![Video still frame from a sonification of the Southern Ring Nebula. Two views of the same object, the Southern Ring Nebula, are shown side by side. Both feature black backgrounds speckled with tiny bright stars and distant galaxies. Both show the planetary nebula as a misshapen oval that is slightly angled from top left to bottom right. At left, the near-infrared image shows a bright white star with eight long diffraction spikes at the center. A large transparent teal oval surrounds the central star. Several red shells surround the teal oval, extending almost to the edges of the image. The red layers, which are wavy overall, look like they have very thin straight lines piercing through them. At right, the mid-infrared image shows two stars at the center very close to one another. The one at left is red, the one at right is light blue. The blue star has tiny diffraction spikes around it. A large translucent red oval surrounds the central stars. From the red oval, shells extend in a mix of colors.](https://science.nasa.gov/wp-content/uploads/2024/02/stsci-01h2gef91p07exzwrdh4xb10wp.png?w=4096&format=png)

At left, a mottled light pinkish-orange oval whose inner edge resembles a string of pearls. Within the oval is a dense blue-green cloud, shaped like a keyhole. Three stars with six-point diffraction patterns surround the oval. Above and below these structures, are very faint orange rings, which form a figure eight pattern. The center of the supernova remnant is surrounded by a white box with lines leading to the upper and lower right of the image, where two stacked panels show a bright orange ring with an orange dot in the middle. The upper panel is fuzzier and more blobby, while the bottom panel has more clearly defined edges around the ring and central dot.](https://science.nasa.gov/wp-content/uploads/2024/02/stsci-01hphqmcmzgtx4pxe5tzccbehq.png?w=4096&format=png)

All three galaxies appear to form thin lines that take up less than a quarter of the frame. The galaxy at top left has a horizontal thin line with two dots beneath it; the center galaxy is a short line from top left to bottom right made up of individual dots, with a haze toward the center-left; the right galaxy is the longest line angles from top left to bottom right, and several dim dots above it. Along the lower row, the galaxies at left and center, labeled disk-like appearances, have hazy spiral shapes, and each take up about half of the frame. The galaxy at lower right, labeled spherical appearance, looks like a bright dot centered in the frame and is far smaller.](https://science.nasa.gov/wp-content/uploads/2024/02/stsci-01hhz8tvcpcysd1dqfqkmsvqtr.png?w=4096&format=png)

Some of the gray material forms a curved feature in the upper right and is marked with a yellow line labeled “cat’s tail.” The central star, represented as a small white star icon, is blocked by an instrument known as a coronagraph, which forms a large black circle at center and two small disks pointing to the upper left and lower right.

The top left galaxy appears circular and light pink with a slightly whiter central region, taking up less than one-sixth of the box. The bottom galaxy is elongated, stretching almost from top left to bottom right. It has a white line at the center that has a pink outline that transitions into and bluish edges at far left and right. Thin lines from each magnified galaxy point their appearances in the broader field. The top galaxy appears as a tiny dot at the upper center, and the bottom galaxy toward the left. Thousands of galaxies appear across most of this view, which is set against the black background of space. There are many overlapping objects at various distances. They include large, blue foreground stars, with Webb’s signature eight-pointed diffraction spikes, and white and pink spiral and elliptical galaxies. Numerous tiny red dots appear throughout the scene.

Two slits in each pattern will allow the mirrors to be concave when cut out and glued together. The following instructions are listed next to the mirror images: "You'll need a strip of paper 12mm (0.47 inches) wide and 340mm (13.3 inches) long. Make about 6 gluing tabs along the longer side. This strip will go into the hole on the front panel of the backplane and will act as a spacer to accommodate the curvature of the mirror. (see page 5 of assembly manual) Fold the tabs towards the center of the circle and glue one side to the back of the 'back plane' and the other to the back of the mirror."](https://science.nasa.gov/wp-content/uploads/2023/12/jwstmodel-tom-mirrors.jpg?w=4096&format=jpeg)

![At the center is a thin horizontal pinkish cloud known as Herbig-Haro 211 that is uneven with rounded ends, and tilted from bottom left to top right. It takes up about two-thirds of the length of this angle, but is thinner and longer at the opposite angle. At its center is a dark spot. On either side of the dark spot, there are orangish yellow wisps that extend to light blue wisps. Within the center of those clouds, a pink fluffy streak runs through each lobe. At the ends of each lobe, pink becomes the dominant color. The lobe to the left is fatter. The right lobe is thinner, and ends in a smaller pink semi-circle. Just off the edge of this lobe is a slightly smaller pink semicircle, then a pink sponge-like blog. The background contains several bright stars, each with eight diffraction spikes extending out from the central bright point.](https://science.nasa.gov/wp-content/uploads/2023/09/sep-14-23-stsci-j-p23141a-m-2k.jpg?w=4096&format=jpeg)
