bars

    When classifying, they ask me if bars of prohibition appear in the center of the galaxy and I do not understand what it refers to, can they explain me?

    Sorry I should have explained better, my question does not refer to the image of the galaxy, it refers to the message when classifying a galaxy

    BAR
    Is there any sign of a bar feature through the center the galaxy?

                     /                                                   X
                 BAR                                          NO BAR

    You can click on the Examples button to see barred galaxies.

    A bar is a straight line of stars on each side of the nucleus, see SBa SBb and SBc

    enter image description hereHere is a picture of a bar in a spiral. Most bars are harder to see than this one.
