The signs on the poles of Jupiter are fascinating and bear further investigation - NASA’s Juno satellite has of course been the greatest help here. Yet another sign just one orbital out - captured most recently in high detail by flyer Cassini - is even more remarkable.
The North pole of Saturn, the sixth planet, boasts a distinctly perfect geometrical hexagon - a 6-sided object, complete with definitive edges and perfect angles.
What natural phenomenon coincides other than intelligent life?
An appropriate response given this pattern in the solar system might be to construct a Triangle made of mirrors or flares on the South pole of Earth. Gauss suggested this exact shape, oddly enough.
As the poles are a location where radiation is very high one might harvest the energy using Tesla Towers, perhaps. Lights!
