Hey, welcome to Stuff to Blow Your Mind.

My name is Robert Lamb.

Today is Saturday.

We're going to be giving you part two of three in the burning mountains of I.O.

Because we did do a series of episodes on Jupiter's moons at large

several years back. But I wanted to come back and do a closer pass on Io in particular because

I got visually obsessed with some images produced by the NASA Juno mission in the past year or so.

I guess it's actually a little bit over a year because some of the data that we were looking at was collected in late 2023.

But we talked about several of these images in detail about the strangely polychrome surface of the moon.

And it's truly fascinating surface features, including gigantic blade-like mountains, vast, sulfurous plains, hundreds of erupting
