CHICAGO — An entire ocean of liquid magma, or maybe a hot heart of solid metal, may lurk in Io’s underworld.. The surface of Jupiter’s innermost moon is covered in scorching lava lakes and ...

Hot block. Simulations of Yellowstone’s underbelly suggest that the relatively cold remnants of an ancient tectonic plate (blue) block the heat from a rising mantle plume (red) from reaching the ...

The mantle, though not as hot as the earth’s core, is hot enough that some rocks start to melt. This molten rock, called magma, is less dense than the surrounding rocks in the mantle. Due to this ...
