How do we classify galaxies? - We classify galaxies based on if they are spiral, elipitical or irregular. The size is determined be the halo. What kind of stars do elliptical galaxies contain? - Ellipitcal galaxies have only older stars. There is no gas or dust to create new stars. What kind of stars do spiral galaxies contain? - Spiral Galaxies contain old and new stars and much gas and dust. How is the light from active galaxies different from light from normal galaxies? - Active ga...
