They have far less structure than spiral galaxies do. Elliptical galaxies are typically found in galaxy clusters.]]> 2022-11-07 16:46:38 UTC https://padlet.com/eliotcoffey1/wkio7k1xje9wzh21/wish/2373449274 eliotcoffey1 https://padlet.com/eliotcoffey1/wkio7k1xje9wzh21/wish/2373449831 A spiral galaxy has a rotating disc with spiral  arms that curve out from its dense central region. For example the Milky Way is a spiral galaxy ]]> 2022-11-07 16:46:53 UTC https://padlet.com/eliotcoffey1/wkio7k1xje9wzh21/wish/2373449831 eliotcoffey1 https://padlet.com/eliotcoffey1/wkio7k1xje9wzh21/wish/2373460946 Irregular galaxies have no particular shape. They are the smallest galaxies and are full of gas and dust. Having a lot of gas and dust means that these galaxies have a lot of star formation going on within them.]]> 2022-11-07 16:53:04 UTC https://padlet.com/eliotcoffey1/wkio7k1xje9wzh21/wish/2373460946 eliotcoffey1 https://padlet.com/eliotcoffey1/wkio7k1xje9wzh21/wish/2373480111 Elliptical - Messier 87

He classified these galaxies further according to the size of their central bulge and the texture of their arms.]]> 2022-11-07 17:08:17 UTC https://padlet.com/eliotcoffey1/wkio7k1xje9wzh21/wish/2373489263
