Star Trek Nebula Classification

English Abstract: 

"A nebula is an interstellar cloud of dust, gas, and plasma, where star formation usually occurs. In the year 2400, the Federation introduced a new system to classify nebulae. The new system first assigns the nebula a letter designation based upon its general composition. If the nebula has any unusual quirks, it is assigned an additional number designation. For example, a Class F2 Nebula is a Dark Nebula that contains disruptive electromagnetic radiation."
