The closest galaxy to us is the Andromeda Galaxy – it’s estimated at 2.5 million light-years away.




Before the discovery of the Andromeda Galaxy, the Large Magellanic Cloud was believed to be the closest galaxy to us.

The problem is this: the photons of light that enter your eyes from the Andromeda Galaxy are so few that it goes beyond our eyes ability to make sense of what's there we would have to stare at it for an hour but the problem is this we have a living body and chemicals that transmit our perception of light metabolize before there's enough light entering our eyes to see what is there. So there isn't and won't be enough photons at one time for us to see it clearly you can look at it peripherally and see a slight greenish glow. If you use a camera and a telescope with a equatorial mount and a rotational compensating motor you can do a time-lapse and catch a pretty good image of it but it takes quite some time for enough photons to register on the camera to see color and that is the reason why. Yes it's better to be in a dark area but that really isn't the cause it's the fact that there just isn't enough photons that come quick enough in your eyes.
