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 upcoming course topics, demonstrate how large the sun is, and introduce sunspots. ...

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 light let us determine the sun’s temperature, its composition, and the important role of its magnetic fields....

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. ...

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....
