Absorption Lines
Absorption lines are dark lines that appear in the spectrum of electromagnetic radiation when it passes through a medium that absorbs certain wavelengths. In space and astronautical engineering, absorption lines are used to study the composition and properties of celestial objects such as stars, planets, and galaxies. By analyzing the absorption lines in the spectrum of light emitted by these objects, scientists can determine the chemical elements present in them, their temperature, density, and motion. This information is crucial for understanding the formation and evolution of celestial objects, as well as for designing and operating space-based instruments and telescopes.
