Diamonds under pressure impersonate exoplanet cores
Laser compression may reveal complex physics inside massive alien planets

Researchers have squeezed diamonds to a record-setting pressure — 14 times as high as that inside Earth’s core. The compressed diamond’s properties could reveal the extreme conditions deep inside supersized distant planets, the team reports in the July 17 Nature.
To constrict diamond, the least compressible known material, physicist Ray Smith of Lawrence Livermore National Laboratory in California and colleagues powered up the world’s largest laser, located at the National Ignition Facility (S...
