Neptune and Uranus May Have Oceans of Liquid Diamond

From PopSci:

Future humans won’t have to wait to travel to Pandora for the chance to mine unobtanium, because Neptune and Uranus may have diamond icebergs floating atop liquid diamond seas closer to home. The surprise finding comes from the first detailed measurements of the melting point of diamond, Discovery News reports.

Scientists zapped diamond with a laser at pressures 40 million times greater than the Earth’s atmosphere at sea level, and then slowly reduced both temperature and pressure. They eventually found that diamond behaves like water during freezing and melting, and that chunks of diamond will float in the liquid diamond.

Diamond oceans could explain why the magnetic fields of Uranus and Neptune appear tilted so far off their north-south axes, given that they could deflect or tilt the magnetic fields. Both planets may consist of up to 10 percent carbon, the elemental building block of diamond.

    I think we should send people there to colonize those planets, that way it will feel a little more natural when we go there to take it from them and exploit them.

      That made my day, thanks. :o)

        Anything for you, my dear Chonus.

    Huh. And entire planet that's a shiny bauble.

    now we definately need a woman president. Forget the moon, we'll be on neptune by 2020!!

    Liquid carbon =/= diamond.

    Even if it is full of diamonds, diamonds aren’t -really- very rare or valuable. If DeBiers finds out about this, we’ll have to change the names of the plants. (Aside to Neptune/Uranus, I suggest you hide out with Pluto for a bit.)

Why Is The News Media Comfortable With Lying About Science?

Great question, and it's not only ABC News who screws science up royally. John Timmer writes on ars technica: The year is only a couple of weeks old, but it's...
