... What are sunspots? Why do they appear dark in pictures of the Sun? Sunspots are dark patches on the Solar photosphere that mark regions where the magnetic field is strong. They are dark because the sunspot is cooler than the rest of the photosphere. Cool gases emit less thermal radiation than hot ga ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
