Space Diamonds Real and Strong
Reading Time: 2 minutes

Space diamonds are real and strong, created by an interstellar collision of a dwarf planet and an asteroid. This makes them super hard and can be used in tools and production, according to the researchers.

Scientists report  Proceedings of the National Academy of Sciences stated to have found rare lonsdaleite diamonds inside ureilite meteorites and likely originate from the innermost core of a dwarf planet.

Lonsdaleite is a substance that is potentially stronger than traditional diamonds. This makes it ideal to use in the production of more durable industrial machine parts for mining and other industries, according to Colin MacRae, a scientist with Commonwealth Scientific and Industrial Research Organization (CSIRO) in Canberra, Australia.

In case of regular diamonds the carbon atoms are arranged in a cubic shape, whereas in lonsdaleite they are arranged in hexagons.

CSIRO website mentioned, “If something that’s harder than diamond can be manufactured readily, that’s something (industries) would want to know about.”

What are Space Diamonds?
Lonsdaleite, was named after British scientist Dame Kathleen Lonsdale, the first woman to be elected to the Royal Society of London in 1945. Recently, an Australian and U.K. research team analyzed meteorite samples and found graphite, diamond and lonsdaleite.

According to Dougal McCulloch, director of the RMIT University Microscopy and Microanalysis facility in Melbourne, Australia, “This study proves categorically that lonsdaleite exists in nature.”

The researchers estimate that the substance formed about 4.5 billion years ago when an asteroid collided with a dwarf planet in our solar system. Lonsdaleite and traditional diamonds were created from existing carbon from the impact of the asteroid.

Recently, scientists have found a new way for lonsdaleite and diamond to form. Scientists believe this process was caused by a catastrophic collision in the dwarf planet shortly after it.

Size of These Diamonds

Crystal McCulloch said the largest Lonsdaleite crystals discovered were a micron in size. They are much thinner than human hair.

Still, these findings are small and could be significant in the future since this process is already used to produce diamonds in a lab setting and could be in use for industrial purposes.

Nature has provided us with a process to try and replicate in industry.

He mentioned that lonsdaleite could be used in the future to make tiny, ultra-hard machine parts.
