What are galaxies made of?

• moons and planets

• two stars orbiting each other

• about one hundred stars

According to the big bang theory, the universe began as an explosion and is still expanding. This theory is supported by observations that the stellar spectra of distant galaxies show a:

• concentration in the green portion of the spectrum

• shift toward the blue end of the spectrum

• shift toward the red end of the spectrum

• concentration in the yellow portion of the spectrum
