Astronomers have actually found a diamond in the sky - directly above Australia.
Confirming what the Beatles always knew, astronomers have actually found a diamond in the sky - directly above Australia. It is the biggest known diamond in the universe, in fact. According to American astronomers at the Harvard-Smithsonian Centre for Astrophysics, a white dwarf star in the constellation of Centaurus, next to the Southern Cross, has been found to have a 3000-kilometre-wide core of crystallised carbon, or diamond. It weighs 2.27 thousand trillion trillion tonnes - that's 10 billion trillion trillion carats, or a 1 followed by 34 zeroes. The biggest earthly jewel is one of the British crown jewels, the 530-carat Star of Africa. However, this cosmic jewel is hidden beneath a layer of hydrogen and helium gases, with the diamond core making up between 50 and 90 per cent of its mass, informs TheAge.com.au The biggest ever diamond has been found floating in space. The gem, estimated at close to 10 billion trillion trillion carats, is at the core of a dead star (BPM 37093) - a crystallised white dwarf. The newly-discovered diamond in the sky is a whopping great chunk of crystallised carbon 50 light-years from the Earth in the constellation Centaurus. It is 2,500 miles across (the moon is approximately 2,200 miles across) and weighs 5 million trillion trillion pounds. It has been dubbed "Lucy" in reference to the Beatles' song, "Lucy in the Sky with Diamonds". Diamond specialists told the research team that if nothing else, the diamond was much too big to wear, reports TheRegister.co.uk According to ThisIsLondon.co.uk American astrophysicists spotted the diamond 50 light years away in the constellation Centauru on Valentine's Day. "It's the mother of all diamonds," said Travis Metcalfe, head researcher at the Harvard-Smithsonian Centre for Astrophysics. " You would need a jeweller's loupe the size of the Sun to grade it." The stars formed from a massive cloud of gas and dust that contains enough raw materials to create 1,000 sun-like stars. Fragments of the cloud became so cold and dense that they collapsed into stars. Most stars in our Milky Way galaxy are thought to form in such clusters
