Multi-wavelength image of Westerhout 50 (red - radio, green - optical, yellow - soft X-rays, magenta - medium energy X-rays, cyan - hard X-ray emission). The eastern lobe X-ray image highlights the XMM-Newton data (with the brightening at the edge of the field of view cropped here to highlight the source emission). The western lobe X-ray image shows only partial Chandra coverage of part of the nebula. Image credit: Safi-Harb et al., arXiv: 2207.00573.
