Astronomers may have uncovered a new supernova remnant in a star-forming region near the center of the Milky Way galaxy using data from Chandra and XMM-Newton. If confirmed, this would be one of the closest supernova remnants to the supermassive black hole in the Galactic Center. This image shows the region where the evidence was found, which contains X-rays from Chandra and XMM-Newton, radio data from the MeerKAT telescope in South Africa, and an optical image from the Pan-STARRS telescopes in Hawaii.

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