There may be millions of carats of diamonds on Neptar and Uatar.

Neptar and Uterin may have millions of carats of diamonds on them, according to a research paper published in the latest issue of the British journal Nature Astronomy.
, which involved several institutions, including the HZDR Research Center in Germany and the University of California, Berkeley, came to this conclusion by simulating the formation of diamonds on the two planets.
researchers used ultra-strong X-rays and lasers to create two shock waves that penetrate polystyrene.
second shock wave is bigger and faster than the first.
When two shock waves are superimposed together, subjecting polystyrene to a huge pressure of about 150 billion Pascals and a high temperature of 5,000 degrees Celsius, the hydrocarbon structure in polystyrene breaks down and almost all of the carbon atoms crystallize into nano-sized diamonds.
researchers likened the process of forming these tiny diamonds to "a diamond rain."
planets like Neptar and Ua once 1000 are made up of a hard core encased in thick "ice".
the main components of the "ice" are hydrocarbons, water and ammonia.
, astrophysicists have long speculated that the enormous pressure inside the planet breaks the hydrocarbon structure, that carbon atoms form diamonds, and that diamonds sink deep into hard cores.
now, the "diamond rain" created in the lab proves the guess.
Although the "diamond rain" lasted less than a second, the researchers can speculate that Nephea and Uayun will form much larger diamonds that will sink to the planet's core over thousands of years.
diamonds on Neptar and Uatar weigh millions of carats, the Times of London reported.
