Neil deGrasse Tyson Explains Why Stars Twinkle

Thanks to Salesforce for sponsoring a portion of this video.
www.salesforce.com/startalk
Have you ever wondered why stars twinkle? Do you know why astronomers hate twinkling stars? On this StarTalk explainer video, Neil deGrasse Tyson and comic co-host Chuck Nice are going to give you the answers.
In order to understand twinkling stars we need to understand how far away the stars are from us. You’ll learn just how big and empty space can be. Neil gives some examples to put the distance between celestial objects into perspective.
Find out about convection and mirages. Neil explains how the same scientific processes are causing stars to twinkle in the night. We discuss how the starlight is refracting its way through the atmosphere one pocket of air at a time. You’ll learn how astronomers figured out how to compensate for the refraction and how that led to the creation of "adaptive optics." All that, plus, you’ll find out why the first star you see tonight might, in fact, be a planet.

Salesfarce says the platform can do just about anything, which is correct provided you hire consultants or force your developers to learn and work within their poorly-documented languages, APIs and workflows to custom-build your very expensive solution. What they sell is a multi-tenanted hodge-podge of evil technologies that will rob your business of it's identity, intellectual property and soul (oh let me not forget their ludicrous rate schedule that charges PER ROW OF DATA). This got me so worked up I actually un-subbed.

Neil and Chuck are a breath of fresh air. Btw, the melody itself for English speakers as “Twinkle, Twinkle, Little Star” was written by Mozart (originally “Ah, vous dirai-je, Maman.”) However, the words put to it originated as a poem written by the English author Jane Taylor and was published in 1806 as “The Star.” Sometime later the poem was set to Mozart's melody. I teach guitar to kids and this is one of the first songs they learn, I always mention to them who the composer of the original melody is

[@uridimmuvltozwta1466]

I think this really puts into perspective how empty the universe is. The photons that have traveled for over a billion years in a straight line never once were stopped by another object. Then take that idea and multiple it by all the stars you see in the sky. Despite this epic journey, the photon's journey was stopped by your marble-sized eyeball.

[@chrism3784]

You are right but even more perspective your eyes cannot make out anything a billion light years away. Furthest object in the universe you can see and make out is Andromedia Galaxy which is about 2.5 million light years, and even then it's very faint and hard to see. Something billions of light years away and you look towards it, only a few photons of that object may hit your eyeball a minute, if that. That's why we need really large optics like the Hubble to stare at it for hours, collect the small amount of photons hitting it and then draw a picture from it.

Fun fact Neil : the word " short " is longer than the word " long "

[@pulkitmohta8964]

Well you have "tiny" which is just as long as "long"

If a star is twinkling due to atmospheric interference, it's actually pretty hard to discern anything concrete about it. Size, distance, composition, it's all distorted. "How I wonder what you are", indeed.

[@ryanoneill7099]

Dr. Tyson should put the star talk spin on “shooting stars”!!! Always look forward to these segments! Great bit of educational entertainment

[@dangrigore.]

Always a pleasure listening to this man, i supose is quite stresfull for someone with this level of knowlege to explain to us, "normal people", how things work. I'm from Romania and i'm very glad for learning english language myself, cuz now i can access this kind of informations presented like that by Neil. These discutions are essential guys..

[@istvansipos9940]

Neil used the name Timmy ages ago when he was talking about alien kids. Why is he suprised now? (that's a fun talk, by the way)

[@ashwinkamath99]

Irony is hitting this show real hard, the background seems like it was taken from space and not from the earth and yet it's twinkling, oof

[@davidevans3227]

these explainers remind me of when i was sort of 9, 10, 11 years old and i shared room with my brother who was older than me, doing his "o" levels (exams at 16) and "A" levels (exams at 18) ..and we would sit up late into the night, we had an ordinance factory ten minutes away, making part for nuclear weapons (apparently?) ..that was a good topic for speculation lol.. He would tell me about the atom and molecules.. the solar system the sun and planets.. earth, nature.. and so on.. he gave me such a good base of knowledge to enter high school.. thanks tim.. 🙂 and thankyou for sharing this..

[@kaufmanndulany4409]

Man, you both of you are great...keep the great content coming.

btw the background has stars that disappears in and out of existence.

Not sure if "existence" is the right word, perhaps "visibility."

Hello everyone. Hope you are all doing well. I must say that I love Star Talk. This program is so much more informative than any of my College Science courses ever thought of being without a doubt. Just a quick note from my High School days... My friend Bev and I wanted to start a band and call ourselves Stellar Spectra. That was when we were in 10th grade 1967. I might be old but I still enjoy learning.

[@TheWeatherbuff]

Hey! I knew most of this because I'm a meteorologist. Chuck: Nice job on the commercial. (Yes, I actually watched it because I do voiceovers too.) Very well done! Neil: You're a rock "star". BTW, my forecasting motto: "80% of the time, I'm right, EVERY time." Thanks guys!

I’d love to have some videos of just Neil talking into the camera it has a much different flow than a conversation dose.

[@hantihut8141]

Would be lovely with a explainer on all the terms you astrophysics use (planet, star, galaxy, milkway etc) and how they work together and more distance explaining - so we so to speak can be planted on the same boat :-) Love your work by the way:-)

::::: ...So it does not matter how much you zoom in, STILL planets, the sun and moon do not twinkle like stars.., so gravity even produce colors in the stars light.., i just don't think so. Jesus said:"Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name and in your name drive out demons.." -Matthew 7 How did that "man" know that more than 2 thousand years AFTER HE DIED; ALL THAT WILL HAPPEN, There are so "Many" christian religions today, doing exactly what he said.

5:24 someone ones told me that if the sun was the size of a Orange and earth a grain of Rice the distance would be from Luxemburg to Moskau

[@RayRay-zt7bj]

Yes, that figure sounds nearly exactly correct. If the sun was the size of a cueball, the nearest star would be 977 miles (1,572 KM) from Baltimore to Miami. A cue ball is approximately 2.17 inches (5.5cm) and is about 25 -30% smaller than an orange. Therefore Luxemburg to Moscow would be somewhere aroundmn1,600 miles (2,575 km) away. That is given that a light-year is approximately 5.9 trillion miles and the distance to the nearest star is 4.2 light-years from the Sun.
