Determination of the chemical composition of space objects

written by Lewis Carroll

Determination of the chemical composition of space objects – Space objects studied using electromagnetic radiation spectra make it possible to determine their chemical composition by the presence of radiation or absorption lines in them. The indicators of the energy states of atoms and molecules depend on their chemical nature and physical characteristics. They have the ability to move from one state to another, using energy as certain quanta of electromagnetic radiation, which are peculiar to a certain chemical substance. This is due to the fact that each chemical element leaves its own “autograph” in the spectrum – dark or light lines and stripes that are located in strictly defined places.
