Our cosmos could have “Diamond Rain” worlds!

 

Recommended for Secondary Grades

Research shows that “diamond rain” may happen more often than was thought before. Experts say that the way diamonds fall from the sky is nothing like the way rain falls on Earth.

Scientists think that diamonds could be falling from the sky on planets all over the universe. They believe that thousands of kilometres below the surface of Neptune and Uranus, hydrogen and carbon are turned into solid diamonds by high pressure and temperatures.

What are Nanodiamonds?

Nanodiamonds are extremely small diamonds that are not visible to the naked eye.

Experts think that there is a hot, thick liquid under the surface of each planet. This is where diamonds are made, and then they slowly sink to the rocks at the centre.

Key Facts!

  • Researchers believe that the diamonds that have fallen form layers that are hundreds of kilometres long or even longer.
  • The research team tried to copy the process with PET plastic.
  • This plastic has the right amount of carbon, hydrogen, and oxygen to replicate the process.
  • The group used a very powerful laser to test the plastic.
  • Experts could watch nanodiamonds form as “very, very short flashes of incredible brightness” with the help of an X-ray.
  • The large amounts of oxygen on Neptune and Uranus help to pull the hydrogen atoms away from the carbon, making it easier for diamonds to form.
  • The experiment could give a hint about how to come up with a new way to make nanodiamonds.
  • Nanodiamonds could be used in a number of ways, such as to deliver medicines, or surgery.

Youtube user “What if” has an interesting video on “What if it rains diamonds?”.
