This composite image shows the distant galaxy merger IC 2431. 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 / W.
