The star, named “Lucy” after the Beatles song, “Lucy in the Sky with Diamonds,” is estimated to be 2,500 miles across and weighs approximately 10 billion-trillion-trillion-carats – a one, followed by 34 zeros. The largest diamond known to man. Cosmic man….really!
The diamond is actually the crystallized interior of a white dwarf – or the hot core of a star that is left over after the star uses up its nuclear fuel and dies. It is made mostly of carbon and is coated by a thin layer of hydrogen and helium gases.
