This image displays a sequence of seven distinct phases of the Moon aligned horizontally against a pitch-black background. From left to right, the phases transition smoothly from the waxing crescent, through the first quarter and waxing gibbous, to the full moon at the center, then waning gibbous, last quarter, and waning crescent. Each lunar surface is shown in detailed grayscale, highlighting craters and mare regions, demonstrating the gradual changes in illumination. The stark contrast between the bright lunar surface and the black sky creates a clear and educational depiction of the Moon’s monthly changing phases.
