Messier 83 (also known as the Southern Pinwheel Galaxy, M83 or NGC 5236) is a barred spiral galaxy[7] approximately 15 million light-years away in the constellation Hydra. It is one of the closest and brightest barred spiral galaxies in the sky, making it visible with binoculars.[8] Six supernovae (SN 1923A, SN 1945B, SN 1950B, SN 1957D, SN 1968L and SN 1983N) have been observed in M83. Its nickname of the Southern Pinwheel derives from its resemblance to the Pinwheel Galaxy.

History[edit]

Nicolas Louis de Lacaille discovered M83 on February 23, 1752 at the Cape of Good Hope.[9] Charles Messier added it to his catalogue of nebulous objects (now known as the Messier Catalogue) in March 1781.[9]

On 16 June 2008 NASA's Galaxy Evolution Explorer project reported finding large numbers of new stars in the outer reaches of the galaxy. It had hitherto been thought that these areas lacked the materials necessary for star formation.[10]

Nearby galaxies and galaxy group information[edit]

M83 is at the center of one of two subgroups within the Centaurus A/M83 Group, a nearby galaxy group.[11] Centaurus A is at the center of the other subgroup. These two groups are sometimes identified as one group[12][13] and sometimes identified as two groups.[14] However, the galaxies around Centaurus A and the galaxies around M83 are physically close to each other, and both subgroups appear not to be moving relative to each other.[15]

Popular culture[edit]

The French synthpop band M83 are named after this galaxy.[16]

The band Clutch makes reference to M83 in their song Spacegrass off their self titled album. "Hey kid, are you going my way? Hop in, we'll have ourselves a field day. We'll find us some spacegrass, Lay low, watch the universe expand. Skyway, permanent Saturday. Oh, by the way, Saturn is my rotary. Hop in, it'll be eternity Till we make it to M83." [17]
