
The different colors are recognized to
correspond to real differences in
the chemical makeup of the lunar surface.
Blue hues reveal
areas while orange and purple colors
show regions relatively poor in titanium and iron.
Sea of Tranquility, or Mare Tranquillitatis,
is the blue area in the upper right corner of the frame.
White lines radiate across the orange-hued southern lunar highlands
from 85 kilometer wide ray crater Tycho
at bottom left.
Above it, darker rays from crater Copernicus
extend into the Sea of Rains
at the upper left.
from the Apollo missions, similar multicolor
images from spacecraft
have been used to explore
Moon's global surface composition.
