On this page I collect my observations of the irregular dwarf galaxy NGC 4449 in the constellation Canes Venatici.
The irregular dwarf galaxy NGC 4449 in the constellation Canes Venatici is observed in edge-on position and has a rectangular outline rather than a round or elliptical one. Originally a barred spiral galaxy, it changed its shape due to enormous gravitational forces during an interpenetration, i.e. quasi collision, with the neighboring dwarf galaxy UGC 7577, which took place around 500 million years ago.
