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.
