En résumé

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 US in 40 years happens Aug. 21, 2017. This course will prepare you to see it, to help people watch safely and even make money by leading a “neighborhood watch” of the eclipse, and to learn about the sun: how astronomers study it, how it formed, and how we know what’s inside it where the energy that supports life on earth is generated.

Le programme

  • Week 1 - Introduction to the Sun and Eclipses
    In this module we describe what causes eclipses, how rare it is for any one place to experience a total eclipse, the dramatic difference between a total or a partial eclipse, and encourage you to see the total eclipse on Aug. 21, 2017. We also review the upco...
  • Week 2 - Most of what we know about the Sun is learned from Light
    In this module we explain how astronomers use visible and invisible light (ultraviolet and X-rays) to study the sun. We learn that all light comes from atoms, and that the quantum world of atoms is like nothing you’ve ever seen! We see how the properties of li...
  • Week 3 - How does the Sun work? What makes it shine? What’s inside?
    We can’t see inside the sun with visible light, but there are ways to infer or even see down to the sun’s center, where vast amount of energy are generated, making possible life on earth.
  • Week 4 - How did the sun form?
    When you look at Hubble Space Telescope images of beautiful clouds of gas in space you are seeing what happened in our own solar system 4 ½ billion years ago when the sun formed. This week we explain how that process works.
  • Week 5 - The Aug. 21, 2017 “Great American Total Solar Eclipse”
    This Week 5 presentation concentrates on what will happen during the Great American Eclipse of Aug. 21, 2017. It may be viewed alone, or after Weeks 1-4. Weeks 1-4 give a lot of explanation of what you will see, so I hope you take the full course, but if you...
