As telescopes become more powerful and techniques for detecting distant exoplanets become more sophisticated, astronomers continue to discover strange and bizarre worlds that seem like something out of science fiction. There are planets with iron rain or with yellow skies, those shaped like a football or where a year lasts just a week.
Now, in a concept straight out of a dream, new research shows that our universe could host planets made of diamonds.
Researchers at Arizona State University looked at a specific type of planet which is high in carbon. Most planets are formed from the same cloud of gas which formed their stars, and therefore have similar composition. So you end up with planets like Earth which has a low ratio of carbon to oxygen, making diamonds (which are composed of carbon) a relative rarity.
But other planets form around stars with different compositions, where the ratio of
