  • Have you ever wondered why the sky is blue? Neil deGrasse Tyson is here to help you answer that question alongside comic co-host Chuck Nice. And, you’re about to find out why the answer is easy to understand, but not that simple.
    You’ll learn how the white light from the sun interacts with the atmosphere through a process called “Rayleigh scattering” that makes the sky blue. Neil tells us why the sky turns different shades as the day goes on, and why the sunset changes from blue to amber.
    Discover why the reason we have a blue sky is the same reason you can’t see stars during the daytime. And, how this lead to the discovery of the operational definition of where the atmosphere ends and space begins. Neil explains why he thinks space should be defined by gravity and not by the circumstances of our atmosphere. Lastly, Neil gives us a lesson on the frailty of our atmosphere and our delicate place among the stars.

    Two things...first, I love how Neil can be so intelligent and in a blink can come down and enjoy humor that most of us share. Second, I had always thought that the sky was blue because sunlight was being reflected off our oceans into the atmosphere. Makes me start rethinking what else I have so drastically misunderstood.

      me too - however, i only hated science at that point, because it could not answer the things i wanted in sufficient depth to fully grasp and understand the universe we live in - now however, i envy those going to school, as the amount of knowledge gathered since i was in school, is mind blogging. and in case i am 38, so was a long time ago. hence, science can now answer to the degree of understanding i want/need. Biggest issue i had in school, was the way it was taught, never taught to understand, just taught things to repeat, so i would sit there and say how is that, how does that happen, why does that happen, and as you can guess couldn't get an answer, so lost interest in it. And at risk of repeating, now they can fill in those blanks and explain things fully, like evolution, and my passion for learning is re-ignited.

      Likely the air conditioning is turned down to about 62°F, and if you're skinny, you feel the cold more intensely. That's my hypothesis, anyway. Since NDT is wearing a long sleeved shirt of some type under a short sleeved shirt, so he has at least 2 layers on, himself. Maybe a 3rd, if he has an undershirt on, too.

    In the fifth grade, I remember our teacher giving us a question that read, "What color is the sky?"
    I was a super nerd and loved reading. So, by the time I was in 4th grade, I was reading encyclopedias for fun, learning tidbits that I wouldn't really come across until HS.
    To shorten this story, I explained in detail similar to how Dr. Tyson described it about how the light from the Sun scatters in our atmosphere and the color that is reflected is what we see (much like how grass absorbs all the other colors that make up light and reflects green).
    Well, my teacher straight up gave me an F for the assignment!! 😡 I was so crushed because I knew I was right and when I went to talk to her about it, she just brushed it off. This was over 20 years ago, but it's great seeing videos like this on UA-cam! Bill Nye, The Magic School Bus, Reading Rainbow, etc were among my favorite shows as a kid!! 😃

    The reason for that is the presence of oxygen molecules in the glass.
    Liquid oxygen is bluish.
    The color of the sky is blue, just like glass, because of the oxygen in the atmosphere 💙.
