A supernova appears as a small but bright pink-white dot at the exact center of the image. It lies in a spiral galaxy, close to the glowing center and next to bright patches of blue stars in the galaxy. A few minor galaxies are visible around the comparatively large spiral as small glowing disks, while distant galaxies appear as mere orangish spots and smudges, all are on a black background.

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 a visualization, Earth is shown against the blackness of space. White lines emanate out from the poles showing the planet’s magnetic field lines. Concentric rainbow-colored semicircles on either side of Earth visualize belts of trapped electrons. The second belt from Earth is colored purple to indicate it’s composed of protons as well as electrons. The third belt from Earth (rainbow color) represents the new electron belt.

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.
