This Hubble image shows SDSS J103512.07+461412.2, a spiral galaxy some 23 million light-years away in the constellation of Ursa Major. 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. It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / R. Tully.
