The rings of Saturn are very well-known.
They're this gorgeous set of rings circling the planet.
These rings are made of ice crystals and that's one of the reasons that they're so bright and that they're so easily seen.
It turns out that Jupiter also has rings, but these rings are made of dust so they're hard to see.
In fact, they were only discovered by the Voyager spacecraft.
Before that, we didn't know that Jupiter had rings.
They're caused by small satellites that Jupiter has moving around the planet close in.
These satellites are releasing some dust from their surfaces and that dust forms the rings.
That's why they're so difficult to see from the Earth.
When you get close up with the spacecraft, they're obviously easier to see.
You might worry about Juno running into some of these rings as it makes its orbit, but it doesn't.
The orbit is oriented in such a way that it will not pass through these rings.
