Raw images from Hubble and the Cerro Tololo Inter-American Observatory (CTIO) in Chile, which were later combined to generate a final image of the Carina nebula. (a) High-resolution image, taken in the light emitted by hydrogen atoms. (b) Image taken in the light emitted by sulfur atoms, assigned a reddish hue. (c) Image taken with a filter tuned to the light emitted by hydrogen atoms, given a greenish hue. (d) Image taken through a filter sensitive to light emitted by oxygen atoms, colored blue.
