It is thought that the distorted structure of NGC2442 arose from an interaction with a dwarf galaxy in the same group.  Star forming regions are prevalent throughout the arms, but are concentrated in the northern spiral arm and tend to avoid the bar.  The nucleus is rapidly rotating.  This galaxy is not experiencing strong starburst.  This galaxy was a commissioning target of the Spitzer Space Telescope.
