This is very interesting - and unexpected (at least to me):

Apparently there may be small features of volcanic origin on the Moon that are less than 100 million years old. The images are also very interesting - I would probably never have guessed that the image at the top was of lunar terrain.

I was just enjoying the very interesting post by GoneToPlaid when I realized I had said almost the opposite higher up the page. But GoneToPlaid is correct here.

I was commenting a bit hastily regarding a common situation in spectral analysis of airless bodies. Surfaces are often described as red or blue, or redder or bluer, and in many cases the 'bluer' material is neutral, but closer to the blue end of the spectrum than the redder material so it gets described as blue or bluer and processed as blue in images.

In this case I completely accept that the surface may in fact be blue.
