There are a few theories that would suggest Jupiter’s moon IO has an underground magma ocean. Hank Green explains in this episode of SciShow Space!

Looking for SciShow elsewhere on the internet?
I really like the video of that volcano erupting what a sight! its very amazing how a moon is capable of such volcanic activity! thanks for the vid sci show!
9th planet hype begins!
What exactly is the difference between a magma ocean and a mantle? They seem like two labels for the same thing to me.
SciShow Space What is the speed of Gravity???
Make a video about that
So I can find aliens riding io Hawks on io?
To me Io looks really nasty
You guys MUST do a video on the (possible) 9th planet!
Where does all the kinetic energy come from? If the orbit and tidal forces Jupiter has on the moon can heat up it's insides, where does the kinetic energy come from?
9th planet hype
Well, it looks like your next episode's got to be about Planetnine!
I like that shirt
Is there a video about "Planet Nine" in the works?
Dying to know what that's all about
io looks moldy
toppings like mold….
Sometimes I am amazed at how much we know about about stars unimaginably distant, but don't know the rotation speed of an object in our own solar system. Unless the speed isn't constant due to all that shape-changing and such, why would we not know Io's rotation speed?
I never understood the movie 2001: A Space Odyssey
What's the difference between a magma ocean and a mantle? Seems like those are the same to me
Could it be, that with the constant gravitational pull on Io, the volcanos errupt at the 30/60 degree angle because the planet is being stretched into an oval shape by Jupiter, Europa and Ganymede?
It only seems logical that the volcanoes errupt in these angles because that's the part of the surface which is being stretched (due to structural weaknesses in the crust formed because of these gravitational pulls)
How is geographical directions determined on other planets? Hank said that the volcanoes were shifted further east, but what is 'east' on other planets? Is it by rotation, and if so does it change anything if the planet/moon is found to have a magnetic core? what if it rotates in funny ways or is tidally locked?
IO surface looks like a potato
Europa, Enceladus, Ganymede, Calisto and now Io? What is it with all these moons having subsurface oceans of some kind?
0:08 SciShow I like your videos, but io doesn't look like a "Pizza". I mean common. it's obviously a blue-red spaghetti square with rainbow lazered banana cats all over its face.
Or they could be eruptions of electrically charged particles similar to those seen on most comets, in particular on 67P.
Looks more like a Petri dish than pizza to me
