As we continue our #nebula week -- here we have the Cat’s Head Nebula a diffuse nebula located within the Carina Nebula in the #constellation... Carina! Listen to this week's #podcast to learn more about types of nebulae here […] [Original post on universeodon.com]
Image Description from source in toot: (right) Mid-Infrared Light - Webb. 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.

 

(middle) Near-Infrared Light - Webb. Near-infrared image of the Cat’s Head Nebula by the James Webb Space Telescope. An orange-brown 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 squarish dust cloud. The cat’s head is turned toward the right, revealing a yellow glowing eye. The background is mostly blue, with the top right corner revealing the black background of space. On the cat’s left are ghostly filaments of dust. Scattered throughout the view are many yellow and blue stars, some with Webb’s signature eight-point diffraction spikes, and a few faint background galaxies.

 

(center) Visible Light - Hubble. Visible-light image of the Cat’s Head Nebula by the Hubble Space Telescope. A dark brown, opaque 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 cat’s head is turned toward the right, revealing a red glowing eye. The top half of the background is bright blue. Approximately halfway down, cutting diagonally across the frame, the background color changes from blue to yellow, orange, and finally red near the bottom. The image is dotted with many small stars. Some larger stars with the telescope’s characteristic four-point diffraction spikes are scattered in the background and foreground.
