Study Notes
Astronomical Observations Before Telescopes
- Early astronomers observed the sun, moon, and stars
- They tracked the sun's rising and setting, and yearly variations
- They noted phases of the moon and lunar/solar eclipses
- They observed the daily and annual movement of stars and constellations
- They identified and documented planets (Mercury, Venus, Mars, Jupiter, and Saturn)
Earliest Astronomical Observations
- Nebra sky disk (c. 1600 BC): Bronze disk showing celestial objects, possibly a religious/astronomical calendar
- Native American rock drawings: Similar representations of the sky
- Early rock drawings: Petroglyph showing a supernova (1006 AD) related to the Crab Nebula
- Babylonian records (c. 1600 BC): Earliest written astronomical observations, documenting planetary positions and eclipses
- Stonehenge, Chinese, and other cultures also recorded astronomical events
Hellenistic Observations
- Thales (480 BC): Used Babylonian eclipse data to predict eclipses, an influential Greek philosopher
- Eratosthenes (250 BC): Calculated Earth's circumference, used geometry and a spherical Earth model.
- Aristarchus (270 BC): Proposed the heliocentric model (Sun-centered solar system)
- Plato: Introduced planets following perfect circular orbits around Earth (geocentric model)
- Heraclides (330 BC): Presented an early geocentric model of the solar system.
Renaissance and Astronomical Observations
- Copernicus (1500): Reintroduced the heliocentric model, challenging the Church's geocentric view
- Tycho Brahe (1580): First significant astronomical observer, founded the Danish Observatory, and accurately measured planetary and star positions
- Kepler (1600): Student of Brahe, utilized Brahe's data to formulate the laws of planetary motion (elliptical orbits)
- Galileo Galilei (1620s): Pioneered astronomical observation, created the first practical refracting telescope, impacting existing astronomical beliefs.
