Money quote:

"... Saturn's thick atmosphere where circularly-shaped waves and
convective cells dominate is perhaps the last place you'd expect to see
such a ... figure, yet there it is."

Infrared movie of Saturn's hexagon.

It was IR, not radar.  The dots inside the hexagon rotate not quite as
fast as the overall rotation of the planet, and the ones outside maybe a
little faster.  There are too few frames to see what paths they take in
the long term.
