The bulge is a spherical structure found in the center of the galaxy. This feature mostly contains older stars. The disk is made up of dust, gas, and younger stars. The disk forms arm structures. s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1421839817 2021-04-15 16:10:29 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1421839817 Our Sun is located in an arm of our galaxy, the Milky Way. The halo of a galaxy is a loose, spherical structure located around the bulge and some of the disk. s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1421842192 2021-04-15 16:10:57 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1421842192 The halo contains old clusters of stars, known as globular clusters. s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1421843606 2021-04-15 16:11:12 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1421843606 s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1421871143 This is a spiral Galaxis]]> 2021-04-15 16:16:09 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1421871143 Irregular galaxies have no regular or symmetrical structure. They are divided into two groups, Irr I and IrrII s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425233775 2021-04-16 13:10:54 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425233775 Irr I type galaxies have HII regions, which are regions of elemental hydrogen gas, and many Population I stars, which are young hot stars. Irr II galaxies simply seem to have large amounts of dust that block most of the light from the stars. All this dust makes is almost impossible to see distinct stars in the galaxy. s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425235686 2021-04-16 13:11:19 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425235686 s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425237115 2021-04-16 13:11:39 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425237115 Elliptical galaxies are shaped like a spheriod, or elongated sphere. s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425246228 2021-04-16 13:13:30 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425246228 The larger the number, the more elliptical the galaxy is. s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425247673 2021-04-16 13:13:50 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425247673 In the sky, where we can only see two of their three dimensions, these galaxies look like elliptical, or oval, shaped disks. s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425249947 2021-04-16 13:14:20 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425249947 s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425253732 2021-04-16 13:15:13 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425253732 All of these Galaxis are in the Universe. s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425259247 2021-04-16 13:16:25 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1425259247 s1811419 https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1426003686 Thanks for waching]]> 2021-04-16 15:49:03 UTC https://padlet.com/s1811419/buayb9348wo3ckgz/wish/1426003686
