Under pressure: Researchers compress copper, creating the densest object on Earth

If copper was found in the core of Saturn it would have the same crystalline structure as the copper pipes found in many homes, according to new research from Lawrence Livermore National Laboratory (LLNL) and Johns Hopkins University.

In a paper published today by Physical Review Letters, the research team reveals that copper maintains its crystalline structure at pressures ranging from one atmosphere (room pressure) to more than 30 million atmospheres.

New Research Finds Lead Toughens Up Under Extreme Conditions

In a new paper published as an “Editors’ Suggestion” in Physical Review Letters, a team of researchers from Lawrence Livermore National Laboratory has demonstrated that lead – a metal so soft that it is difficult to machine at ambient conditions – responds similarly to other much stronger metals when rapidly compressed at high pressure.
