Messier 63 (also known as M63, NGC 5055, or the Sunflower Galaxy) is a spiral galaxy in the constellation Canes Venatici consisting of a central disc surrounded by many short spiral arm segments. M63 is part of the M51 Group, a group of galaxies that also includes M51 (the 'Whirlpool Galaxy'). M63 is an active galaxy with a LINER nucleus.[3]

History
M63 was discovered by Pierre Méchain on June 14, 1779.[4] The galaxy was then listed by Charles Messier as object 63 in the Messier Catalogue.
In the mid-19th century, Lord Rosse identified spiral structures within the galaxy, making this one of the first galaxies in which such structure was identified.[4]
In 1971, a supernova with a magnitude of 11.8 appeared in one of the arms of M63.
