The most common occurrences of this phenomena take place at higher northern and southern latitudes, less frequent at mid-latitudes, and are almost never seen near the equator. AurorasContinue reading “The Aurora”
The Importance of Spectroscopy
The impact that spectroscopy and light has had on the world has not been recognized enough. The discovery of spectroscopy has allowed us to know so much more about astronomy and what makes up our universe. Spectroscopy is the investigation and measurement of spectra when matter interacts with electromagnetic radiation. In astronomy, we look atContinue reading “The Importance of Spectroscopy”
