This Hubble image shows NGC 3254, a spiral galaxy located some 118 million light-years away in the constellation of Leo Minor. 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). Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
