I promise this is the last look back at last year's photos. Today's hero is the Andromeda Galaxy classified as Messier 31 and its satellite galaxies M32 and M110. By the way, this is my first astro photo, and it was saved after really long months when I made the best possible decision as an astrophotographer and purchased the PixInsight software. The initial versions of raw data editing, as well as errors at the light collection stage, practically disqualified this photo from any consideration for publication, but a bit of experience and better tools produced a quite eye-pleasing image.
Observations by the Hubble Telescope in 1991 indicate that the Milky Way, almost twice its size and closest neighbor, may have a double core, which may be the remnant of a former collision and absorption of a smaller galaxy. In 4.5 billion years, Andromeda will most likely collide with our galaxy, resulting in an even larger galaxy. A similar collision can currently be observed in the Antennae Galaxies (NGC 4038 and 4039). 2 replies
