Kristina from Science News writes"Combining computer simulations with data about the way starlight shines through Saturn's rings suggests the individual grains are big and thus could have been around a good 4 billion years, not the mere 10 million to 100 million previously suspected. What may have thrown earlier observations off is the chance that the grains aren't evenly distributed, but clump here and spread out there."
