Summary
[edit]DescriptionJupiter from Voyager 1 PIA02855 thumbnail 300px max quality.ogv |
English: Jupiter seen by Voyager 1 probe with blue filter. One image was taken every Jupiter day (approximately 10 hours). These pictures were taken from 01/06 to 02/03, 1979 ; and Voyager 1 flew from 58 million to 31 million kilometers from Jupiter during that time. The small, round, dark spots appearing in some frames are the shadows cast by the moons passing between Jupiter and the Sun, while the small, white flashes around the planet, are the moons themselves.
This Theora OGG movie was downscaled to half size and then transcoded at the maximum possible quality from the original NASA GIF animation at http://photojournal.jpl.nasa.gov/browse/PIA02855.gif linked from http://photojournal.jpl.nasa.gov/animation/PIA02855, see Source below for details. Suggested for English Wikipedia:alternative text for images: animated view of planet getting larger. These pictures were taken every 10 hours over 28 days in 1979; each frame shows Jupiter at the same local time with the Great Red Spot appearing stationary within its cloud belt while clouds move right to left past it; other cloud belts move left to right. The small, round, dark spots appearing in some frames are the shadows cast by the moons passing between Jupiter and the Sun, while the small, white flashes around the planet, are the moons themselves.Français : Vue animée de la planète Jupiter prise par Voyager 1 avec un filtre bleu. Ces image ont été acquises entre le 6 janvier et le 3 février 1979 à raison d'une image par jour jovien (10 h environ). Durant cette période, Voyager 1 s'est rapproché de Jupiter de 58 à 31 millions de km. Les petits points noirs visibles de temps à autres sont des ombres portées par les satellites joviens sur la surface de la planète. Les taches blanches dans le ciel sont les satellites eux-mêmes.
