Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

These images are a composite of separate exposures acquired by the WFC3/IR instrument on the Hubble Space Telescope. Several filters were used to sample particular wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are Cyan: F140W/F105W Orange: F160W
