A gorgeous gibbous Moon rests above a ridge line near Cerro Pachón, the home of four NOIRLab-operated telescopes including NSF–DOE Vera C. Rubin Observatory; Gemini South, one half of the International Gemini Observatory, supported in part by NSF; and the SOAR Telescope of Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab. The particular beauty of the Moon and its features are visible in this delightful image. The dark splotches of ancient, basaltic flats known as maria splatter across our satellite. These features formed when basalt moved from the lunar interior to fill basins on the surface during a time of active volcanism on the Moon. On the left side of the Moon, as seen from this perspective, are the two famous maria: Mare Tranquillitatis (immediately above center left) and Mare Serenitatis (center left). These maria, respectively, were the landing sites for the first and last human visits to the Moon. On the upper left-hand edge of the Moon, the slopes and edges of the Moon’s other distinct feature, craters, appear starkly against the dark blue sky. One of the most distinct lunar craters, the massive Tycho crater, is in the upper right quadrant of the Moon in this image, flipped almost 180 degrees compared to the view from the northern hemisphere. Craters on the Moon are younger than the maria, and Tycho crater is particularly young, as evident by its sharp appearance.

The central region of a planetary nebula is shown in a box. Labels indicate “Shock waves”, “Outflow collisions”, and an “Ionised jet” in the dust on both sides of the nebula. Close to the centre, “Dusty torus” and “Ionised torus” are marked. In the very middle, a faint dot inside a blotchy pink cloud is labelled “Dying star”. Bright stars surround the nebula and can be seen through the dust layers.
