I think the title of the article below is interesting from a science journalism point of view. The direct accomplishment of the study was about the qualities of liquid diamond, a state that is very difficult to achieve. Because of this research, we now know that solid diamonds, like frozen water, are less dense than their liquid counterpart. And the conditions to achieve this are insane (Reminder: They melted a diamond with LASERS!), BUT similar conditions happen to exist on Uranus and Neptune. And based on other studies showing a fair amount of carbon on those planets, the hypothesis that they may have giant diamond oceans and diamond icebergs now has some more evidence supporting it.
Ah, Science!
