New simulations suggest Jupiter holds far more water than once thought, reshaping ideas about how the largest planet formed.

"We used to think that only very simple molecules could be created in these clouds. But we have shown that this is clearly ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

The solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...
