Topics Covered Include:

• A brief history of astronomy and major discoveries
• The solar system, stars, and constellations
• Modern tools and methods in astronomy
• Electromagnetic waves and telescopic exploration
• Theories of the universe’s origin and development
• Cosmology, theology, and the possibility of life beyond Earth

Students also get hands-on experience observing the night sky and learning key constellations visible in both summer and winter months.

The Classical Nature of Math & Science

Math and science are intrinsically classical disciplines, rooted in logic, order, and the pursuit of truth. When taught in their true form, they harmonize beautifully with the classical tradition, equipping students with tools to think clearly and reason well.
.

A classical approach to science fosters:

• Careful observation and structured thinking
• Deep understanding of principles, not just memorization
• An appreciation of the beauty and order in creation

Astronomy is a prime example of classical learning at the high school level. In the ancient world, it was one of the four core subjects of the quadrivium, the advanced liberal arts, alongside arithmetic, geometry, and music. Far more than stargazing, astronomy was a mathematical and philosophical discipline that revealed the harmony of the cosmos. Over time, this tradition laid the groundwork for what we now call physics.

By studying the cosmos, students step into a tradition that spans centuries of inquiry—one that cultivates wonder, sharpens thinking, and fosters deeper understanding and wisdom. In this way, astronomy helps students meet modern challenges while maintaining intellectual rigor and a sense of meaning.
