Alien lifeforms ‘evolved on priceless planet made of precious stone’
Stargazer says the first living beings in our universe developed on mysterious 'diamond worlds' orbiting primitive and ancient stars
They are the diamonds which are much bigger than the Ritz and as valuable to scientists as they are to jewellers.
Astronomers have claimed early lifeforms may have evolved on mysterious worlds made entirely of carbon - the chemical which forms humanity's most prized precious stone.
These priceless planets are likely to have formed billions of years ago in the early universe and may have been incubators for ancient alien life.
"We have good reason to believe that alien life will be carbon-based, like life on Earth, so this also bodes well for the possibility of life in the early universe," said Natalie Mashian of Harvard University.
In a paper published in the , she called on astronomers to begin looking for carbon planets in the hope of "shedding light on the question of how early planetary systems may have formed after the Big Bang".
She said diamond worlds may have formed before space had been "seeded" with the chemicals which produced planets like our own.
