I felt sleepy and included about another thread. Thanks AlexG but no thanks. These is another thread and you're following me from there.
Now, regarding this thread:
- The space is much colder even when one is infront of the earth facing the sun.
High up in earth's atmosphere, snow forms on the tallest mountains. Perhaps, we can hear the points of view from skydivers, hot air balloonists, etc. what they observe.
It is obvious though that as you go higher in the atmosphere, temperature drops. Temperature can drop low enough that water vapor in the air begin to form ice crystals that become snow.
It is indication that the thickness of the atmospheric layer through which the sun's rays travel, the more heat is generated. In other words, the radiant energy begins to manifest heat only in the presence of particles it bumps into. The sun is unlike a flame that transfer energy by heat conduction.
Halley's comet observed to be made of ice and dust could have not survived several trips around a giant ball of nuclear furnace.
Here is a page I found:

"..Scientists measure the temperature on the sun by examining its color. Just like a hot iron bar changes from red to "white" hot as the bar heats up. To me this is the same thing as concluding that the sun rotates around the Earth because it seems to rise in the East and set in the West, or that the Earth is flat because the way it looks from the surface. Because iron changes color as is heated, and because we see those heated-iron-colors in the sun, the conclusion is that the sun behaves like iron and is hot and its emitting colors are indicative of the temperature at its various points. Is it not still thinking with the "flat-Earth mentality"? .."
Using color as proof that the sun is hot might be misleading, for example when a colored led bulb emits the hue of light coming from hot metal.
