Zipping along at 200,000 km per hour, the Juno spacecraft takes two hours to

pass from pole to pole.

In that time, it records a variety of readings of a world that remains a

gargantuan work in progress.

Winds up to 650 km per hour whip cold clouds of methane, hydrogen

sulfide, water and other compounds into endlessly swirling works of art.

Sometimes white clouds of ammonia snow fly over the wide southern red band,

making it seem to disappear from Earth's point of view.

It's cold in the clouds.

about minus 125 degrees Celsius.

Deep within the atmosphere, showers of compressed carbon may fall between the

layers in a diamond rain.

White spots mark the crests of enormous waves rising and falling along the

surface.

Twirling storms explode into the upper atmosphere, propelled by heating

hundreds of kilometers below.

They unleash lightning bolts far larger and stronger than any seen on Earth.

It's the polar regions, photographed for the first time ever by Juno, that have

defied expectations.

Here, the belts and zones of the middle latitudes disappear and the atmosphere

is dominated by an ensemble of hurricanes.
