Can you see the atmosphere with you eyes or only through photos? (In space)

  1. Apr 22, 2015 #1
    Among my favorite space photos are those in which you can see the earths, or other planets atmosphere, and I've always wondered if this was something like you can't see a galaxy with the naked eye, unless you use really long exposure times in your photos?

    seeing or not seeing other galaxies isn't dependant on our atmosphere
    There are 4 or 5 galaxies that we can see with our naked eyes

    1) our own Milky Way Galaxy
    2) LMC = Large Magellanic Cloud
    3) SMC = Small Magellanic Cloud
    4) M32 Andromeda Galaxy
    and some people with awesome eyesight in a dark location can see
    5) M33 The Triangulum Galaxy

    all the rest are very faint and need telescopes or very large camera telephoto lenses to see or photograph

    still considering the best way to answer this part....

    OK try this I found on google .....

    Blue light is scattered more than other wavelengths by the gases in the atmosphere, giving Earth a blue halo when seen from space onboard ISS at a height of 402–424 km.

    how's that grab you ?
    and you don't need a camera to see it .... even at around 30 - 40,000 ft in an airliner you start seeing that :smile:

    cheers

    I was referring to the non obvious galaxies, but I take your point

    Yes of course you can see atmospheres. When you set at sky you can see blue sky, which is atmosphere. It can be seen because particles or atoms on atmosphere refract sun light which let's is see atmosphere :rolleyes::)
