An area in the Orion nebula filled with dark, puffy clouds. On the image’s right side is a large area of clouds crossed by a dark bar. The region glows in red and whitish colors lit by a protostar within. At the other side a large jet of material ejected by the protostar appears to be made of thin, wispy, blue, and pink clouds. A couple of foreground stars shine brightly in front of the nebula.

Photo mosaic of Andromeda galaxy and five regions of interest. A spiral galaxy spreads across the width. It’s tilted nearly edge-on to our line of sight, appearing as an extreme oval on its side. Its borders are jagged because the image is a mosaic of smaller, square images. The outer edges are blue, while the inner two-thirds are yellowish with a bright, central core. Dark, dusty clouds wrap around the outer half of the galaxy’s disk. At 10 o'clock, a smaller dwarf elliptical galaxy forms a fuzzy, yellow blob. There are about 200 million stars within the image. The background of space is black. There are what appears to be steps toward the bottom, mainly toward the middle, which indicates where no data were taken. Interesting regions: (a) Clusters of bright blue stars embedded within the galaxy; background galaxies seen much farther away; (b) NGC 206, a concentration of bright blue stars; (c) A young cluster of blue newborn stars; (d) The satellite galaxy M32; (e) Dark dust lanes across myriad yellow stars.

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.
