Messier 83 or M83, also known as NGC 5236, is a barred spiral galaxy approximately 15 million light-years away in the constellation borders of Hydra and Centaurus. Nicolas Louis de Lacaille discovered M83 on February 23, 1752, at the Cape of Good. Charles Messier added it to his catalog of nebulous objects (now known as the Messier Catalogue) in March 1781. It is one of the closest and brightest barred spiral galaxies in the sky and is visible with binoculars. Its nickname the Southern Pinwheel derives from its resemblance to the Pinwheel Galaxy (M101) in the northern constellation Ursa Major.
Starbase image set "M83 - Lum (2021): Southern Pinwheel Galaxy" has over 10 hours of Luminance image data and set "M83 - RGB (2021): Southern Pinwheel Galaxy" consists of 3 hours each of Red, Green, and Blue image data.

NGC 1313 is a field galaxy and a barred spiral galaxy discovered by the Scottish astronomer James Dunlop on 27 September 1826. It has a diameter of about 50,000 light-years or about half the size of the Milky Way. NGC 1313 lies within the Virgo Supercluster. NGC 1313 has a strikingly uneven shape and its axis of rotation is not exactly in its center. The galaxy also shows strong starburst activity and associated super-shells. NGC 1313 is dominated by scattered patches of intense star formation, which gives the galaxy a rather ragged appearance. The uneven shape, the ragged appearance, and the strong starburst can all be explained by a galactic collision in the past. However, NGC 1313 seems to be an isolated galaxy and has no direct neighbors. Therefore, it is not clear whether it has swallowed a small companion in its past.
