  • Interesting fact: There are over one hundred billion galaxies with each galaxy having billions of stars
    • Galaxy A splendid or impressive assemblage of persons or things; as, a galaxy of movie stars.
    • Galaxy A very large collection of stars comparable in size to the Milky Way system, held together by gravitational force and separated from other such star systems by large distances of mostly empty space. Galaxies vary widely in shape and size, the most common nearby galaxies being over 70,000 light years in diameter and separated from each other by even larger distances. The number of stars in one galaxy varies, and may extend into the hundreds of billions.
    • Galaxy The Milky Way, that luminous tract, or belt, which is seen at night stretching across the heavens, and which is composed of innumerable stars, so distant and blended as to be distinguishable only with the telescope.

  • Interesting fact: A galactic year is 250 million Earth-years. This is the time it takes for our solar system to make one revolution around the Milky Way Galaxy.
    • n galaxy In astronomy, the Milky Way, a luminous band extending around the heavens. It is produced by myriads of stars, into which it is resolved by the telescope. It divides into two great branches, which remain apart for a distance of 150° and then reunite; there are also many smaller branches. At one point it spreads out very widely, exhibiting a fan-like expanse of interlacing branches nearly 20° broad; this terminates abruptly and leaves a kind of gap. At several points are seen dark spots in the midst of some of the brightest portions.
    • n galaxy Hence—2. Any assemblage of splendid, illustrious, or beautiful persons or things.
    • n galaxy Same as galax, 2: a play upon that name.

Where stars were very small indeed,
