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.

Six Webb images of little red dots are combined in a two-row mosaic. Each little red dot is centered within a square frame and lies against the black background of space. Each dot has a yellow-white circular core surrounded by a red, fuzzy ring. White text in the top left corner of each box lists the source’s name from the Webb surveys, and its redshift. From left to right, the top row reads CEERS 14448, z = 4.75; NGDEEP 4321, z = 8.92; and PRIMER-COS 10539, z = 7.48. The bottom row reads CEERS 20320, z = 5.27; JADES 9186, z = 4.99; and PRIMER-UDS 17818, z = 6.40.

A portion of Webb’s 2023 observation of Wolf-Rayet 140. A bright white hexagon is toward the bottom left-center. This is the two stars. Blue diffraction spikes point diagonally toward 8, 11, and 1 o’clock. Surrounding the central light are a series of regularly spaced rings. A segment of each of the rings at around 2 o’clock appears brighter. These bright patches form a line that travels to the upper right. A few blue background dots are on the black background of space.

Field of yellow galaxies of various sizes and distances on a black background. Two larger galaxies are prominent. Centered is a galaxy with a bright core and faint spiral arms coming off its top and bottom. To the lower right of the spiral is a ring galaxy with an apparent gap between its bright core and the ring oval of dust and gas surrounding it.
