A total eclipse is not only exciting but important scientifically as well. It lets us see parts of the sun’s atmosphere that are otherwise invisible. Einstein’s prediction that matter can bend space – like near a black hole – was tested for the first time during a total eclipse. 

This online astronomy course explores the science of the sun and the physics of light. You will explore the total eclipse that occurred on August 21, 2017.

By completing this course, you will be able to:

  • Safely view a total or partial solar eclipse
  • Help others watch safely
  • Review fundamental sun science, including the physics of light, how astronomers study the sun, how it formed, how we know what’s inside it, and where the energy that supports life on earth is generated
