Giant Earth-sized star made of diamonds discovered

Wisconsin, USA: It is the size of the Earth, around 11 billion years old, and is made entirely from diamond.

The Dwarf Star is the coldest ever detected. And is so cold it has turned into crystallised carbon, making it the biggest bling in the universe.

It has been spotted 900 light-years away on the same pathway to the constellation Aquarius.

University of Wisconsin-Milwaukee’s Professor David Kaplan said: "It really is a remarkable object.

“These things are out there, but because they are so dim, they are very difficult to find.”

Kaplan and his colleagues used the National Radio Astronomy Observatory’s Green Bank Telescope to study the mammoth gem-planet.

White dwarfs are the size of star the size of our sun which are coming to the end of their life and slowly cool and fade over billions of years.

Researchers have worked out the dwarf star would be no more than a comparatively cool 3,000 degrees Kelvin, around 2,700 Celsius.
