A total eclipse is one of the most spectacular sights you can ever see! It looks like the end of the world may be at hand. There is a black hole in the sky where the sun should be. Pink flames of solar prominences and long silver streamers of the sun's corona stretch across the sky. It gets cold, and animals do strange things. People scream and shout and cheer, and remember the experience their whole life. But total eclipses are important scientifically as well. They let us see parts of the sun’s atmosphere that are otherwise invisible. A total eclipse presented the first chance to test Einstein’s prediction that matter can bend space – like near a black hole. The best total eclipse in the United States in 40 years happens August 21st, 2017.

Excellent information for a brief overview of the eclipse and the science behind it!
I learned a lot and wished I'd known how interested I am in physics. Looking forward to August 21, 2017. Thanks Dr. Doug for your teaching!
Good Knowledgeable course for all the students. This course has increased my knowledge about the solar system and earth.
Very interesting course about the Sun. In the title it is mentionned 2017, but it is applicable for all other eclipses.
