Saturn set to lose rings

Saturn, as we all know, is the coolest planet. And much of its coolness stems from its very sleek, elegant rings. So it was with much alarm that we read a hypothesis: that in 2025, just 13 or so months from now... Saturn's rings may simply... disappear. Imagine that. It'd be like Rome without the Colosseum, or Ohakune without its giant carrot. Unthinkable. So what's going on here, are the rumours true, is this the manifestation of some kind of cosmic climate change writ large? To find out we welcome Ian Griffin. Astronomer and director of Otago museum.
