This Hubble image shows ESO 021-G004, a spiral galaxy located approximately 130 million light-years away in the constellation Chamaeleon. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
