By Saturn's Hexagon!
At last—a new oath for space opera heroes! And a really cool feature on Saturn's north pole—an enormous hexagonal feature, viewable in the infrared, that rotates along with the planet's rotation. Check out the Saturn hexagon at JPL's web site, including motion picture images from the Cassini spacecraft. (Thanks, Charlza, for the link.)
There are the usual typical scientific attempts by scientists to explain the phenomenon (atmospheric vortexes, dynamical patterns, blah-blah-blah). Nobody even mentions the most obvious explanation:
It's a giant hex-wrench socket left by aliens! They're storing the brains of abductees in the center of Saturn!
My God, what else might they be doing???
