Or ravioli ( round ) or walnut . The spatial debate of the week is undoubtedly " what noses looks like Pan, " the Saturn moon that Cassini has just photographed. I choose the sandwich, unlike the Anglo-Saxon means, because calling itself Pan can not be anything else.
"When I first saw these photographs I also thought they had to be the paintings of an artist," Carolyn Porco, the head of images for the Cassini project, tweeted yesterday. But no, they are real and give us a very precise idea of the shape of the second innermost moon of Saturn.
A singular moon
We already knew that Pan had something strange. It is in the Encke division, a gap within one of the rings of Saturn created by its very existence. For years there has been much debate about the formation of Pan, Daphne and other small moons of the planet.
So far the images we had were not of high quality. Getting close to the rings is dangerous. But Cassini is approaching the end of his journey and is giving us the opportunity to know the gaseous giant better than ever. Too bad it's going to end soon.
