Stellar and planetary composition is guessed at by the use of Mass Spectography.

Heat a sample of an element or a compound of the element with a blow-lamp and see what colour the flame turns. When viewed through a prism or series of prisms the colours are separated for analysis.

A similar process is used for radio analysis. A radio frequeny can be seperated by a reciever. Analysis is by comparing the frequencies of various ions.
