The mystery of Jupiter's coloured bands is finally solved!
The mystery underlying Jupiter's characteristic coloured bands has been solved thanks to data from Nasa's probe orbiting around the gas giant.
Several strong jet streams flow west to east in Jupiter's atmosphere, which are similar to Earth's jet streams.
However, unlike on Earth where the jet streams meander across the surface, Jupiter's jet streams are more even and straight.
There are also no continents and mountains below Jupiter's atmosphere to obstruct the path of the jet streams.
