Why The Sky Is Blue In Color? Everything You Need to Know about Sky and Science
The photos from NASA will show that during the daytime, the sky on Mars is of an orange or reddish color and takes on a blue-gray shade after the sunset. It may appear strange to us as humans on the planet Earth to see an orange sky during the day and a greyer sky at night
Nature, the habitat we live in, the flowers we smell, the plants and trees that we water regularly, are all a blessing from God. It is nature that is the first one to help us identify and differentiate between different types of colors and shades. Have you ever wondered how our kids would have differentiated between the various shades of green had there been no greenery in the form of trees, and bushes around us? Or, what if everything natural tended to appear the same color? The stars, the flowers, the clouds, the rays-all carry the same color. Will it not look like humans live in monotony?
But, did you ever wonder how these natural elements of God get their color? Where do they extract the color for themselves? For instance, let’s talk about the sky. We are all in love with the charm a blue sky holds. But how many of us exactly know how the sky got its color? Why is the sky blue?
Did the sun do the magic?
It is because of the light passing from the sunlight through a prism. This could probably be the shortest and “easiest” answer to go with. But let’s talk about the depth of it. The white light that comes out from the sun slams through a prism, which in turn, produces seven colors of rainbow. All of us know what a prism is. It is a specially shaped crystal, and any color that passes through a prism comes out in seven different colors. These give the VIBGYOR color pattern. Many of you will now feel like going back to your high school’s physics class. We did study light and its functions in school, but all the logical aspects were left behind, hidden in the books, and we all grew up.
Let’s Get Deep Into It.
Like energy passes through the oceans. Light energy also passes in waves. Light moves in a straighter direction unless there is something striking on its way. Sunlight enters the Earth’s atmosphere and is dispersed in all directions by the gases and particles present in the atmosphere. Now, because blue is the only color to travel in smaller and shorter waves, it diffuses more than other colors of the rainbow. Therefore, the small molecules of air in Earth’s atmosphere disperse blue light in all directions, and all we get to see is a blue sky, most of the time.
How Does the Sky Look On Other Planets?
Well, we just talked about how the sky looks on our planet Earth. But, is it the same situation on other planets as well? Does the sky appear blue on all the planets, or is it just the Earth? This is something that is entirely dependent on the environment there. Taking the example of the planet Mars, Mars has a very thin atmosphere made up mostly of carbon dioxide. It depends and is also filled with fine dust particles. These small particles bounce light differently than gases and particles in the Earth’s atmosphere.
The photos from NASA will show that during the daytime, the sky on Mars is of an orange or reddish color and takes on a blue-gray shade after the sunset. It may appear strange to us as humans on the planet Earth to see an orange sky during the day and a greyer sky at night. But on Mars, this is what happens based on the atmosphere. So, now you know why the sky is blue and how it all works behind the color we see. Next time you come across someone who is discussing the beauty and color of nature, tell them about why the sky is blue and share your knowledge to learn more.
