Description

The Sunflower Galaxy (Messier 63, M63, NGC 5055) is a spiral galaxy located 25 million light years away in the constellation of Canes Venatici (the Hunting Dogs). It comprises a central disc surrounded by short spiral arm segments. The disc is around 100,000 light years in diameter.

The galaxy was first observed by Pierre Méchain on 14 June 1779.

Messier 63 exhibits very faint extended features just visible in this image. These are probably the result of gravitational interactions with nearby galaxies.

Messier 63 was photographed between 4 May and 2 June 2019 from an imaging rig in Spain that is privately-owned and remotely-operated by Barry Wilson and me.
