Good evening all... I want to write this article about astronomers who discovered the planet full of diamonds ,called "Lucy" .
The planet is composed of carbon diamond crystal diameter 4.000 kilometers and is located at a distance of 50 light years from Earth (in the constellation Centaurus) .
The scientists believe that diamond is the "heart" of a star  that has been extinct at which time his life before the star was glowing like the sun .
This research was led by Travis Metcalfe (Harvard Smithsonian Center for Astrophysics) .
The maximum size of the diamond on earth is weighing 546 carats was found in the Republic os South Africa , called Africa Star , which used the British royal crown . This amazing :)

Origin of the largest diamond is a diamond weighing 3.100 carats .
Lucy, as known as BPM 37.093 , is actually a white dwarf (white dwarf core) which crystallized .
These findings indicate that the rock is on the whole planet is composed of pure carbon , in the form of purchase of graphite .
However , according to one of the researchers was that if more carbon than oxygen, it will be a lot of rocks that consist of pure carbon such as diamond and graphite and methane gas .
In addition, Lucy has a very close distance to the sun and planets it only lasted a year for 26 hours .
Wew..
But as far what I know of our sun will die in five billion years .
And about two billion years after it will turn into diamonds .
Believe it or not ?
Only God knows the truth :)
Good night all...
Have a nice day .
