Intro to the Night Sky - AST 114, Astronomy Lab II for Spring 2017!

Stars also appear in different colors. Astronomers occasionally use an archaic method of specifying the brightness of an object. This ...

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.
