00:05.000 --> 00:08.050
The rings of Saturn are very well-known.

00:08.050 --> 00:12.450
They're this gorgeous set of rings circling the planet.

00:12.450 --> 00:18.200
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.

00:18.200 --> 00:24.130
It turns out that Jupiter also has rings,
but these rings are made of dust so they're hard to see.

00:24.130 --> 00:27.400
In fact, they were only discovered by the Voyager spacecraft.

00:27.400 --> 00:30.550
Before that, we didn't know that Jupiter had rings.

00:30.550 --> 00:37.580
They're caused by small satellites that Jupiter
has moving around the planet close in.

00:37.580 --> 00:44.000
These satellites are releasing some dust from their surfaces
and that dust forms the rings.

00:44.000 --> 00:47.580
That's why they're so difficult to see from the Earth.

00:47.580 --> 00:52.000
When you get close up with the spacecraft,
they're obviously easier to see.

00:52.000 --> 00:58.100
You might worry about Juno running into some of these rings
as it makes its orbit, but it doesn't.

00:58.100 --> 01:03.000
The orbit is oriented in such a way
that it will not pass through these rings.
