Did You Know....? - Stars in Their Eyes

The Hubble Telescope has provided evidence that there are about one hundred and seventy five billion galaxies in the observable universe. Despite the prominence of large elliptical and spiral galaxies, most galaxies in the universe appear to be dwarf galaxies. Typical galaxies range from dwarfs with as few as ten million stars up to giants with one trillion stars, all orbiting a common center of mass. The Milky Way contains about two hundred billion stars. Observational data suggests that supermassive black holes may exist at the center of many, if not all, galaxies. The Milky Way galaxy, home of Earth and the solar system, appears to harbor at least one such object within its nucleus.
