A color image showing a pale tan-orange rock surface, which is smooth in some areas and rough, and layered in others, like a stucco wall. Resting atop the surface are lines creating various shapes – a hexagon dominating the image center, a diamond nestled below that, others off to the lower right and right sides of the image. These lines trace areas making them look like walled gardens viewed overhead from a great height.

A graphic illustration of the rover known as VIPER. It is mostly grey with blue siding and the central structure is box-like. Four wheels are underneath the rover, which will help it traverse the lunar south pole. Mounted on top of the rover are a couple of additional small structures as well as lights that will shine the way in permanently shadowed regions (PSRS). In the background is a simulation of the Moon�s surface surrounded by black space.

A large galaxy is at center, and a significantly smaller galaxy is to its left. The large galaxy, nicknamed the Bullseye, is mostly face-on, but the top appears slightly tilted away. It has several rings. Its circular core is bright white at the very center, but light yellow overall. Going outward, there are gaps between the rings. The core is surrounded by two slightly lighter yellow rings, which also appear to be overlapping. The next ring is slightly more transparent and yellow. The two or three rings that are farther out are bluer, sometimes with blue clumps. The widest ring is also blue, but also the most transparent. At 9 o’clock is a small dwarf galaxy. It is about the same size as the yellow core of the Bullseye. The dwarf galaxy is blue, with many dots. It looks like the edge of the Bullseye might touch the dwarf galaxy. Both galaxies are set on the black background of space, which is dotted with a range of galaxies in different shapes, colors, and sizes, along with one foreground star at left.

In the exact center a supernova is visible as a small but bright blue dot. It lies atop the outer disk of a hazy-looking galaxy, which has a somewhat warped shape. Around this are a number of minor galaxies visible as glowing disks, and some points of light that are stars near to us, on a black background. A few bright stars hold X-shaped spikes that are optical artefacts from the telescope.

Cassiopeia A, a circular-shaped cloud of gas and dust with complex structure. The inner shell is made of bright pink and orange filaments studded with clumps and knots that look like tiny pieces of shattered glass. Around the exterior of the inner shell, particularly at the upper right, there are curtains of wispy gas that look like campfire smoke. The white smoke-like material also appears to fill the cavity of the inner shell, featuring structures shaped like large bubbles. Around and within the nebula, there are various stars seen as points of blue and white light. Outside the nebula, there are also clumps of yellow dust, with a particularly large clump at the bottom right corner that appears to have very detailed striations.

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.
