 Astronomical spectroscopy

Astronomical spectroscopy is a technique used in astronomy to analyze the light emitted, absorbed, or scattered by objects in space, such as stars, galaxies, and nebulae. It involves breaking down this light into its constituent wavelengths, creating a spectrum that reveals a wealth of information about the source of the light. Key aspects of astronomical spectroscopy include: 1. **Spectra Types**: The resulting spectrum can be continuous, emission, or absorption spectra, each providing different insights.
