Spectroscopy in Astronomy
One of the ways that modern telescopes observe the sky is by using spectroscopy to measure the brightness of an object in separate colors or wavelengths. Spectra of objects can reveal chemical composition, temperature and density. Spectral observations can also learn about the material between us and distant objects.
