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.

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

An illustration of the red supergiant star Betelgeuse, its companion star, and a dusty wake. The disk of a red-orange star is in the center. It is surrounded by a diffuse orange cloud representing its extended atmosphere. Below it about one stellar diameter away is a yellow dot representing a smaller companion star. From the companion, a dark red cloud wraps around in a counterclockwise direction. It begins very narrow and expands as it gets further from the companion, finally disappearing at the outer edge of the diffuse orange cloud around 10 ou2019clock. The words u201cartistu2019s conceptu201d are at lower right.

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