Hundreds of small galaxies against the black background of space. Several white spiral galaxies are near image center. Most of the galaxies are various shades of orange and red, and many are too tiny to discern a shape. A handful of foreground stars show Webb's six diffraction spikes.

An illustration of a star being torn apart by a black hole. To the right of center, there is a black sphere representing a black hole, surrounded by many thick wisps of light. To the left of it, there is a fuzzy, bright white object representing a star. The star has a tail of gas coming off its right, which is brightest near the star, but becomes grayer further away. This tail flows into the black hole’s right side and swirls around the black hole in a horizontal disk. The disk is thicker toward its center and more diffuse farther away. Material in the disk also appears to wrap around the top of the black hole. Above and below the black hole, there are purple rays of light that extend upward and downward in two broad cones. This scene sits amid a black backdrop of space with many dim, white stars in the background.

A clumpy dome of blueish-gray clouds rises about a third of the way from the bottom. Above it, streaky, translucent red wisps brush upward to about halfway up the image. The top half of the image is the black background of space with one prominent, bright white star with Webb’s 8-point diffraction spikes. Additional stars and galaxies are scattered throughout the image, although very few are seen through the thick clouds at bottom and all are significantly smaller than the largest star.

A side-by-side image showing opposite sides of Jupiter. At the top, left corner of the left-hand image is the label Jupiter. Centered at the bottom is the label January 5, 2024. The planet is banded in stripes of brownish orange, light gray, soft yellow, and shades of cream. Many large storms and small white clouds punctuate the planet. The largest storm, the Great Red Spot, is the most prominent feature in the left bottom third of this view. To its lower right is a smaller reddish anticyclone, Red Spot Jr. Another small red anticyclone appears near the top center of the image. On the right panel, centered at the bottom is the label January 6, 2024. This opposite side of Jupiter is also banded in stripes of brownish orange, light gray, soft yellow, and shades of cream with many large storms and small white clouds punctuating the planet. At upper right of center, a pair of storms appear next to each other: a deep-red triangle-shaped cyclone and a reddish anticyclone. Toward the far-left edge of this view is Jupiter's tiny moon Io. The variegated orange color is where volcanic outflow deposits are seen on Io’s surface.

A face-on spiral galaxy with four spiral arms that curve outward in a counterclockwise direction. The spiral arms are filled with young, blue stars and peppered with purplish star-forming regions that appear as small blobs. The middle of the galaxy is much brighter and more yellowish, and has a distinct narrow linear bar angled from 11 o’clock to 5 o’clock. Dozens of red background galaxies are scattered across the image. The background of space is black.
