Llyod, " I don't think the other star would have been close enough to the solar system to light up any of the planets." You've nailed it. If I could ask Thornhill one question that would be it: "Could another star be brought close enough at z-pinch to not only rearrange our planetary system, but visibly light the nearest sides of each planet?" I know Thornhill has not spent enough time theorizing what would happen to our system at z-pinch, or he would have been the one telling Talbott how that crazy polar alignment came to be. As far as Talbott maybe overlooking the correct shape of Mars, that's a definite no. He shows too many depictions of that crescent Saturn with that round Mars dead in front of it. That's one observation we must account for in any theory about our ancient sky.

Llyod, From the first of your posts back on Feb 22,2012 You may be interested in this: http://www.iovs.org/content/30/10/2265.full.pdf The human eye is not very adapted to night vision. But we don't see very well in the bright daylight either, without sunglasses. A little more technically correct here, would be to say that many current eye diseases (cataracts, retinal damage, etc,) seem to be caused by exposure to sunlight in the U-V portion. Here we have adaptation in mice ,to U-V. Could it be that mice, which reproduce much more frequently than humans, have adapted to a different "sun"? It would be interesting to follow up (for those into biology), when the departure of mice into separate groups occurred (was the enhanced ascorbic acid a recent adaptation?). It would be interesting to see trends in ascorbic acid in other animals , if that is occurring. Not a quick response from me here, just something I stumbled on. May turn out to be nothing, but worth a read, I think.
Here is what Saturn may have looked like in the daytime sky. The glow around Saturn would be mainly the plasma sheath, plus some influence from our atmosphere. In space both would have looked a bit brighter and bluer but not significantly, so this would roughly represent what you'd see on the surface of the Earth or in space.

I got my cues for the image above that I created from this image below that I found and a modified one below, as well as other sources:

I forgot to add that chlorophyll of green plants utilizes both red light and blue light for photosynthesis; green light is not utilized and that is why chlorophyll is green. On the surface of the earth, the majority of light received is yellow and green. Yet a brown dwarf like Saturn would emit both red and blue light due to the way it's powered electrically. Therefore, chlorophyll was MADE for brown dwarf Saturn-light, and NOT the present day sunlight. In fact, in outer space, the sun would look blue white!

I guess those images are from the Saturn Death Cult website. Thanks for the info about biological adaptation to light etc. Can you provide links for reference? That would be helpful.
Chlorophyll (also chlorophyl) is a green pigment found in cyanobacteria and the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, chloros ("green") and φύλλον, phyllon ("leaf"). Chlorophyll is an extremely important biomolecule, critical in photosynthesis, which allows plants to absorb energy from light. Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion. However, it is a poor absorber of green and near-green portions of the spectrum, hence the green color of chlorophyll-containing tissues.[1] Chlorophyll was first isolated by Joseph Bienaimé Caventou and Pierre Joseph Pelletier in 1817.[2].....
.....Why green and not black? Black plants can absorb more radiation, and yet most plants are green
It still is unclear exactly why plants are mostly green. Green plants reflect mostly green and near-green light to viewers rather than absorbing it. Other parts of the system of photosynthesis still allow green plants to use the green light spectrum (e.g., through a light-trapping leaf structure, carotenoids, etc.). Green plants do not use a large part of the visible spectrum as efficiently as possible. A black plant can absorb more radiation, and this could be very useful, if extra heat produced is effectively disposed of (e.g., some plants must close their openings, called stomata, on hot days to avoid losing too much water, which leaves only conduction, convection, and radiative heat-loss as solutions).[7] The question becomes why the only light-absorbing molecule used for power in plants is green and not simply black.
I hope this helps. Saturn's radiation would have been mostly red light, but also a lot of blue light due to the corona and plasmasphere generating blue, UV and X-ray light via the electrical power that Saturn received as a brown dwarf. The color would have been magenta and many LED lights for plants are that color, which the plants love. Thus, chlorophyll would be perfectly adapted to Saturnlight, not the harsher sunlight of our present sun; that would explain why chlorophyll "spits out" most of the blue-green, green and yellow-green light and uses blue and red light.
