M63 - Sunflower Galaxy
The Sunflower Galaxy (also known as Messier 63, M63, or
NGC 5055) is a
spiral galaxy in the
constellation
Canes Venatici consisting of a central disc
surrounded by many short spiral arm segments. The Sunflower Galaxy is part of
the
M51 Group,
a group of galaxies that also includes the
Whirlpool Galaxy (M51).
The Sunflower Galaxy was discovered by
Pierre Méchain on June 14, 1779.
The galaxy was then listed by
Charles Messier as object 63 in the
Messier Catalogue.
In the mid-19th century,
Lord Rosse identified spiral structure within the
galaxy, making this one of the first galaxies in which such structure was identified.
In 1971, a supernova with a magnitude of 11.8 appeared in one of the arms of
M63.
