ALT Earth setting behind the Moon\u2019s horizon. Set against the blackness of space, the dark gray surface of the Moon arc across the image in the foreground. Beyond, a blue and white crescent Earth, oriented like a frown, fills the center of the image, with one tip disappearing beyond the lunar limb.

ALT Alt: Earth setting behind the Moon. The gray half circle of the Moon, pocked with craters, fills the majority of the image, brightening from darkness at the bottom to light gray at the top, stark against the blackness of space. A much smaller blue and white crescent of Earth, oriented like a frown, appears to touch the edge of the Moon at one tip near the 11 o\u2019clock region of the image.

ALT A full disk image of Earth, as seen from the Orion capsule. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. From about 8 to 9 o'clock, a large brown landmass is Africa, with the Iberian peninsula twinkling with lights just where the planet curves. At the 1 o'clock spot, aurora glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space. Credit: NASA/Reid Weisman
