Interstellar dust

The interstellar dust , or cosmic dust indicates the whole of the particles in the space which are the assembly of a reduced number of molecules in small matter grains. Interstellar dust is distinguished according to their localization; one can specify the term while speaking about interplanetary dust, cometary dust etc They are distinguished also and especially according to their chemical composition (for example aromatic polycyclic hydrocarbons or PAH, carbonaceous grains, silicated grains, grains with coats of ices).
