Using this gigantic underground, water-filled neutrino detector , scientists have finally gotten a better idea of exactly where the Earth's heat comes from: Turns out only half of that heat comes from radioactive decay deep within the planet (which was previously our best guess). The other half may actually be leftover heat from when the Earth and its buddies were formed. It's like Earth is a burning hot ember removed from the fire that forged it, slowly radiating its heat into the vast, cold reaches of outer space.
