Bruno & Galileo
Bruno: burned at the stake, in part for advocacy of heliocentric theory
Galileo: Builds a telescope
- Craters, mountains and “seas” on the moon: Not a prefect circle, a world like earth
- Milky way is made of stars.
- Sunspots: The sun is not perfect
- Venus has phases: Supports heliocentrism.
- Jupiter has moons: Mini solar system.
