Clouds of Jupiter - Illustration - Jupiter's cloud tops at night - Illustration - Artist view of Jupiter's cloud summit. Above all, the Io and Europe satellites. This vantage point is from the same altitude as Jupiter's highest clouds where the atmospheric pressure is just a few millibars, about the same as that on the surface of Mars. High in the starry sky can be seen two of Jupiter's largest satellites - - volcanic Io and icy Europa. The scanty ether here gives little clue to the gargantuan pressures and tornado - force winds below. A giant lightning bolt passes between cloud layers driven by a 300 mph gale. Beneath the clouds lies a turbulent realm of molecular hydrogen and helium. Go deeper yet and this atmosphere eventually gives way to a deep, planet - wide ocean of liquid hydrogen
