5. A type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives.
6. The most common type of star, with masses ranging from 0.08 to 1.4 times that of the Sun. They are relatively small in size, with a diameter of about 0.1 to 0.8 times that of the Sun.

4. These stars are much larger than dwarf stars, with diameters ranging from 10 to 100 times that of the Sun. They are less common than dwarf stars and have much shorter lifespans
7. massive, luminous spheres of plasma that emit light and heat due to the process of nuclear fusion
9. A type of graph that contains information about its temperature, chemical composition, and intrinsic luminosity
