Galaxies Galaxies are giant structures that contain hundreds of billions of stars, Oh, by the way…There are billions of galaxies in the universe Galaxies contain single stars, double stars, star systems and lots of gas and dust between the stars. Astronomers classify most galaxies into three main categories: – spiral galaxies, – elliptical galaxies, – irregular galaxies
15
Spiral Galaxies Spiral galaxies have arms that spiral outward, like pinwheels http://zoo1.galaxyzoo.org/images/ tutorial/example_face_on_spiral.jpg http://www.spacetoday.org/images/Hubble/ HubbleBeauty/NGC1512BarredSpiralGalaxy.jpg

The Milky Way Our solar system exists in the Milky Way galaxy, and is about 25,000 light-years away from the center of the Milky Way Our solar system is about two-thirds of the way out on one of the spiral arms of the Milky Way We can’t see the center of the Milky Way due to the massive cloud of gas and dust between the sun and the center

Elliptical Galaxies Elliptical galaxies look like flattened balls Have little gas and dust between the stars so new stars can not form – Ellliptical galaxies only contain old stars http://photojournal.jpl.nasa.gov/ jpegMod/PIA08696_modest.jpg

Irregular Galaxies Some galaxies don’t have a regular shape, they are called irregular galaxies The Large Magellanic Cloud is an irregular galaxy http://www.nasa.gov/images/content/ 159426main_image_feature_666_ys_4.jpg
