-What is the difference between a stellar nebulae and a planetary nebulae? a planetary nebula goes through an average star stage and the red giant stage. The stellar nebulae is at the beginning of the life cycle and a planetary nebulae are more towards the end of the cycle.
-What factor determines the path a star will take in its life cycle? the mass of the star.

-What do scientist use the light from stars for? to determine how far away the star is from the Earth
-What do scientist use radio waves for? to determine what elements are inside of the star.
1/13/11
-Which elements are found in star A? hydrogen and helium.
-Which elements are found in star B? calcium, hydrogen, helium.
-Which elements are found in star C? sodium, hydrogen.
-Which star is more likely the coolest? How do you know? star C because the lines are faded, not very solid/dark. The darker the line, the hotter the star.
