Caption: Voyager 1 took this photo of the planet Jupiter on January 24, while still more than 25 million miles (40 million kilometers) away. As the spacecraft draws closer to the planet (about 1 million kilometers a day) more details are emerging in the turbulent clouds. The Great Red Spot shows prominently below centre, surrounded by what scientists call a remarkably complex region of the giant planet's atmosphere. An elongated yellow cloud within the Great Red Spot is swirling around the spot's interior boundary in a counterclockwise direction with a period of a little less than six days, confirming the whirlpool-like circulation that astronomers have suspected from ground-based photographs. Ganymede, Jupiter's largest satellite, can be seen to the lower left of the planet. Ganymede is a planet-sized body larger than Mercury. This colour photo was assembled at Jet Propulsion Laboratory's Image Processing Lab from three black and white images taken through filters.

Pořízení fotografie: Sonda Voyager 1 získala tuto fotografii planety Jupiteru 24. ledna 1979, když byla ještě 40 miliónů kilometrů vzdálená. Jak se kosmická loď blížila k planetě (asi 1 milión kilometrů za den), v tubulentních mracích se objevovaly stále nové a nové detaily. Nápadná Velká rudá skvrna zachycená pod středem obrázku je obklopená pozoruhodně složitými oblastmi atmosféry. Protáhlý žlutý oblak uvnitř Velké rudé skvrny víří proti směru hodinových ručiček s periodou méně než šest dnů, potvrzuje tak podobnost vodnímu víru, kterou astronomové předpokládali při pozorování ze Země. Jupiterův největší měsíc Ganymede je vidět poblíž levého spodního rohu obrázku. Podle velikosti by se Ganymede řadil spíše k planetám, je větší než Merkur. Tato barevná fotografie byla sestavena v laboratoři (Jet Propulsion Laboratory's Image Processing Lab) ze tří černobílých fotografií prohnaných filtry.
