Here's a breakdown:
* Outer Layers: The upper layers of Jupiter are indeed gaseous, primarily hydrogen and helium. This is what we see from Earth.
* Deep Interior: As you go deeper into Jupiter, the pressure becomes immense. This pressure compresses the hydrogen and helium so much that they become liquid, creating a vast ocean of liquid hydrogen.
* Rocky Core: Scientists believe there is a solid core at the center of Jupiter, likely made of rock and ice. This core is much smaller than the Earth's core and is surrounded by the liquid hydrogen ocean.
So, Jupiter is more accurately described as a gas giant with a liquid hydrogen ocean and a solid core.
It's important to note that even the "solid" core is likely more like a very dense, fluid mixture under enormous pressure.
