Under the heat and pressure that exist inside super-Earths, magnesium oxide and other minerals commonly found in the rocky mantles of the terrestrial planets, transform into liquid metals, laboratory tests show.
The research has implications for understanding conditions on super-Earths, including whether they might be favorable for supporting life.
