Neptune and Uranus are called as the most mysterious places in the solar system.For the first time, scientists were capable of observing the diamond raining made by the higher pressure, which leads to squeeze the hydrogen and carbon inside the planets Uranus and Neptune to form diamonds.
The scientists from SLAC National Accelerator Laboratory of Stanford University in California used a ‘Linac Coherent Light Source’ to create the world’s brightest X-rays. The waves of shock in plastic with an optical laser in the instrument‘Matter in Extreme Condition (MEC)’, created an extreme high pressure on carbon and hydrogen for the formation of ‘diamond rain’ in deep inside the Uranus and Neptune.
Dominic Karus, a scientist from Helmholtz Zentrum Dresen Rossendorf and also the author of Gizmodo, said that, “This condition will generate diamonds precipitation inside the celestial bodies. This means that there is not necessarily a pure diamond core but certainly a large diamond envelope around the rocky cores that are supposed to exist inside Neptune and Uranus”.
The tool Matter in Extreme Condition helped scientists to shock a thin sheet of polystyrene with laser blasting to produce a pressure over 150 gigapascals below 8000km of surface of the planets Uranus and Neptune. Since, the materials was heated off nearly 6000 Kelvin, which does not let the diamonds to melt but it breaks them into small parts called ‘Nano diamonds’.
Karus added that, “If the temperature is high enough close to the core it could also be ‘oceans of liquid carbon’ with gigantic ‘diamond icebergs, swimming on top of it, but most theories suggest that diamond would remain solid, at least inside Neptune and Uranus, but this may be different for some exo-planets.”
