    Default How many galaxies can you see from Earth with naked eye and between galaxies....



    Did a little checking and it seems that we can see about 8 galaxies with the naked eye from Earth. I assume that to the average person (and possibly everyone else) they would look pretty much like a random star looks.

    This had me wondering. Having watched sci-fi most of my life any time a show (like Stargate) shows a ship sitting in the void between galaxies it looks no different than it looks when the ship is just floating in space within a galaxy.

    I was wondering if I am right in thinking that this is totally wrong. A ship sitting halfway between the Milky Way and the Andromeda Galaxy should be sitting in near absolute black with maybe a couple dozen individual dots of light from the various galaxies that one can see. Basically just like if how the night sky would look if we omitted all the stars, planets, moons, etc. Am I right? If you looked out the window of your spaceship while in the void would you be looking out at near endless black nothing?

    Unhappy Re: How many galaxies can you see from Earth with naked eye and between galaxies....

    I think you're basically correct. Given the average distance of stars that we can see naked eye on earth is in the 400 to 1000 light year (ly) range, and given a Milky Way-sized void distance of 100,000 ly at a minimum (and many times that at a maximum), you should be seeing mostly blackness. You might see one or two patches of light from distant galaxies, and perhaps one or two wandering (intergalactic) stars but depending on the distance of the void and the frequency of wandering stars, you would be surrounded by blackness.

    The theoretical number of possible naked eye galaxies one can see on Earth might be 8, but for my neck of the woods in the light-polluted northeast, and with my older eyes, I can't even see Andromeda naked eye.

    Hello Limemmober,

    regarding the galaxies in the northern skies, I am aware only of the Andromeda Galaxy M31 and of the Triangulum Galaxy M33, as reported with unaided eyes. I can frequently see the M31 from my backyard.
    This article https://www.skyandtelescope.com/obse...sky-naked-eye/ deals with the naked eyes astronomy.

    I have put in 2011 a thread on the deep sky objects with naked eyes
    DSOs with naked eyes
    it is hybernated, so you can read it, but don't post replies to it, leave it to sleep.

    Here is the list of the proven DSOs reports with the naked eyes
    Deep Sky with the Naked Eye

    This initiative has been started in Germany and organized by matthias.juchert@serifone.de

    Myself, I have nailed down dozens of the DSOs with naked eyes during our stay in the Mt Ventoux area in Provence (France).

    Best,

    So if you "stopped" halfway between Milky Way and Andromeda the visually you might see a a few galaxies and "possibly" a rogue star if you just happened to stop at the right spot.

    I can confirm with my unaided eyes just 2 galaxies, the M31 and M33, and the M33 just once seen, in the northern skies.
    The other DSOs reported with the unaided eyes are the clusters, some emission nebulae, and a few dark nebulae.

    We can add Magellanic Clouds for sure, this brings the count to 4.

    Yes, BigZmey,

    but I have seen them from South Africa, this does not count for thze northern observers.

    Just wanted to point out the fi in sci fi. The producers just want pretty images that the average audience 'thinks' space might look at. A black void would be pretty boring

    This is an interesting topic. A couple of nights ago, while resting my eyes after looking at some DIM galaxies in Hercules through the scope, I laid on my back in my driveway and was able to see M92 with my naked eyes.
    I think I may take up this new challenge, although the brighter Messier objects that are low to my southern horizon might be impossible from my latitude. I think the only galaxies I have seen without optical aid are M31 and M33. I'm amazed that some have seen M81 and M101 with only their eyes. Might have to try it.
