The Sunflower Galaxy, M63, is a spiral galaxy in Canes Venatici and lies some 30 million light years away. It is a flocculent (meaning fluffy) spiral galaxy which has no defined spiral arms, in contrast to grand design spiral galaxies like M81 or M101. Self propagating star formation is one explanation for the structure of these galaxies.
