Ahhh just got back.. kids in bed and time to read up the thread...
I must say I’m shocked at how many people don't understand how light reflects and refracts.
It's a total travesty and a lot of you need to go back to school.
First let me say 100% definitely that the atmosphere we have here on earth is the reason we cannot see the stars throughout the day, sunlight
scattered at a brightness level that is equal or greater than the light of the stars....
Though those who know the skies may point out that Sirius the brightest star is often seen during day time and for that matter so is the planet
The moon does actually have an atmosphere though it is so slight that it would make zero difference to light refraction.
Yes it's true from a photographers point of view taking images where there is very bright areas right next to very dark areas is a complete
And yes the iris will react to light to reduce the total amount of light entering the eye..
However.... I reiterate....
It would be possible to create the correct circumstances whereby the astronaughts could have quite clearly seen the stars. Just as going into the dark
room from a bright room... your eyes to begin with can’t see a thing but after some time your eyes slowly begin to adjust and hey presto you can see
and wondered why you thought it was so dark earlier....
It would have only taken 10 minutes of their time to place themselves in a position where no light was reflecting on their visor and under these
conditions their eyes would adjust to the new light levels and the star field would have grown in intensity to show what surely would have been a
The fact that they didn't even attempt this is very very telling...
Then we have the astronaughts reaction when asked about the stars....
For anyone who debates about light through an atmosphere please refer to here...
Why can't you see stars during the day?
Stars do glow during the day, but we can't see them because of the glare of sunlight. When the sun is up, the blue colour in sunlight gets
scattered all over the atmosphere, turning the sky the familiar bright blue colour. This blue light is much brighter than the faint light coming from
the stars, so it prevents us from seeing them.
If you were standing on the Moon, for instance, where there is no atmosphere, you would see the stars both day and night.
Hope this helps,
