New Evidence: Earth Had Rings (and Might Regain Them)
Season 11
Episode 1
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.
