Diagram of spiral galaxy

WebAlmost every object in the photo is a galaxy, and these galaxies are at many different distances from us. Is this a photo of a spiral galaxy or an elliptical galaxy, and how do you know? It is a spiral galaxy because we can see a dusty disk going across the center. This photo shows the Large Magellanic cloud, or LMC for short. On the left (in the sense that the sequence is usually drawn) lie the ellipticals. Elliptical galaxies have relatively smooth, featureless light distributions and appear as ellipses in photographic images. They are denoted by the letter E, followed by an integer n representing their degree of ellipticity in the sky. By convention, n is ten times the ellipticity of the galaxy, rounded to the nearest i…
