Samain Moon of the Winter Solstice
Perhaps my favorite photograph out of the way too many we took, maybe a couple thousand, digital allows profligacy, is this one. I took it at the command center for the 4 meter telescope at Cerro Tololo, the one which Brain Schmidt used, with two others, to prove the universe is not only expanding, but accelerating, an achievement for which the three together won a 2011 Nobel Prize. Polite, too.
