A picture of Neptune taken by Voyager 2, showing off the Great Dark Spot which has since disappeared from the planet's surface.
Original Caption Released with Image: During August 16 and 17, 1989, the Voyager 2 narrow-angle camera was used to photograph Neptune almost continuously, recording approximately two and one-half rotations of the planet. These images represent the most complete set of full disk Neptune images that the spacecraft will acquire. This picture from the sequence shows two of the four cloud features which have been tracked by the Voyager cameras during the past two months. The large dark oval near the western limb (the left edge) is at a latitude of 22 degrees south and circuits Neptune every 18.3 hours. The bright clouds immediately to the south and east of this oval are seen to substantially change their appearances in periods as short as four hours. The second dark spot, at 54 degrees south latitude near the terminator (lower right edge), circuits Neptune every 16.1 hours. This image has been processed to enhance the visibility of small features, at some sacrifice of colour fidelity. The Voyager Mission is conducted by JPL for NASA's Office of Space Science and Applications.

Título original Liberado com imagem: Durante 16 e 17 de Agosto, 1989, o Voyager 2 a câmera de estreito-ângulo foi usada para fotografar Netuno quase continuamente, gravação aproximadamente duas e meia rotações do planeta. Estas imagens representam o mais completo grupo de imagens do disco cheio de Netuno que a nave espacial adquirirá. Este retrato da seqüência mostra duas das quatro características da nuvem quais foram seguidos pelas câmeras de Voyager durante os dois meses passados. O oval escuro grande perto do limbo ocidental (a borda esquerda) está em uma latitude de 22 graus ao sul e circuita Netuno cada 18,3 horas. As nuvens brilhantes imediatamente ao sul e leste deste oval são vistas para mudar substancialmente suas aparências nos períodos tão curtos como quatro horas. O segundo ponto escuro, a 54 graus de latitude sul perto do terminal (borda direita mais baixa), circuita Netuno cada 16,1 horas. Esta imagem foi processada para realçar a visibilidade de características pequenas, em algum sacrifício da fidelidade da cor. A missão de Voyager é conduzida por JPL para o escritório da NASA da ciência e das aplicações do espaço.
