it's tuesday september 20th 20 2022. I'm Jackson Bird today. How did Saturn get its jaunty tilt and cool rings? A new study says it could have been caused by a hitherto unknown ancient moon that got torn apart by its planet. Plus, new findings on just how much

misinformation is being spread on TikTok. Here's some cool stuff for your ride home.

1:06.5

We've long had many questions about Saturn. Chief among them, why is it tilted, about 27 degrees on its axis?

1:16.0

And where did those spectacular rings come from? And why are they, as some data has shown,

1:22.2

so much younger than the planet itself? Like billions of years younger. Those two hallmark features of the planet,

1:31.9

the tilt and the rings, already work in concert with one another. If it weren't for the rings,

1:37.4

it could be more difficult for us to visually observe that the planet is tilted. And if it

weren't for the tilt, we would barely be able to see those

1:45.4

rings, so thin as they are proportional to the planet itself. Proportional being the operative

1:52.0

1:59.1

of ice with some rock and metals. But are the two linked

2:03.7

in more ways than just convenience for our own observations? A new study published last week in the

2:10.2

journal Science thinks they might be, and further proposes that Saturn's rings are actually the

2:16.0

debris of an ancient icy moon that was knocked

2:19.6

off its path by a bigger moon and gobbled up by Saturn's gravitational pull, explaining

2:25.5

how Saturn got its tilts, how the rings formed, and why the rings are only about

2:30.9

a hundred million years old, while the planet itself is 4.5 billion years old.
