    Superluminous gallery collection. Thanks BA. :-)

    At first glance the grey insets on the right almost look like Borg cubes!

    The pictures are wonderful but I got hooked on each informative text, compelling me to read through the whole presentation as well as look. Thanks!

    In the “downtown” Andromeda picture, what scales are we talking about? How big is the cluster of blue stars?

    Are you kidding me? We have dark matter maps??

    Can they detect distance as well as direction? Perhaps with parallax? What would a 3D dark matter map look like? Does dark matter tend to clump together? Do I have a lot of questions about dark matter or what?

    The blue cluster in M31 is very compact, fitting within 1/3 of a light-year. The two main peaks of the old red stars in the background nucleus are only 5 ly apart. The angular scale of the image is only 3 arcseconds across, so this a very extreme “zoom” into the center of M31.

    Resolving objects 1/3 LY apart at a distance of 3 million LY is impressive in itself!

    Hi Phil, I really liked your wording for describing the growth of galaxies in the BoRG cluster. I will assimilate them for use in my talks. Thanks for your great blog!

    As soon as man achieved Consciousness, He wondered . . . “what is that?”

    The Green Apple Cosmos. It certainly looks more of a slice picture of the the Big Bang to me. Beautiful 3D indeed!

    I’m not much for royalty, but the wise king and queen panorama is absolutely stunning.

    Somewhere in reading this, I realized it would be really amazing if Celestia included views in non-visible light. (Of course, just having nebulae would be tremendously helpful too.)

    A Neptunian orbit-sized parallax baseline would be very helpful in making that 3D dark-matter map that Christopher Jablonski thought of. We could at least find out how much of what we detect is inside our galaxy.
