The edge-on spiral galaxy UGC 10288 appeared to be a single object in previous observations. However, new detailed radio data from the NRAO's Jansky Very Large Array (VLA) revealed that the large perpendicular extension of UGC 10288's halo (blue) is really a distant background galaxy with radio jets.
This image of UGC 10288 in the foreground is created with data spanning optical, infrared and radio energies. Radio data are blue, and infrared observations from NASA's Spitzer Space Telescope and Wide-field Infrared Survey Explorer (WISE) are yellow and orange, respectively. Optical data from the Sloan Digital Sky Survey are purplish blue and show starlight; and optical data from the Kitt Peak National Observatory are rose and show heated gas.
