Astronomical Naming Conventions - Names of Galaxies

Names of Galaxies

Like stars, most galaxies do not have names. There are a few exceptions such as the Andromeda Galaxy, the Whirlpool Galaxy, and others, but most simply have a catalog number.

In the 19th century, the exact nature of galaxies was not yet understood, and the early catalogs simply grouped together open clusters, globular clusters, nebulas, and galaxies: the Messier catalog has 110 in total. The Andromeda Galaxy is Messier object 31, or M31; the Whirlpool Galaxy is M51. The New General Catalogue (NGC, J. L. E. Dreyer 1888) was much larger and contained nearly 8,000 objects, still mixing galaxies with nebulas and star clusters.

Famous quotes containing the words names of, names and/or galaxies:

    “Tonight there are only the winter stars.
    The sky is no longer a junk-shop,
    Full of javelins and old fire-balls,
    Triangles and the names of girls.”
    —Wallace Stevens (1879–1955)

    “Row after row with strict impunity
    The headstones yield their names to the element,
    The wind whirrs without recollection....”
    —Allen Tate (1899–1979)

    “Don’t you see what’s at stake here? The ultimate aim of all science—to penetrate the unknown. Do you realize we know less about the earth we live on than about the stars and the galaxies of outer space? The greatest mystery is right here, right under our feet.”
    —Walter Reisch (1903–1963)
