Gas Giants like Jupiter barely contain any gas https://twitter.com/SusannaLHarris/status/1289573954588250112">https://twitter.com/SusannaLH...

Their interiors are mostly made of liquid metallic hydrogen and hydrogen above the critical point... so Gas Giant isn& #39;t a really good descriptor. It stems from the fact that they& #39;re made mostly of hydrogen and a tiny bit of helium: these are gases at most temperatures on Earth

People end up thinking we could fly straight through Jupiter.

I left you hanging saying "above the critical point". What it means: if you compress + heat gas it will eventually turn to a state which has the properties of BOTH a liquid and gas. It& #39;s called a supercritical fluid and it dissolves in things like a liquid but moves like gas

Via NASA JPL. You& #39;ll notice there are no diagrams out there which mention the above as it& #39;s complex to explain. Also, we don& #39;t know exactly where all the boundaries are yet. In this diagram they cleverly point to the *edge* of the outer layer, beneath which is supercritical stuff
