Web- There are three basic types of galaxies. -Spiral galaxies do not have much dust in their disks. -Elliptical galaxies do not make new stars. -The halos of spiral galaxies appear reddish, and contain little star formation. -There is no star formation in irregular galaxies. -The nuclei of spiral galaxies appear blue, due to the hot, massive stars. WebThe current theory stands that the galaxies start their lives whether as spiral or irregular galaxies, those galaxies are rich in gas (Hydrogen) and so they can form thousands of millions of stars, so the young galaxies are galaxies whose color is mostly blue.
