NGC 1300, viewed nearly face-on; Hubble Space Telescope image. A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. [1] Bars are found in about two thirds of all spiral galaxies in the local universe, [2] and generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well.
A spiral galaxy is a type of galaxy characterized by a central bulge of old Population II stars surrounded by a rotating disc of younger Population I stars. A spiral galaxy maintains its spiral arms due to density wave theory.

It is part of the NGC 2217 Group of galaxies. It is classified as a barred spiral galaxy. A notable feature is the swirling shape of this galaxy. In its very concentrated central region we can see a distinctive, very luminous bar of stars within an oval ring. Further out, a set of tightly wound spiral arms almost form a circular ring around the ...
Barred spiral galaxy UGC 12158. Spiral arms are regions of stars that extend from the center of barred and unbarred spiral galaxies. These long, thin regions resemble a spiral and thus give spiral galaxies their name. Naturally, different classifications of spiral galaxies have distinct arm-structures. Sc and SBc galaxies, for instance, have ...
NGC 1365, also known as the Fornax Propeller Galaxy [2] or the Great Barred Spiral Galaxy, [3] is a double-barred spiral galaxy about 56 million light-years away [4] in the constellation Fornax. It was discovered on 2 September 1826 by Scottish astronomer James Dunlop .
NGC 6872, also known as the Condor Galaxy, [3] is a large barred spiral galaxy of type SB(s)b pec in the constellation Pavo. It is 212 million light-years (65 Mpc ) from Earth. [ 3 ] NGC 6872 is interacting with the lenticular galaxy IC 4970 , which is less than one twelfth as large.
