M83, also named the "Southern Pinwheel" is experiencing fast rate of star formation with a bar of stars, gas, and dust slicing across the core of the galaxy at different stages of evolution. There are hundreds of young star clusters, ancient groups of globular star clusters, and millions of individual stars (most of them blue supergiants and red supergiants).

The remains of about 60 exploded supernovas, the deaths of massive stars were identified by the Wide Field Camera instaled onboard the Huble Telescope.

According to "www.springerlink.com" on the Book Series "Lecture Notes in Physics", Volume 224/1985, from the book "Supernovae as Distance Indicators":

VLA maps of the galaxy M83 (NGC 5236) at b and 20 cm reveal the presence of both non-thermal and thermal sources, lying predominantly along the inner edges of the optical spiral arms. A radio source coincident with the optical position of supernova 1957d is found to have a non-thermal spectrum; thus SN 1957d is confirmed as the first supernova of intermediate-age (~ 10-300 years) to be detected at any wavelength.
