See the return of the Andromeda Galaxy | Astronomy Now.This image of the Andromeda Galaxy, Messier 31, also shows its satellite galaxies, Messier 110 (top) and Messier 32 (lower right of M31’s nucleus). Dust lanes between the spiral arms of M31 can be seen in large amateur instruments, but the bright nucleus, M32 and M110 are easy targets for small telescopes. A 65mm f/6.5 refractor and Canon 1100D DSLR were used to capture this portrait of our largest galactic neighbour from rural Norfolk on 29 November 2013. Magnitude +4.5 nu (ν) Andromedae is the blue star in the lower left. Image credit: Ade Ashford.
