Explain what happens to stars if they have a large mass (size). 3. Find the word nebula. Just to the right of the word is the definition. Please explain what a nebula is. 4. Our sun is called a _____________ ______________ star. 5. About how many years can our sun remain in this stage? 6. What happens when a main sequence star glows? 7. Explain why a RED GIANT star is red. 8. Is our sun a low-mass star or a high-mass star? Explain why it makes a difference. 9. The website explains that all stars begin the same way. It is only after the Red Giant stage that they are different. A low mass star, medium mass star, and a high mass star have different life cycles after this stage. Since our sun is a low mass star, please explain what the next stages for our sun will be. http://imagine.gsfc.nasa.gov/docs/teachers/lifecycles/SC_main_p1.html 10. Describe the life cycle of a medium mass star after the Red Giant stage.
