Extraterrestrial diamonds are found outside Earth's atmosphere, scientist predict that it RAINS DIAMONDS on some planets. Extraterrestrial diamonds are very common in the universe. The heat, pressure and carbon in our universe are enough to form massive diamonds on different planets. Some diamonds are commonly formed on gas giant planets. Such as Saturn and Jupiter. Recently, Scientists found new evidence of diamond rains in Neptune and Uranus .the atmosphere of these ice giants consists of hydrogen and methane. intense lightning converts methane into pure hydrogen and carbon .

This clouds of carbon clump together to form graphite . Extreme pressure on these planets turns graphite into precious diamond . under the effect of gravity diamonds fall to the planet's core . researcher able to create conditions present on these planets in the lab and successfully produced Diamond rain .

it is not the first time that diamonds have been discovered in space . microscopic diamonds not much larger than molecules are abundant in meteorites . diamonds in meteorites form when asteroids collides such collisions crush carbon into diamonds almahata sitta meteorite , which fell into Earth's atmosphere in 2008 . contained fragments that consisted of tiny diamonds tiny , sub millimeter diamonds have been found at meteor crater in Arizona . scientist propose that diamonds exist in carbon-rich stars in the universe .
