@neiltyson Is the sun actually white and not yellow?
-
-
then wouldn't astronauts see the sun as white from space/moon?
-
Astronaut helmets have UV filters. Used to be made from gold (still are?).
-
but would that really be enough of a difference to make the sun appear yellow/orange to them?
-
yes, if I wear tinted yellow glassed for cycling then the whole world looks yellow

White to our eyes due to sensitivity limits, but it has a slight yellow/green tint to an electronic detector.
