The Moon in Enhanced Color
SEP 22, 2010
The Moon seems basically white as we look at it high in the night sky.
But, it actually has a varied mineral composition that produces a variety of
colors---it's just that the color variations are too subtle for our human
eyes. But, one can take a color picture of the Moon and then enhance the
colors in software to reveal the varying colors and hence composition of the
Moon's craters and maria. In this picture, areas that are blueish are high
in titanium oxide. Scientists do not yet fully understand why large areas
of lava flow are rich in titanium oxide. The answer will surely contain
clues about the origin of the Moon and perhaps the Earth as well.
