Diamond is commonly known as one of the hardest materials on Earth – and much of this is down to the way the carbon atoms, which make up the material, are arranged in a lattice structure.
This crystal structure of diamond was the first crystal to be determined by X-ray diffraction – a method that uses X-rays to find out how atoms are arranged in a crystal.
We may not often think about space from the security of our cocoon here on Earth. Some large chunks have already been a little too confining this year, according to NASA’s Center for Near-Earth Object Studies, including the asteroid 1989 JA on May 27, 2001, CB21 on March 4, and 1994 PC1 on January 18.
All of these celestial bodies have a maximum probable expanse of more than 1,000 meters (0.6 miles), and in the case of 1989 JA, it nearly doubles that at 1,800 meters, as asteroid diameters are typically classified as ranges (1.1 miles).
