From the brains behind brains on. This is the moment of um.

Answering those questions that make you go. The moment of um comes to you from APM studios. I'm Manneko Wilhelm. A friend of mine

once decided to make a model of the solar system with cake pops.

They were so cool!

The one that represented Earth was mostly blue, and the one for Jupiter was way bigger than Earth,

and kind of an orange-y red swirl. The trickiest one? was

Saturn. Can you guess why? Making the rings, of course! She melted some white chocolate and made it into a flat ring on a piece of wax paper.

And then when it cooled, she was able to lift it up and gently put it on the Saturn Cake Pop.

It wouldn't have been Saturn without at least one ring.

Can you imagine if Earth had rings?

My name is Regan from Toronto, Canada.

My question is, if the Earth had rings,

when you looked outside your window, would you see those rings?

My name is Linda Spilker.

I work at the Jet Propulsion Laboratory in Pasadena, California.

I'm a planetary scientist and also the project scientist for a mission called

Cassini. The Earth doesn't have rings so much of what we know about rings comes

from studying Saturn's rings and the Cassini spacecraft

spent 13 years in orbit studying Saturn's rings. Saturn has the biggest,

rightest, flashiest rings in the solar system.

They're made mostly out of tiny particles of water ice.

But embedded in that ice are also what you could think of is sort of like dirt.
