Descriptive Astronomy  ·  No Calculus Required

Descriptive Astronomy

Six units. One semester. From naked-eye constellations to black holes and the Big Bang — you'll learn how astronomers know what they know, no equations required, and build a running log of your own observations of the night sky.

From Your Instructor

Welcome to Astronomy

Welcome in. This isn't a physics class in disguise — you won't need to solve for orbital velocity to pass. What you will do is learn to actually look up, recognize what you're seeing, and understand how astronomers pieced together everything from the age of the Sun to the shape of the universe.

We move through a unit a week — the sky itself, the history of how we figured it out, the solar system, stars, galaxies, and cosmology — and you'll keep a running sky journal the whole semester so the class stays connected to the real night sky outside your window.

You don't need a telescope or a math background coming in. Show up, look up, and ask questions — that's the whole deal.

My advice about using AI

This is a class about observing and understanding the real universe, so I use AI to help build it — go ahead and use it too, especially to explore questions that go beyond what we cover in class. The line is between using AI to learn and using it to skip learning.

Bottom line: I can tell when you turn in something you can't explain. That's plagiarism, and it's treated that way — use AI to understand the material, not to avoid it.
