English: This photo is Figure 4-23 of the Apollo 16 Preliminary Science Report (NASA SP-315), which has the following caption:
Color-enhanced far-UV photograph of the (Large) Magellanic Cloud. Ultraviolet radiation from specific astronomical targets was recorded on special spectroscopic black-and-white film in the far-UV camera/spectrograph. This photograph of the Magellanic Cloud, the nearest neighboring galaxy to the Milky Way, has been color enhanced to facilitate interpretation. Areas of similar intensity, recorded as a narrow range of gray tones on the black-and-white image of the UV-sensitive film, are reproduced as a color. In this photograph, blue areas indicate UV radiation levels below the threshold of detectability. Several other levels of UV intensity are indicated by different colors, such as red (faint UV), yellow (stronger UV radiation), and orange (most intense UV radiation within this field of view).
