Six Hubble images of distorted galaxies are organized in a two-row mosaic. From left to right, the top row of galaxies appears as follows: The left panel has a galaxy that resembles the number nine tilted on its side to the left and has red-orange regions scattered with blue knots. The center square shows an edge-on spiral galaxy appearing like a white thin bar extending from 8 ou2019clock to 2 ou2019clock. It has a bright, compact core and a small background spiral galaxy just below the core. The right panel shows two merging galaxies forming a convoluted shape that extends from 8 ou2019clock to 2 ou2019clock. The bottom row of galaxies appears as follows: Left square contains a face-on spiral with faint, broad arcs of material to its left and right. The center panel has a hazy white, face-on spiral with a lumpy vertical line to its right that appears to curve around its core. The right panel shows an orange elliptical galaxy with a lumpy blueish galaxy curving around it to the right.

$Image shows a large spiral galaxy that that has a bright white center, with several lanes of reddish-brown dust and gas in between faint white arms. The galaxy takes up the center third of the frame. There are several thousand stars, some with diffraction spikes, scattered around the image. This image is labeled Hubble. A small box outlining an area at the center of the galaxy leads a pullout square at the top right. The image, labeled Webb, is dark with a white glowing oval at the center.$

A region of space is filled with stars and clumps of glowing orange and tan dust. A small portion of the sky at the center of the image is outlined with a white box. Lines extend from the corner of the box to the inset panel at the top right showing a magnified version of the outlined portion of the image. In the inset, there are smatterings of dim whitish-blueish stars and about seven glowing red orbs across the center in a line. Also across the center of the inset is a green glow. The background of the image is filled with stars and galaxies of various shapes and colors.

James Webb Space Telescope image showing a broad area of space with many small galaxies, four of which are highlighted in pull-out boxes. The four highlighted galaxies are very small, appearing as points of light. Black areas of the overall image indicate where the telescope did not collect data - a vertical section in the center and a square in the lower left corner.

$This release features a composite image of a galaxy cluster first discovered on New Year's Eve day, 2020. The cluster appears here as a large collection of brilliant white lights, each a distinct galaxy. A neon purple cloud stretches across the cluster's crowded core. Many of the hundred-plus galaxies in the cluster are in two clumps of galaxies towards the top and bottom of center. Some are encircled by a faint glowing haze, while a few foreground stars gleam with diffraction spikes. Some of the smaller galaxies are tinted blue, orange, or red, and some appear more oblong than round, suggesting spiral shapes viewed edge-on. The neon purple cloud sits at the heart of the image, surrounding the most densely-packed part of the cluster. This cloud, which spreads vertically across the cluster, is multimillion-degree gas observed by Chandra. The two clumps of observable galaxies, and the spread of superheated gas, reveal that the Champagne Cluster is in fact two clusters in the process of colliding. With the two clusters of sparkling light clinking together, and the auspicious discovery date, astronomers have dubbed the merged cosmic structure "The Champagne Cluster".$

This Webb image shows two interacting galaxies. NGC 4490 occupies the left side of the image, while NGC 4485 appears as a white glowing hue in the top right of the field. Both galaxies are connected by a bright stream of red stretching from the top left of the image, through the bottom center, and ending at the right under galaxy NGC 4485. There are regions of bright blue ionized gas visible in concentrated areas of the red stream. The background is black with multiple galaxies in various shapes throughout.
