This Hubble image shows the strong-lensing galaxy cluster SDSS J0901+1814. The lensed star-forming galaxy LRG-3-817 is seen as a long arc to the left of the cluster’s central galaxy. 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). Five filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
