Galaxies

Galaxies are large collections of stars, dust, gas and dark matter. The number of stars in a galaxy spans a wide range from millions of stars for a dwarf galaxy to a hundred trillion stars for large elliptical galaxies. Locate and describe galaxies using Wolfram|Alpha. The shape of a given galaxy can be irregular, spiral or elliptical, among others. Galaxies tend to gather in groups, clusters and superclusters. The distribution of galaxies in the observable universe shows a web-like distribution with galaxy clusters and streams bordering on large voids. The Milky Way Galaxy is a barred spiral galaxy while the nearby Andromeda Galaxy is a spiral galaxy without a bar.
