Andromeda Galaxy, also known as M 31, with two dwarf satellite galaxies. As the nearest spiral galaxy to our own, Andromeda has often been suggested as a lookalike for the Milky Way. Recent investigations indicate that it is also a barred spiral. Courtesy NASA/JPL-Caltech.

NGC 1300 in Eridanus, whose central region appears in a widely published photograph by the Hubble Space Telescope. This large galaxy presents its two-armed barred spiral structure in a face-on orientation; each arm extends out of the frame in long streams of stars, dust, and gas. Courtesy NASA/HST/ESA.

This wider-field view of NGC 1300 gives a better picture of its tightly wrapped spiral arms, further highlighting this galaxy's potential resemblance to the Milky Way. Copyright R. Jay GaBany/Cosmotography
