# Determining the nature, size and age of the Universe

# Appendix C: Galaxy Information Cards

The information on the cards includes:

-   **Galaxy Name** -- This is one of the names that astronomers use
    when referring to this object. It is by no means the only possible
    name for the object, but may be the most common name.

-   **Other Names** -- These are just a few of the other names used for
    this galaxy. For these information cards, we have limited this
    information to names that are either pronounceable as a word (or
    words), such as the Sombrero Galaxy, or from the following catalogs:

    -   **Messier** -- the Messier catalog is one of the most famous,
        and objects are named with an \'M\' followed by the number of
        the object as counted in the catalog.

    -   **New General Catalogue** -- this is another famous catalogue of
        galaxies. The objects are named with an \'NGC\' followed by the
        number of the object from the catalog.

    -   **Morphological Catalogue of Galaxies** -- this is a less famous
        catalog, at least among non-astronomers, but most of the
        galaxies here are listed in this catalog. The objects are named
        with an \'MCG\' followed by a series of numbers which correspond
        to the way the data was organized for the catalog.

-   **Position** -- The position in the sky given as the Right Ascension
    and Declination. This is one of many ways that astronomers pinpoint
    objects in the sky, but is the most familiar for amateur astronomers
    and optical astronomers.

-   **Redshift** -- This is the measured redshift of light from the
    galaxy, along with the uncertainty in that measurement.

-   **Radial Velocity** -- The measured velocity of the galaxy toward
    (indicated by a minus sign) or away (indicated by a plus sign) from
    us.

The information for these cards was taken from the NASA/IPAC
Extragalactic Database (NED). NED is a database used by professional
astronomers to look up information and articles about extragalactic
sources. We encourage you and your students to look up some of the
galaxies for yourselves in this database at
http://nedwww.ipac.caltech.edu/.
