Earth's Core Far Hotter Than Thought 189

hessian writes "New measurements suggest the Earth's inner core is far hotter than prior experiments suggested, putting it at 6,000C — as hot as the Sun's surface. The solid iron core is actually crystalline, surrounded by liquid. But the temperature at which that crystal can form had been a subject of long-running debate. Experiments outlined in Science used X-rays to probe tiny samples of iron at extraordinary pressures to examine how the iron crystals form and melt."
