Largest laser gives diamond a record-setting squeeze

Diamond has been subjected to the wrath of the world's largest laser, which compressed the stone to greater pressures than it has ever experienced on Earth. The results hint at the mysterious conditions deep inside giant planets.
The dense atmospheres of gas giants Jupiter and Saturn contain carbon. Chemical modelling suggests pressure deep inside the planets would crush it into a rain of diamond chips and perhaps create chunks of diamond large enough to impress even the Kardashians. But until now, no one had been able to replicate such pressures on Earth and test the notion.

Diamond, nature's hardest material, has been crushed to record extremes of pressure using the "world's biggest laser", US scientists report.
The carbon crystal was condensed to the core pressure of Saturn - 14 times that at the centre of the Earth.
The big squeeze was performed inside the US National Ignition Facility, which recently featured in Star Trek.
