1. Snapshot of the Heavens:   The beginning of the chapter likened the problem of studying the  lives of stars to learning about human beings from a 1-minute glance at  human life. What could you learn about human life by looking at a single  snapshot of a large family, including babies, parents, and  grandparents? How is the study of such a snapshot similar to what  scientists do when they study the lives of stars. How is it different?   
2. The Sun and Global Warming:  One of the most Pressing environmental issues on Earth is the Extent  to which human emissions of greenhouse gases are warming our planet.  Some people claim that part or all of the observed warming over the past  century may be due to changes in the Sun rather than to anything humans  have done. Discuss how a better understanding of the Sun might help us  comprehend the threat posed by greenhouse gas emissions. Why is it so  difficult to develop a clear understanding of how the Sun affects  Earth's climate?   
3. The Role of the Sun:  Briefly discuss how the Sun affects us here on Earth. Be sure to  consider not only factors such as its light and warmth, but also how the  study of the sun has led us to new understandings in science and to  technological developments. Overall, how important has solar research  been to our lives?
