Keywords:Interstellar Medium, Dust grains, interstellar extinction, dust models
AbstractThe Interstellar Medium- the medium between the stars is an active and dynamic medium and is a region of potential activity. Probing the ISM is interesting in itself. Understanding the gas and grains of the ISM provides vital clues on the evolution of the universe and our galaxy. The birth and death of stars takes place in the ISM. Spectral absorption features provide a wealth of information on the nature and composition of grains.
