Diamond Seas?

January 27, 2010

How awesome would that be?  Whole seas of diamonds swirling and flashing in the light…I can picture it and it is beautiful.  So what gave me this idea, you ask?

Well, my son is doing a research project on a space topic and he picked Uranus.  My husband jumped on the bandwagon and looked around on the web to help him find some interesting articles, and he found this one on Discovery News.

Apparently, both Uranus and Neptune have a magnetic north that is significantly off geographic north.  The theory is that, due to the high temperatures and pressures and the abundance of carbon on both planets, there may be seas of liquid diamond on the planets.  Scientists recently created conditions similar to what they believe exist on these planets in a lab and found that they could in fact liquify diamond, and surprisingly enough, when they did so the liquid diamond had similar properties to water.  Water is one of the few substances that is more dense in its liquid form than its solid form, which is why ice floats.  According to these experiments, diamond is the same way – as the scientists reduced the pressure on the liquid diamond and solids started to form, they floated.  So in the diamond seas that are becoming more and more plausible on Neptune and Uranus, there could even be diamond icebergs!

Now we just need to send spaceships to Neptune and Uranus to see if we’re right.  If so, I want a diamond iceberg!
