Description

Object: The Andromeda Galaxy – M31 (Oct. 2018)

(Messier 31, M31, or NGC 224)

The 4th and last time I am doing this target. I was visiting an old friend in Nova Scotia and I needed to come up with a wideband target quickly and M31 won out.

A large spiral galaxy in our “local group” of galaxies named for the mythological princess Andromeda and located in the Constellation of Andromeda. The galaxy is estimated to be 2.5 million light years distant and is estimated to be 220,000 light years across with a halo weighing in at 1.23 trillion solar masses containing over a trillion suns within its boundaries.
