   NGC 4449 is an irregular galaxy located about 12 million light years away in the constellation Canes Venatici. Young blue stars approximately 5 million years old extend in a bar shape across the central part of the galaxy structure. The galaxy size and structure is similar to the Large Magellanic Cloud near our own galaxy. Glowing H II regions show where active star formations are occurring. Some theories for the active star activity are a possible merger or interaction with other neighboring galaxies.
