$The Champagne 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.

This XMM-Newton image shows an X-ray view of the interstellar comet 3I/ATLAS. At the center of the image, a bright red spot stands out against a dark background, like a fiery beacon. Starting from this core, faint gradients of purple and blue spread outward, creating a slightly rotated rectangular frame, divided by a thin horizontal line, the detector gap. The red color shows low-energy X-rays, blue marks empty space with very few X-rays. Image credit: ESA / XMM-Newton / C. Lisse / S. Cabot / XMM ISO Team.

In the center of the image, the stars cluster to form a bright and dense green candy floss-colored haze, that is the Large Magellanic Cloud. Scattered across the middle of the image are about 50 small yellow crosses, some of them are so close to one another that they almost overlap. SNR J0624-6948 (orange, higher in the image) and SNR J0614-7251 (blue, lower in the image) are seen in the lower left quarter of the image.

This artist impression shows ultra-fast winds blasting out from the center of galaxy Markarian 817. These winds, moving at many millions of km per hour, clear out interstellar gas from a vast region of space. Without this gas, the galaxy can’t form new stars and the black hole in the galactic center has little left to eat. The inset shows what is happening at galaxy’s heart. A supermassive black hole draws in gas from its surroundings, which forms a hot, brightly lit accretion disk (orange). The cause of the winds (white) is magnetic fields within the disk, which fling particles out in all directions at incredibly high speeds. These winds effectively block out X-rays (blue) which are sent out by the extremely hot plasma surrounding the black hole, called the corona. Zak et al. caught Markarian 817 blasting out ultra-fast winds using ESA’s X-ray telescope XMM-Newton. Lasting for around a year, the winds will have significantly affected star formation in the galaxy. The fact that the black hole at the center of the galaxy was showing rather average activity levels before producing the winds suggests that ultra-fast black hole winds are much more common than previously thought. In other words, black holes and their host galaxies strongly affect each other’s evolution. Image credit: ESA / CC BY-SA 3.0 IGO.

IXPE and Chandra images have been combined to show X-ray data of the area around Sagittarius A. The lower panel combines IXPE data, in orange, with Chandra data in blue. The upper panel depicts a much wider field-of-view of the center of the Milky Way. The thin white lines layered onto the top panel frame the highlighted area, and indicate that the perspective in the bottom panel has been rotated approximately 45 degrees to the right. The combination of IXPE and Chandra data helped the astronomers determine that the X-ray light identified in the molecular clouds originated from Sagittarius A* during an outburst approximately 200 years ago.

This artist’s illustration depicts what Chu et al. think is happening in the binary system KPD 0005+5106. The data suggest the white dwarf (blue sphere) is blasting a companion object (brown and red object on right), which is either a low-mass star or planet, with waves of heat and radiation. The white dwarf is also pulling material from the companion into a disk around itself, which the artist shows in orange, before it slams into its north and south poles. This process is contributing to the destruction of the companion through powerful gravitational forces. Image credit: NASA / CXC / M. Weiss / ASIAA / Chu et al.
