molten core
Planetary liquid center
The molten core is the superheated liquid center of a planet, especially Earth's outer core of iron and nickel at temperatures exceeding 4,000°C.
The phrase appears in geology, science fiction, and figuratively for anything with an intensely hot or volatile center: The reactor's molten core breached containment.
Beneath her calm exterior was a molten core of rage.
