This square astronomical image is divided horizontally by a waving line between a white-orange cloudscape forming a nebula along the bottom portion and a comparatively blue-purple-pink upper portion. From the nebula in the bottom half of the image, an orange cloud shaped like a horsehead sticks out. In the bottom left of the image, a white round glow is visible. The clouds from the bottom half of the image shine purple/blue light into the upper half. The top of the image shows the black expanse of space. Speckled across both portions is a starfield, showing stars of varying sizes and colors. Blue stars are younger and red stars are older.

X-ray emission is a telltale signature of a growing supermassive black hole. This result may explain how some of the first supermassive black holes in the universe formed. These images show the galaxy cluster Abell 2744 that UHZ1 is located behind, in X-rays from Chandra and infrared data from JWST, as well as close-ups of the black hole host galaxy UHZ1.
