Why are galaxies different colors?
Lydia AllenGalaxies are huge groups of stars and space gas and dust,
Stars have temperature varying fro m 3000 to 40000 degree on their surface..So naturally Galaxies show the color of stars.

John AlexanderGalaxies appear different colors due to the variation in the types and ages of stars within them, as well as the presence of dust and gas. Young, hot stars emit blue light, while older stars emit red light. Dust and gas can also absorb and scatter light, affecting the overall color of a galaxy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
