Module 1 Synthesis
Foundations — Putting It All Together
Welcome to Module 1 Synthesis
You’ve completed 13 lectures covering the astronomer’s toolkit. These synthesis materials help you consolidate that learning, see connections between concepts, and prepare for assessment.
Given only light from a distant object, you can now determine:
- Distances — from parallax, standard candles, or Kepler’s Third Law
- Masses — from orbital motion (Newton’s version of Kepler’s Third Law)
- Temperatures — from peak wavelength (Wien’s Law) or total brightness (Stefan-Boltzmann)
- Compositions — from spectral absorption/emission lines
- Motions — from Doppler shifts of spectral lines
This is not memorization. This is the actual toolkit professional astronomers use.
