Gaseous yellow-orange filaments look like a rose seen from the side and tilted slightly from upper left to lower right, slightly higher than the center of the frame. Extending from the rose to upper left and lower right are gaseous outflows that appear as red lobes that have an overall shape of tall, narrow triangles with rounded tips. Each red triangle is made up of wavy, irregular lines. Dozens of stars are scattered across the field. One particularly bright white star with eight diffraction spikes is located at the top of the yellow rose. Another bright blue star with even more prominent diffraction spikes is to its lower left. The background of space is black.

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.

Labeled "artist’s concept" at bottom right, the graphic shows a closeup of a dwarf galaxy, which appears roughly circular with a light yellow bar in the center. Faint, blue, wispy, cloud-like features surround this yellow bar, and they are sprinkled with tiny white specks. A wide, wispy, purple arc appears to the left of the galaxy. Trailing the galaxy is a large, faint, wide, tail-like  feature.
