Description

The Whirlpool Galaxy is the brightest member of the M51 Group, a relatively small group of galaxies that also includes the famous Sunflower Galaxy (M63) and the fainter edge-on spirals NGC 5023 and NGC 5229.Messier 51 is classified as a Seyfert 2 galaxy, an active galaxy with a quasar-like nucleus, a very high surface brightness and a characteristic bright core, one that appears particularly bright at infrared wavelengths.The Whirlpool Galaxy is interacting with a smaller companion, NGC 5195 (Messier 51b), a dwarf galaxy connected to its larger neighbour by a tidal bridge of dust. The bridge is visible in images of the pair silhouetted against the central region of the smaller galaxy.
