Interesting. What is the reasoning?Some of the most accurate clocks built by humans have been based on light emitted by a single atom/ion (mercury and aluminium have been tested).Of course, the light is measured by instruments rather than by the human eye - especially since the light is ultraviolet.See: https://www.nist.gov/news-events/news/2010/02/nists-second-quantum-logic-clock-based-aluminum-ion-now-worlds-most-preciseI am right in thinking we do not detect any light from air? No.The sky is blue.The blue sky is to do with the earths fields not the air. Air has no permeability.

A single atom would be visible if it was lit well enough.
Strangely enough the sky is not even blue, the observer , observes the doppler shift.

That makes no sense.It is not evidence.Do you understand what evidence is?
Either way the astronaut will tell you they do not observer the blue shift because to them the light is travelling away from them.
The running theme of your posts on here seems to be to tear down most of known scientific knowledge and replace it with nonsense that only makes sense to you. Just because something seems logical to you doesn't make it evidence. In the court of science, evidence is something observable, testable and repeatable. "I think it works so it does" is not evidence as far as science is concerned. If you had done the proper prerequisite research, you would understand how Raleigh scattering works and that the Earth's magnetic field has nothing to do with it.Raleigh scattering can and has been measured in the lab: http://www.colorado.edu/chemistry/volkamer/publications/group-pubs/thalman-2014-rscsNArO2air-accepted.pdf

I wonder just how dim it is possible for someone to be.Here's a cropped bit of the image you posted earlier. It's taken from space and it's what an astronaut would see. I have pointed out the fuzzy blue bit which is the atmosphere.

I have pointed out the fuzzy blue bit which is the atmosphere.And by the angle of that shot I conclude the Earth is spinning towards the astronaut , he also observes the doppler blue shift in the distance. Or the astronaut is travelling towards that direction because who knows who is moving.

All the rim is blue.
see my other post on other thread.

The Rim? What about a direct line instead of angled like my provided picture of observation shows no blue sky?
Quote from: Thebox on 25/09/2017 18:20:15The Rim? What about a direct line instead of angled like my provided picture of observation shows no blue sky?You have provided just 1 picture of an observation- the rest are meaningless sketches of yours.The observation is the picture I took a clip from, and it shows that the rim- i.e. the sky- is blue.
Meaningless because of your say so? I think not.
