Stars, which are (4) ____ of gas (mostly the gases hydrogen and helium) emit radiation. They create energy by fusing hydrogen and turning (5) ____ into helium in their cores. We see the resulting energy as (6) ____.

Astronomers classify star (7) ____ their size, temperature, color, and luminosity. Size in this case relates to mass rather than liner measurement, such as diameter. Stars start the same way, but (8) ____ lives play out according to their (9) ____ and mass. The mass of a star determines all of its other (10) ____ including how hot is it, what color it is, and how long it will live. Massive stars are hot and blue, whereas small stars are cool and red.
