Absorption lines are dark lines or bands that appear in the spectrum of a light source due to the absorption of specific wavelengths by a medium, usually gas, through which the light passes. They provide crucial information about the composition, temperature, density, and motion of the intervening medium, making them vital tools in astrophysics and spectroscopy.

Astrophysics is the branch of astronomy that employs the principles of physics and chemistry to understand how stars, planets, and galaxies form, evolve, and interact. It seeks to unravel the mysteries of the universe, from the behavior of subatomic particles in extreme environments to the large-scale structure of the cosmos.
