This Hubble image shows NGC 941, an intermediate spiral galaxy some 55 million light-years away in the constellation of Cetus. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) in the near-infrared and optical parts of the spectrum. Two 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 / C. Kilpatrick.
