The closest galaxy to us is the one we are in. The Milky Way.
Visible on a dark clear night from anywhere on the planet as a vast bulging band of diffuse light.
Long exposure photography brings out fascinating detail as we look toward the center through several spiral arms, we now know that there is a hidden black hole at the very center, approximately 25,000 light years away..
Also visible to the naked eye , 158,000 light years away and exclusive to the Southern Hemisphere are two satellite galaxies of the Milky Way. The Large (LMC) and Small Magellanic Cloud (SMC).
Concentrating here on the LMC, long exposures reveal an exotic array of twisted, knotty gas forming some of the most complex gaseous features you will see.
As these galaxies are being gravitationally deformed by the vastly more massive Milky Way. It is expected that one day in the distant future, they will be one.
