... A billion is 109 or 1,000,000,000. And it is a BIG number! There are many cases in which numbers like a billion are used to describe topics in science, such as the age of the universe, the length of a galaxy, or number of stars in a galaxy. Before we begin to look at our Origins unit, which covers t ...

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.
