M63, The Sunflower Galaxy


Click image for larger version.


M63 is a spiral galaxy in the constellation Canes Venatici (the Hunting Dogs).  It is about 37 million light years distant and a member of the M51 Group.


Visually the galaxy takes on a grainy texture due to the fine concentration of dust lanes within the galaxy's short spiral arms.
