HST WFC3 Image of Supernova 1993J

About the colours

This image of SN 1993J is a composite of separate exposures acquired by the ACS/WFC instrument. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image as follows: Blue: F438W (B) Green: F555W (V) Red: F625W (r)
