Jupiter shows its true stripes

Aug. 27, 2019 -  
There’s a reason why Jupiter’s stripes are only skin deep. It turns out that the planet’s zonal winds -- the alternating east-west jet streams seen in photographs as colorful stripes -- only descend to 3,000 kilometers in the atmosphere. Magnetic fields can make fluids that conduct electricity (...
