Seeing in the Dark

images by Paolo Lazzarotti, Massa, Italy

Under a very dark sky, I have heard, you can see by the starlight. And certainly the full Moon makes enough illumination to take midnight hikes. Somewhere between those extremes are the shadowed areas within lunar craters. The shadows are inky black, without an atmosphere to scatter light, but are the shadowed areas completely black? The answer is doubly no. We know that the very sensitive camera on the Kaguya orbiter could image the always shadowed floor of Shackleton. And now we see that some Earthly cameras can also penetrate lunar shadows. Paolo manipulated one of his normal high quality Chuck Wood
