Highlights

A grayscale image from the Martian surface shows rough terrain mostly covered in small stones and many slightly larger ones, whose exteriors are very bumpy in spots and more smoothly rounded in others. The horizon sits high in the image, starting at the left-center of the top of the picture and descending toward the right side of the image, ending about a quarter of the way from the top. A small, gently sloping hill rises from the horizon near the upper right corner of the image. A small section of sandy smooth soil, darker gray than the rest of the surroundings is visible in the lower middle of the frame, extending toward the middle of the picture's left edge. That patch is just beyond the Curiosity rover, a portion of which is visible in the lower left corner of the image.

A comet brightens and its tail grows as it moves from right to left against a black background of stars. A black disk appears at the bottom with a white circle drawn on its center. Faint streamers of coronal material extend away from the disk. A time stamp appears in the bottom left corner. The comet's name and "ESA/NASA SOHO/LASCO C3" appears in the upper right.

A collection of galaxies. On the right side a large spiral galaxy with swirling, twisted arms is flanked by a smaller, but still detailed, spiral behind its arm on the left, and a smaller spiral above it. On the left side is a fourth, round spiral galaxy seen face-on. Between them lies a single bright star. Several stars and distant galaxies dot the background.

An area in the Orion nebula filled with dark, puffy clouds. On the image’s right side is a large area of clouds crossed by a dark bar. The region glows in red and whitish colors lit by a protostar within. At the other side a large jet of material ejected by the protostar appears to be made of thin, wispy, blue, and pink clouds. A couple of foreground stars shine brightly in front of the nebula.

Photo mosaic of Andromeda galaxy and five regions of interest. A spiral galaxy spreads across the width. It’s tilted nearly edge-on to our line of sight, appearing as an extreme oval on its side. Its borders are jagged because the image is a mosaic of smaller, square images. The outer edges are blue, while the inner two-thirds are yellowish with a bright, central core. Dark, dusty clouds wrap around the outer half of the galaxy’s disk. At 10 o'clock, a smaller dwarf elliptical galaxy forms a fuzzy, yellow blob. There are about 200 million stars within the image. The background of space is black. There are what appears to be steps toward the bottom, mainly toward the middle, which indicates where no data were taken. Interesting regions: (a) Clusters of bright blue stars embedded within the galaxy; background galaxies seen much farther away; (b) NGC 206, a concentration of bright blue stars; (c) A young cluster of blue newborn stars; (d) The satellite galaxy M32; (e) Dark dust lanes across myriad yellow stars.

In this illustration, a small portion of the Sun appears in yellow at the bottom with a dark sunspot in the center. Above the sunspot, against a black background, appear several vertical, curved streaks of light that are light pink at the bottom, closest to the sunspot and darken to dark pink in the middle then purple at the top. The streaks also appear thinner at the top than at the bottom.
