The astrochemistry it is the science that deals with the chemical composition of the Sun and planets, stars and interplanetary diffuse matter or, more generally, interstellar.

Astrochemistry studies the behavior of various types of molecules and free ions in the atmosphere of celestial bodies, and also investigates the formation of the so-called cosmic dust and the relative abundance of chemical elements in the Universe.

For this it uses the spectroscopic analysis of the electromagnetic radiation emitted or absorbed by the celestial bodies.

Astrochemicals rely primarily on radio astronomy and spectroscopy techniques to perform their analysis of interstellar matter, stars and galaxies. Most of the theoretical work in cosmology is dedicated to tracking the evolution of chemical elements from the primitive Big Bang or Big Bang to the death of the stars.
