Astronomy: Explore the Universe, From Planets to Black Holes — the free Preview

This page is the real first concept of Astronomy: Explore the Universe, From Planets to Black Holes (Signature Course No. 384) — not a trailer and not a video. You work through Concept 1, “Distance, Measured Honestly,” in a Socratic conversation with an AI coach: she asks before she teaches, builds on your own answers, and holds you to a mastery bar before the concept counts as done.

What this course teaches. Explore the universe at honest scale: build the solar system to true scale in astronomical units and light-time, read light as evidence, follow stars from birth through black holes to the expanding universe's hot beginning — and close with your own eyes on the real sky. Every figure is stated so you can check it yourself.

How the Preview works. Meet Sutton, our Head Coach, then request your free Preview key — it arrives by email in a moment. Pick your coach (Sutton, Alex, Caroline, Jack, Catherine, or Marcus), hear each one ask this concept’s first question, and begin. One concept, one five-minute conversation, coached exactly as enrolled learners meet it. When you’re ready for all 18 concepts, the full course is $195.
