A planet made entirely of diamond was newly discovered orbiting around a tiny star, lying around 4,000 light years away from Earth in the constellation Serpens.
A team of astronomers from Australia, Germany, Italy, the UK and the U.S. discovered the exotic diamond planet during their search for a pulsar, using the Parkes 64-meter radio telescope in western New South Wales.
The diamond planet is estimated as 34 thousand 175 miles across, which is about five times Earth's diameter.
As the planet largely consists of carbon, scientists speculate that the carbon within it has the right conditions to be crystallized, and believe it to be completely made of diamond.
That would make it the universe's largest diamond of 1031 carats worth.
