$Mid-infrared image of the Cat’s Head Nebula by the James Webb Space Telescope. A bluish-gray filament of dust is in the center, stretching from the bottom to almost the very top. It has a narrow, irregular shape that resembles a cat sitting with its back toward the viewer and a tail extending downward. The tail ends at the lower one-third of the image and widens to a triangular peak of dust. The cat’s head is turned toward the right, revealing a white glowing eye. The background is mostly red, with the top left and right corners revealing the black background of space. On the cat’s left is a dome-shaped grouping of faint filaments of dust. Scattered throughout the view are yellow and blue stars, some with Webb’s signature eight-point diffraction spikes.$

A shell of ghostly gas encapsulates a cloud of amber-colored gases that blow out in both directions from a central point. This makes the nebula look like a top-down view of two brain hemispheres inside a transparent skull. The scene is decorated with multicolor dots of light, representing distant galaxies and stars. The stars shown here have six points, characteristic of Webb images.
