The waxing Moon just before first-quarter phase, as it appears in an amateur telescope magnifying about 40 times. (On Christmas Day, the Moon will be just past first-quarter.) The Moon changes phase from night to night, revealing new lunar landscape every step of the way. When the Moon is waxing, it’s visible in the evening and growing wider each night — as the terminator (the line that divides night and day on the lunar surface) unveiling more and more of the blasted, alien landscape.
Maybe you just got a shiny new telescope to call your own. Congratulations — you
