- The band's appearance is due to Earth's position within the galaxy's disk-shaped structure.
- Galileo Galilei, in 1610, used a telescope to resolve the band into individual stars.
- Until the 1920s, many astronomers believed the Milky Way encompassed all the universe's stars.
- The 1920 Great Debate, involving Harlow Shapley and Heber Curtis, was pivotal.
