This photo, taken by Voyager 2, shows a color composite of three photographs taken through blue, green and orange filters. Voyager 2, launched in 1977, photographed Jupiter in 1979, Saturn in 1981, Uranus in 1986 and Neptune in 1989. What it did not clarify was the pronunciation of Uranus, which can cause some giggles. Some astronomers stress the first syllable of the word: in other words, yoor-uh-nuhs. However, it is acceptable to pronounce the name of the planet with an emphasis on the second syllable as well.
