I found this link via Fark, and don’t think I can improve upon the submitter’s description:
Scientists spot “bizarre hexagon” on Saturn. As opposed to all the other normal hexagons on Saturn. In related news, Yahoo science writer actually writes, “This thing is a hexagon.”
One of the stories linked to from this article is even weirder, describing as it does a long-term storm with “an oddly human-looking hurricane-like eye.” Creepy.
