This beautiful galaxy, is difficult to classify. While its physical properties - such as mass, size and rotational velocity - indicate it to be a spiral galaxy, its appearance looks more like a comet with its dense, luminous "head" and dimmer "tail" trailing off. Features more fitting with a dwarf irregular galaxy. New stars are springing into life within the bright, colorful 'head' of this galaxy and ejecting streams of high-speed particles as they do so, which flood outwards to join the wider galactic wind. While this galaxy would be a perfect candidate to study such winds, recent studies did not find any galactic winds in it.
