Saturn is the only competitor for most gorgeous planet with that giant ring system. Hmm… what if we could put the jewel of the Earth in its own ring? Then no contest. Well, there’s an extremely good chance that Earth once DID have a ring system. At least, that’s the proposal by a recent study that has evidence that a mysterious burst in meteor activity nearly half a billion years ago was actually caused by that ancient ring system collapsing onto the Earth. And, you know, if we had a ring once maybe we can have one again. Check Out Joe Scott’s: What Would Happen If The Earth Had Rings?
