Three new Chandra sonifications of data of Jupiter, Saturn, and Uranus have been released. Planets and other Solar System bodies can reflect X-rays given off by the Sun, which Chandra can detect. Sonification is a process that translates data captured by Chandra and other telescopes into sound. In addition to X-rays from Chandra, these new sonifications contain data from Hubble, Cassini, and Keck telescopes. In this image, the amount of diffuse X-rays from a donut-shaped ring of energetic particles around Jupiter, seen on the left and right side of the planet, has been enhanced compared to the amount of X-rays from the planet's auroras, seen at the poles. As the scan moves left to right, it encounters X-rays that bracket the planet on either side, and this plays as woodwind sounds. As we pass over the planet itself, seen in an infrared image from NASA’s Hubble Space Telescope, the sounds become fuller as the infrared data is represented by other instruments. Since Jupiter is tilted slightly, the pitch descends as the scan passes over the bright band near the equator and through the Great Red Spot. On the other side, more X-ray data from Chandra flanks the planet and can be heard as gusty wind sounds at the end.

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

Webb near-infrared data combined with Chandra X-ray data of the Bullet Cluster show many overlapping objects, including foreground stars, galaxies in galaxy clusters, and distorted background galaxies behind the galaxy clusters. The objects are all at various distances set against the black background of space. Most galaxies appear as tiny fuzzy ovals in white, orange, or red. A slightly larger, very bright, light blue spiral galaxy is at center. To its immediate left and right are two large bright pink splotches representing X-rays. The right pink area has a rounded nose facing right, where it is darker pink, and fades to the left as a triangular shape. This is referred to as the Bullet. To the far left and far right, next to the pink regions, are two blue regions representing dark matter mass. The left blue region is a large, long oval at an angle. The blue region at right is a far smaller oval.
