The Earth is a mysterious place with the greatest unknowns lying in the oceans, which cover two-thirds of our wonderful world. When you consider the extreme conditions, phenomenal geological features, and eerie creatures that lie kilometers under the sea, your head may begin to hurt a tad. Well, be prepared to have it blown wide open, because when you read about the following breathtaking, awe-inspiring, unfathomable oceans that lie beyond our atmosphere and even our solar system, your brain may well explode.
10The Diamond Oceans Of Neptune And Uranus
At the outer edges of the solar system lie two icy gas giants, Neptune and Uranus, both of which may play host to incredible diamond oceans. Beneath their atmospheres, both planets have similar mantles made up of water, ammonia, and methane ices. Due to their massive weights, their mantles are under a colossal amount of pressure where the temperature ranges between 1,727 degrees Celsius (3,141 °F) and 4,727 degrees Celsius (8,541 °F). It is under these extreme conditions that the methane breaks up into its core components, producing pure carbon, which under immense pressure forms into diamonds.
