Saturn snowflake

A big space mystery is in the news. What is on the north pole of Saturn? Scientists have no idea.

As a total amateur, it seems obvious to me it's some kind of snowflake. Permanent and wider than three Earths, but a snowflake nonetheless.

my ignorant reasoning is:
  • on Earth, snowflakes sometimes appear as hexagons
  • Saturn's rings are made of ice
  • Saturn's density lowers as you get to the poles, becoming lighter than water but more than steam
Yet, no-one is even saying this even to refute it. As of right now, Googling saturn snowflake (or here) returns no significant entries.

To me, it even looks like a snowflake. Is it possible NASA scientists are idiots?
