We now know this galaxy is about 27 million light-years away and belongs to the M51 Group -- a group of galaxies, named after its brightest member, Messier 51, another spiral-shaped galaxy dubbed the Whirlpool Galaxy.
The galaxy is officially named Messier 51 (M51) or NGC 5194, but often goes by its nickname of the "Whirlpool Galaxy.
Mention the words 'Canes Venatici' and 'galaxy' to many amateur astronomers and Messier 51, the Whirlpool, springs to mind.
Fifty five members submitted observations during the year, an increase on the 2009-'10 figure, boosted by the supernova 2011dh in Messier 51 which proved a popular target.
