Spectroscopy
Spectroscopy is the study of the interaction between matter and electromagnetic radiation. In the context of space and astronautical engineering, spectroscopy is used to analyze the composition, temperature, and velocity of celestial objects such as stars, planets, and galaxies. Spectroscopy is used to identify the chemical elements present in a celestial object by analyzing the wavelengths of light that are absorbed or emitted by the object. This information can be used to determine the temperature and density of the object, as well as its motion relative to Earth. Spectroscopy is an important tool for astronomers and astrophysicists, as it allows them to study the properties of celestial objects without physically visiting them.
