10 Facts about Elliptical Galaxies
Facts about Elliptical Galaxies elaborate a type of galaxy, which has featureless image and ellipsoidal shape. It does not have much structure. However, this galaxy has a three dimensional shape. The elliptical galaxy is very different from the flat spiral galaxies for the latter features structure and organization. The stars found on the elliptical galaxies sit on the random orbits. Have you ever heard about Edwin Hubble? This scientist was the one who described three galaxies. Elliptical galaxy was one of them.
