Detailed Information:
M63 is a spiral galaxy, but with a twist. This spiral has lost cohesion in its arms and they are gradually being whirled into space. The inner portion of M63 is well formed, however the numerous outer arms are loose and patchy and disorganized. This gives rise to the nickname, The Sunflower Galaxy, because these arms surrounding the tight center resembles the dense, overlapping petals of the sunflower.

M63 was first observed by M.Méchain on 14 June 1779 and is best observed visually under low power. While it is located within the boundaries of the constellation Canes Venatici, M63 bleongs to the M51 Group of galaxies which is around 37 million ly distant.
