4. Irregular Galaxies Irregular galaxies have no regular or symmetrical structure. They have regions of elemental hydrogen gas, and many young stars. They have large amounts of dusts from which stars are born. No Excuses, Just Results! Show-up, Engage & Produce
9. Spiral Galaxies Spiral galaxies have three main components: a central bulge, disk, and halo No Excuses, Just Results! Show-up, Engage & Produce
10. Spiral Galaxies The bulge is a spherical structure found in the center of the galaxy. This feature mostly contains older stars. No Excuses, Just Results! Show-up, Engage & Produce
11. Spiral Galaxies The disk is made up of dust, gas, and younger stars. The disk forms arm structures. Our Sun is located in an arm of our galaxy, the Milky Way. No Excuses, Just Results! Show-up, Engage & Produce
12. Spiral Galaxies The halo of a galaxy is a loose, spherical structure located around the bulge and some of the disk. The halo contains old clusters of stars, known as globular clusters. No Excuses, Just Results! Show-up, Engage & Produce
13. Spiral Galaxies Globular clusters are spherical concentrations of stars typically 100 light years across and containing thousands of stars. Globular clusters 10 billion years old formed when the galaxy was still forming. No Excuses, Just Results! Show-up, Engage & Produce
18. Elliptical Galaxies Elliptical galaxies are shaped like an elongated sphere. The light is smooth The surface brightness decreases as you go farther out from the center. Elliptical galaxies have no particular axis of rotation. No Excuses, Just Results! Show-up, Engage & Produce
