Interstellar Medium (ISM): The matter and radiation that exist in the space between the star systems of a galaxy.
Light Scattering: The deflection of light by particles or irregularities in a medium, dependent on particle size and wavelength.
Spectral Type: A classification of stars based on their temperature and spectral characteristics, indicated by letters like O, B, A, F, G, K, M.
Stellar Nursery: A region in space where new stars are being formed from interstellar gas and dust.
