This composite image shows two interacting galaxies NGC 7752 and NGC 7753, collectively known as Arp 86. The image is composed of infrared, optical and ultraviolet observations from Hubble’s Advanced Camera for Surveys (ACS), the Dark Energy Camera (DECam) on the Victor M. Blanco 4-m Telescope, and the Sloan Digital Sky Survey (SDSS). Nine filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / Dark Energy Survey / J. Dalcanton.
