Study Notes
Milky Way Galaxy
- The Milky Way is the galaxy containing our Solar System.
- Its name describes its appearance from Earth – a hazy band of light.
- This band is formed from stars too distant to be seen individually without a telescope.
- The name "Milky Way" is a translation from Latin (via lactea) and Greek (galaxías kýklos), meaning "milky circle".
- The band-like appearance is because Earth is located within the disk of the galaxy.
- Galileo Galilei, using a telescope, resolved the band of light into individual stars in 1610.
- Early astronomers believed the Milky Way contained all the universe's stars.
- The 1920s Great Debate between Harlow Shapley and Heber Curtis, along with Edwin Hubble's observations, proved the Milky Way is just one galaxy among many.
