Bill's Sky

The full Moon is tomorrow, tonights is at 98% full. I haven't bothered to look at it because this full there is low contrast with no shadows. Most features are harder to make out. Common wisdom is that there really isn't much to see like this. However, I had read that sometimes when the surface is this bright you can see hints of the faint mineral colors. Professional Astronomers use filters and processing images to bring out these faint colors.             " Even if the moon really were made of green cheese it probably wouldn’t look this bizarre. Still, this mosaic of 53 images was recorded by the Jupiter-bound Galileo spacecraft as it passed near our own large natural satellite in 1992. The pictures were recorded through three spectral filters and combined in an exaggerated false-color scheme to explore the composition of the lunar surface as changes in mineral content produce subtle color differences in reflected light.
