Prominent oval feature, 14,000 km/8,500 mi wide and some 30,000 km/20,000 mi long, in the atmosphere of the planet Jupiter, south of its equator. It was first observed in 1664. Space probes show it to be an anticlockwise vortex of cold clouds, coloured possibly by phosphorus.

The flag is modelled on the Stars and Stripes of the United States' flag. The stripes represent the nine provinces at the time of liberation. Blue and white are the colours of Argentina and also of national hero, José Gervasio Artigas. Effective date: 12 July 1830. >>
