For two decades, scientists have debated the details of the core’s temperature. Knowing its temperature is key to understanding the Earth’s internal processes, particularly its magnetic field and its geothermal activity.

Now a research team, led by Simone Anzellini of the French national technological research organization CEA, has built an experiment that moved this elusive subject into the lab, re-creating the conditions at the center of the Earth.
