Gna is the Nordic god that has the attribute of being swift. Swedish astronomers think they might have spotted a swift moving object at the edge of the solar system. Funnily enough a group of Mexican astronomers also think they have spotted something moving in the outer reaches of the solar system. Both teams have been looking at data from ALMA (a cluster of radio dishes in the mountains of Chile). Naturally, the non-Gna types are very quick on the draw – we must suppress such naughtiness (one can see the shock light up their earnest faces) and they are already on record as being highly sceptical rather than non-plussed (the natural response).
