A few dozen white stars, some with Webb’s signature 8-point diffraction spikes, on the black background of space. Tightly packed, red-orange filaments extend horizontally from upper left to lower right, with a bulging upward curve on the right that is closer to the top. The filaments resemble wood grain.

A spiral galaxy filling the view. Its disk holds many bright red spots where stars are forming, dark reddish threads of dust that obscure light, and bluish glowing areas that hold concentrations of older stars. It has a large, glowing yellow oval area at the center, from which two spiral arms wind through the galaxy’s disk. One side of the disk appears rounded (bottom of the image) while the opposite side appears somewhat squared-off (top of the image).

A spiral galaxy with an oval-shaped disk. Two large arms curve out away from the ends of the disk. Bright pink patches and dark reddish threads of dust fill the arms. The bright pink patches indicate where stars are forming. The core is very bright and filled with stars. Some large stars appear in front of the galaxy. Directly under the point where the right arm joins the disk, a fading supernova is visible as a green dot.

A close-in view of a barred spiral galaxy. A bright, glowing bar crosses the center of the galaxy, with blurred spiral arms curving away from its ends and continuing out of view. Bright points of light that indicate stars and background galaxies surround the featured barred spiral galaxy. The galaxy also hosts a bright supernova in its central bar, just right of image center.
