As the protogalaxy continues to spin, smaller eddies, or small density fluctuations, of concentrated gases, dust, and matter can form in different parts of the galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence , and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure. They have a bulge and halo, like spiral galaxies, but don't have the flat disk of stars. 2 Is our galaxy spiral elliptical or irregular? In a telescope, a globular cluster looks like a fuzzy ball, with individual stars at the periphery merging into a solid ball of light towards the center. There are four distinguishing characteristics of the ellipticals: (a) they have much more random star motion than orderly rotational motion (star orbits are aligned in a wide range of angles and have a wide range of eccentricities); (b) they have very little dust and gas left between the stars; (c) this means that they .
