Introduction to Astronomy
- Grades 7-11
- CTY-Level
-
Residential
- Science and Engineering
In the 17th century, Galileo looked into the sky with a simple pair of lenses and saw the moons of Jupiter. Modern times have had similarly profound discoveries. This course investigates light, optics, and other areas of physics used in the study of modern astronomy. We’ll tour the universe, learning about planets and their physical, chemical, and geological properties; the mathematics of orbiting bodies; and how to use visual and calculated stellar brightness scales to calculate distances to stars. By plotting sunspots and distinguishing solar types based on color, temperature, and luminosity, we’ll investigate the lifecycle of the sun and other stars; learn about the evolution of galaxies; use data from drifting galaxies to approximate the Hubble Constant; and discuss exotic objects like quasars and black holes.
Typical Class Size: 18-20

About Science and Engineering at CTY
Explore space and our planet
In our Introduction to Astronomy course, we’ll visit a nearby observatory or planetarium, see what the cosmos looks like through various spectra, and immerse ourselves in the science and technology that bring the universe closer to home. In Marine Ecology, we’ll visit local wetlands and tidepools, observe flora and fauna, collect water samples and analyze them for clues about their health and humans’ impact. And in The Global Environment, we will explore the human impact on our environment and generate proposals for addressing climate change.
Bond over chemistry
Our chemistry courses help you see the world differently, starting at the atomic level. The Edible World gives budding chefs and science lovers a glimpse into the chemical reactions that happen when we make food, and the chemical makeup of meals and treats we eat every day. In our Crystals and Polymers course, we’ll synthesize slime, grow rock candy, and isolate strawberry DNA to learn about the molecular structure of naturally occurring gems and human-produced plastics. In Chemistry in Society, we'll consider how the chemicals in products can both enhance and degrade the world around us; produce biodiesel in a lab to understand alternative fuels; and prepare aspirin to learn about the healing and toxic properties of pharmaceuticals.
Meet our instructors and staff
When I was a student at CTY, I was excited to be in a place where all of the instructors and program assistants loved learning as much as I did. It wasn't until I came back as a PA that I realized CTY instructors feel just as excited to work with such dedicated and curious students.

This was my fifth summer working at CTY. I love the culture of CTY. For three weeks, students and staff from all over the world create their own special community unlike anywhere else. I love getting to be a part of that.

CTY is one of the highlights of my year. Even though it’s the summer, the immersive learning in a subject where these students truly excel and shine is invigorating for me as a teacher.
