Scientists have made the first-ever direct measurement of atomic temperatures in extreme materials, shattering a four-decade-old theory about how far solids can be superheated. Using a powerful laser and ultrabright X-rays, researchers at SLAC and collaborating institutions heated gold to an astonishing 19,000 K, more than 14 times its melting point, while it remained solid.
