Colour Info: These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample narrow and broad 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: Red: F470N, Red: F405N, Yellow: F356W, Green: F212N, Cyan: F187N, Blue: F090W”
