, Studied astronomy in school. Blue light is scattered in all directions by the molecules of air in Earth’s atmosphere which starts at ground level and goes onward to about 330,00 feet. However most of the scattering of light occurs where teh atmosphere is denser (lower altitudes).

What is Colour sky?
Gases and particles in Earth’s atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
then How high does the sky turn black?
The sky is dark at about 80 km up, the top edge of the Mesosphere (at Mesopause). The atmosphere extends all the way up to 800 km, but it’s very, very thin up that high. The ISS is orbiting at about half that altitude.
Why Earth looks blue from space? – The earth is largely (71 percent of the surface of the earth) covered by water. Water blocks the radiation of white light (sunlight). … As illumination enters the water, the water consumes white light and reflects just blue light, lights of all colors. The earth from space, thus, looks blue.
Why does the sky turn black?
Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space. Since there is virtually nothing in space to scatter or re-radiate the light to our eye, we see no part of the light and the sky appears to be black.
What Colour is water? The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.
Is the sky black? Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space. Since there is virtually nothing in space to scatter or re-radiate the light to our eye, we see no part of the light and the sky appears to be black.
Is the sky cyan? Deep sky blue is an azure-cyan colour associated with deep shade of sky blue. Deep sky blue is a web colour.

Is the sky darker at the top of Mount Everest?
At the much higher altitude of Everest’s summit (8,850 m), the sky directly above is very dark blue (almost black) even during the middle of the day when the bright bright sun is high in the sky.
What does the sky look like on top of Mount Everest? On clear days the sky is blue at the top of Everest. On cloudy days it’s grey, and at night it’s black; much the same as everywhere else on earth. Below are a few photos of the summit to illustrate the point.
Why does the sky appears dark at high altitude?
The scattering of the light takes place because of the particles present in the atmosphere. At high altitudes, due to the absence of the atmosphere, the scattering of light does not take place. Hence, the sky appears dark to the passengers flying at high altitudes.
Why do we never fall off the Earth? A force called gravity is pulling you down towards the centre of the Earth. Anything with mass also has gravity, the more mass something has, the stronger the pull of gravity. … So we don’t fall off the Earth at the South Pole because gravity is pulling us down towards the centre of the Earth.
What makes the sky red?
During sunrise and sunset the sun is low in the sky, and it transmits light through the thickest part of the atmosphere. A red sky suggests an atmosphere loaded with dust and moisture particles. We see the red, because red wavelengths (the longest in the color spectrum) are breaking through the atmosphere.
Why do astronauts see space black?
Due to the lack of atmosphere in space, light does not get scattered into its constituent colors in space. On earth, due to the atmosphere, the scattering of light takes place. This is why the sky appears dark instead of blue to an astronaut in space.
Why can’t you see the sun in space? It depends on what exactly you mean by visible, but if you can see the sun (which you can from outer space) then that means it’s light is visible. … In space, or on any planet or moon that doesn’t have an atmosphere, there’s nothing for the sunlight to bounce off of so the sky is always black.
Is the sun black? As with all matter, the sun emits a “black body spectrum” that is defined by its surface temperature. A black body spectrum is the continuum of radiation at many different wavelengths that is emitted by any body with a temperature above absolute zero. … So one might say that the sun is blue-green!
What Colour is space?
Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there’s virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.
What color Is A Mirror? A mirror might look silver because it’s usually depicted that way in books or movies. However, it’s actually the color of whatever is reflected onto it. A perfect mirror has specular reflection, meaning it reflects all light in a single direction equal to what it receives.
What is the Colour of blood?
Human blood is red because hemoglobin, which is carried in the blood and functions to transport oxygen, is iron-rich and red in color. Octopuses and horseshoe crabs have blue blood. This is because the protein transporting oxygen in their blood, hemocyanin, is actually blue.
What is the Colour of Earth? Short answer: Mostly blue, with some green, brown and white. Long answer: There are several main colours of the planet Earth, the dominant colour being blue. This comes from the oceans and the atmosphere. Water is blue when it’s more than a few metres deep, and the oceans also reflect blue light from the atmosphere.
What color is the sky on Mars?
The blue color near the Sun is not caused by clouds of water ice, but by the Martian dust itself. The dust in the atmosphere absorbs blue light, giving the sky its red color, but it also scatters some of the blue light into the area just around the Sun because of its size.
Is the sky Purple? If we judge by the most prominent color, the sky is violet. But the sky appears blue due to the limitations of our eyes. Our sensitivity to light decreases as we reach the shortest wavelengths of the visible spectrum. The violet is there, but our eyes detect it only weakly.
