X-ray Thomson Scattering (IMAGE) Helmholtz-Zentrum Dresden-Rossendorf Caption By using a new measuring method -- the so-called X-ray Thomson scattering -- an international team of researchers was able to prove that the high pressure inside planets like Neptune or Uranus dissolves hydrocarbon into its individual parts and converts the released carbon atoms into diamond structures. Thanks to the new measuring method, such conditions, which experts call warm, dense matter and which do not occur naturally on Earth, can be examined more closely.
