    Default The view from within a globular cluster



    Imaging densely packed globular star clusters like M10 got me wondering what the night sky would look like to someone living on a planet deep in the cluster so I googled it and came up with this link to a really interesting article from 2014.

    If you were close enough to the center, the skies may never get truly dark enough to see anything. Or, you may be in orbit around a system with multiple stars. In which case, Isaac Asimov's "Nightfall" story comes to mind.

    The view from Earth is pretty good, I think.

    The prospects for doing astronomy from there would be discouraging. The biggest problem would be the sheer amount of light from all those stars. The cluster's suns would combine to give an average sky brightness some 20 times brighter than Earth's night sky at Full Moon (or about 16.7 magnitudes per square arcsecond).
    And I think I have it bad where I live.

    I think of Asimov's book every time I get good resolution in a cluster - wish I could remember which cluster it is, In his Celestial Handbook Burnham actually calls the book to mind after viewing.

    I dont think he ever gives the cluster a name. We know there were 6 elements to the star system, but not much beyond that, other of course that the system appears to be an outrider of a globular cluster.

    Yes, that’s what came immediately to my mind when reading this thread. There is something deeply affecting and memorable about that story.

    Sorry, unclear. Burnham mentioned Nightfall in his Celestial Handbook. I have to look up what cluster inspired him, thinking it was M5 in Serpens.

    wow that would be a bright place at night and you could read you paper in that amount of light. Sleeping would also be a problem and in fact you could probably see stars in the daytime too as bright as they would be...
