ALT An image of the Earth, a round ball, set against the blackness of outer space. Through swirling clouds, the continent of Africa and the island of Madagascar can be seen; Antarctica is just visible at the very bottom of the Earth, and the Arabian peninsula at the top. The Atlantic and Indian Oceans are a deep, rich blue, giving this photo its common name: the Blue Marble.

ALT A crowded galaxy field on a black background, with one large star dominating the image just right of center. Three areas are concentrated with larger white hazy blobs on the left, lower right, and upper right above the single star. Scattered between these areas are many smaller sources of light; some also have a hazy white glow, while many other are red or orange. Even without zooming in, different galaxy shapes are detectable, like spirals, ovals, and arcs.
