      Apparently liquid nitrogen can be ‘easily converted to the solid by placing it in a vacuum chamber pumped by a rotary vacuum pump’ However, this requires lowering the temperature to −210 °C, so not easy for you or I to do!

      Under very very high pressure and temperature it can form a solid with a similar structure to that of a diamond.

      These states do not occur naturally on Earth with humans creating them, but elsewhere in the universe it is likely that nitrogen can exist in these forms
