Statistical reasoning, measurement uncertainty, and the connection between data and physical models. Learn how astronomers extract meaning from observations.
Not mandatory, but this order builds concepts incrementally.
Key idea: This demo makes the full causal chain legible: Earth moves, line-of-sight changes, and the target star appears to shift against fixed backgr

Key idea: Explore how relative motion shifts spectral lines and why astronomers can measure radial velocity from light alone.

Key idea: Star formation does not make one star at a time. It makes a population, and the distribution of masses in that population — the initial mass

Key idea: Explore why spiral-galaxy rotation curves stay nearly flat at large radius and what that implies about dark matter across scales.
