The surroundings of the Andromeda Galaxy!

 The Milky Way has a big neighbor: the Andromeda galaxy (M31), which is approximately 2.5 million light-years from Earth and is considered one of the brightest objects cataloged by the French astronomer Charles Messier.  It can be observed with the naked eye on New Moon nights and even in places with greater light pollution.  Like the Milky Way, the Andromeda galaxy is also part of the so-called Local Group, formed by more than 50 galaxies, being surrounded by some small satellite galaxies — and the image above shows us some of the details of its surroundings.

 If you look at the top right corner of the photo, you will find the Triangle Galaxy, a spiral galaxy three million light-years from us and considered the third largest in the Local Group, as well as being the most distant object that can be observed in the sky. night to the naked eye.  Below it is the star Mirach, the brightest in the constellation Andromeda.  In the middle of the image is the galaxy M31 and, in the lower part, the nebula Sh2-126, which appears with its reddish filaments.  It was possible to bring these various objects together as a result of the digital accumulation of a series of long exhibitions, made from 2018 to 2021.
