This colorful view from NASA’s Cassini mission is the highest-resolution view of the unique six-sided jet stream at Saturn’s north pole known as “the hexagon.” This movie, made from images obtained by Cassini’s imaging cameras, is the first to show the hexagon in color filters, and the first movie to show a complete view from the north pole down to about 70 degrees north latitude.

This blog is devoted to legal, historical and human rights matters, in which issues of general concern are addressed freely and spontaneously. It is intended to further an informal exchange of views in the democratic spirit of freedom of opinion and respect for the opinions of others, in an effort to understand rather than condemn, to propose constructive solutions rather than grandstand. The perspective is both from inside and outside the box and the added value lies more in the questions than in the answers.
