I had a girlfriend in college that I referred to as "My Little Neutron Star" One day she asked me about it, "Is it because I'm so incredibly bright?" "No honey," I answered, "it's because you're so incredibly dense." The supernova occurred right after that.
also, a good argument against flat-earthers: if Earth was flat, you could see Polaris from everywhere on the planet. It's the curvature that blocks the view for southern hemisphere.
The entire thing makes flat earthers look like fools, even tropical astrology Alpha Draconis, aka Thubin used to be the north star before Polaris but due to precessional slippage it shifted to Polaris. Precessional slippage can be tracked by the north star, due to the "wobble", or the shift of the constellations, hence why Aries is behind the sun during the tropical astrological period of Taurus, because Taurus was behind the sun at that time of year when the Babylonians created the Mul Apin, the Babylonian star charts, in the BC time period. Ptolemy reset the zodiac to 10° Aries and froze it around 100ad which is why tropical astrology does not account for precessional slippage.
Two pole-stars and the counter-clockwise rotation in the north, clockwise rotation in the south is the checkmate of any flat earther.. ..Couldnt happen on flat earth, space would have to have an equator, with each half of the universe rotating opposite around Polaris and Sigma Octantis every day!
Another fantastic episode of Star Talk. Just one feedback: please explore the use of animations or still images to explain some of the more technical topics.
Good video Neil and Chuck. You started talking about people’s misconception that the North Star is the brightest (in the Northern Hemisphere) but I didn’t hear you say which one is. You danced around it a bit with Chuck citing Sirius, but he did so in connection with the North Star (for which he was corrected by Neil) not the brightest. For viewers who may be interested, Sirius is indeed the brightest star as viewed from Earth.
@@linyenchin6773 Not really, just completing the thought that Neil started at 3:08 when he said, “we’ll get to the brightest star in a minute" but never did.
No where in your OP you said night sky for asking about the brightest star. So in your OP question about the brightest star, the answer is of course the Sun. And yes, I am fun at parties. HAHA
Chuck doing directions is *literally* how we give directions because direction is hard -- Also, weirdly elated to have guessed Venus as the first "star" we see as we circle Sol, and guessing Polaris correctly.. :I Not sure we, in our thirties, should feel this excitement, but here we are.
Chuck Nice and Neil deGrasse Tyson are the perfect combination of knowledge and humor. I could listen to their talks for hours! in fact i did just did that!
For the Southern hemisphere we've got the Southern Cross (Crux) and the Two Pointers (Alpha and Beta Centauri) which, used together help you find south (Or at least point you close enough to find that Sigma Octantis). Still love the analogue watch trick for finding North/South.
You constantly answer questions from my childhood that I either couldn’t get a straight answer for or that I never thought to ask. I appreciate you so much!
7:02 People don’t “want meaning in the sky”, they want to use an approximation that is very effective. If you’re lost in the wilderness and need to know which direction is North, do you want a pedantic A) Sorry, absolutely no way to know exactly the direction, or B) the North Star is the closest, it is less than 1 degree from true north, and you can use it quite effectively?
Yes please not saying earth is flat but north and south hemisphere has the same views like and constellation meaning south see the same constellation as the north
I really like this episode. I am a retired mariner , have used Polaris to get the ships latitude. Can you talk about longitude by using the time / chronometer ?
6:35 the people are right, there is a star over the north pole that the axis points to, all the time, since there is Earth. We just don't know which one is it, and its not always the same one. But if given enough research, we could actually calculate which star is perfectly north for any day/week of the year.
Answering your questions before you tell us the answers; - The brightest star is Sirius, a binary star system. Sirius A is a main sequence star and Sirius B is a white dwarf. - The north star is Polaris at the moment, but it will become Vega in the future.
The little dude with the flag on Chuck's shirt would have made a decent visual aid. Missed opportunity I guess, but awesome video!(I didn't notice till 15/16 of the way thru). I had heard Architect's Table before and thought at the time that it was strikingly different but never made that connection about the nomenclature of the southern constellations. Thanks for learning me something! And Happy Birthday!
I was a navigator in the Air Force (C-130) and used a sextant (GPS was coming in as I was getting out in the early '90s). To get celestial fixes, we used 3 stars about 120 degrees from each other. We used books that said how high in the sky (by degrees) a star should be based on location and time. In the same way Neil described the 90 degree point at the North Pole for the North Star, if the star you measure is higher in the sky, you are closer to it by one nautical mile per minute of declination it is higher. Do that three times and you get a small triangle (a point if you measure everything perfectly, of three intersecting arcs). The arcs we drew were just a small part of the circle that would be drawn through every spot in which the star would be at the same height. Because all this took time, and we flew on the same heading as we did all the calculations, they allowed us 24 NM on each side of our flight plan! Now we get mad if we're 30 feet off. Navigation has definitely been revolutionized. Thanks for your discussion!
Hi Neil! Happy birthday! I found a video of you dancing at a party and in that video I commented quote "CMON NEIL DANCE ASTRONOMY WON'T TALK ABOUT ITSELF" 😉. During my birthday late last month I was in the hospital dealing with geon bray syndrome so I hope you're having a great time!
Dr Tyson, you keep things real and understandable for us mortals. I live in St Louis, Missouri. This is a terrible place to stargaze because we have so much junk in the air. We have intense humidity because we are in two river valleys. Our altitude is only 400-600 feet above sea level. No stars can be seen on about half of our nights. At best only the moon, Venus, and Mars is ever visible. So thanks for explaining these concepts.
Hey all commentators! It’s well worth the $$ to see this man in person. Been twice and planning the next trip to take my family. It’s like this channel, but live. He is funny, brilliant and there are always some unexpected discussions that take place. It’s StarTalk++.
👋❤️.I hope you do a video about what they in the scientific viuewpoint call " Sirius " because there are a lot of videos about it but i like how both of you bring it , and Neil brings interesting insights as a scientist and how Chuck Nice ask interesting questions with funny but also interesting opinions and insights .🔭🌌
Neal, if your in a ship going the speed of light and you get out of your seat then run to the front of the ship theoretically would you be moving faster than the speed of light?
Very informative as always. If I can add my own 2cents here (as a person from the Southern Hemisphere) I love learning about the night sky as we see it (I.e. show can see the Southern Cross?).
Will you guys ever go back to the old format of Neil and the cohost in his office? I loved that setup so much more, these webcams are terrible quality and just the production quality of the videos seemed higher as you guys were filming with higher quality cameras too. Please consider 🥺
I am just wondering does the north star spin with the earth 1000 mph and going around the sun at 66,600 mph and how do the constellations are always the same no matter what day or year ???
Love these explainers Niel! And Chuck. Chuck I know you mentioned the bump on your head in a earlier vid, did you get it looked at? Could be a lipoma [just a sack filled with skin cells]. I'm not a dermatologist but have watched a ton of Dr. pimple popper. 🤔 North star 🌟 🤩
Polaris was the name of the missile not the name of the submarine. Subs that carried Polaris missiles are called Polaris subs. The first to carry Polaris missiles was the George Washington.
@TheRenaissanceman65 the class of the sub is named for the first vessel in the class. The Geo. Washington is in the Washington class. The Ethan Allen class,the second class of ballistic missile subs also carried Polaris missiles. Other later classes would carry larger missiles such as the Posideon and Trident.
Sir Chuck looks "NICE" #420 as does Dr. Tyson. Blessed rising from Brooklyn NY #STARTALK♡ 😆 🤣 😂 Venus has an attitude 😆 🤣 😂 Nice one Lord Nice or your Lordship
There is a story about two Irish brothers building a homestead cabin in eastern South Dakota. They wanted to align their cabin exactly North & South so they sighted in line with the north star. They were aware of the small error between Polaris and true North. They planned to do one sighting early in the night, wait 12 hours and and sight again, then split the difference for the exact direction. However the night was pretty cold so they took a few nips to keep warm. When they woke up the next morning they decided having their cabin aligned to within one or two degreesof true North was probably precise enough.
You almost had the Polaris-submarine reference right. The first nuclear submarine was the Nautilus, not the Polaris. However, the first submarine-launched ballistic missile (SLBM) was the Polaris missile, started around 1960. To be honest, I only remember that because of the old Batman movie when the Riddler used the missiles for skywriting his riddles.
The North Star, Polaris, is known for its pivotal role in navigation due to its position nearly aligned with Earth's rotational axis. Although it’s not the brightest star in the night sky, its steady position makes it invaluable for orientation. How might future astronomical observations reveal more about the true brightness and characteristics of Polaris compared to other prominent stars?
How do you explain this if the earth spins at an angle and points to different directions through the year. This is why Antarctica gets 6 months of sun and 6 months of no sun.
The point in knowing how to locate Polaris, which also leads to the little dipper, is to get the general direction of north, so as to get your bearings. Southern Crux is the South Hemmisphere equiv, for finding realative South.
Hi guys, hope all is well. I was hoping that you would consider doing a segment about a rock band singer that released a song from 2001. Maynard James Keenan. The song I'm refering to is "Lateralus" the band is "Tool". According to a creator (Polyphonics) Keenan was able to incorporate the fibonacci code and the golden rule into one single song. Its very interesting. I hope that you find time, some time, to check that out. Thank you guys for your educational content!
In case anyone was wondering what is actually the brightest star from Earth, barring Sol, Chuck got it, it's Sirius, in the Southern Hemisphere. In the Northern Hemisphere it's Arturus.
Hello to you mate happy birthday from Australia but listen I got a question ; can we accelerate an atom to faster than the speed of light which is around 3x10⁸ m/s² and shoot to towards the end of the universe provided that no other particles or interference happens will It be able to reach the end of the expanding universe also on reaching the end of the universe will is just ricochet back
Many years ago I learned how to find the North Star. My first thought when seeing it was that it isn't the brightest star by a long shot. I would never have found it if I hadn't known about using the Big Dipper. The North Star is a little bit to the left of the line from BD.
I wish everyone could get a chance to get out of the city to a place where you can lay in the grass and look up to the night sky. It won't take long until u begin to feel Earth rotating.
One of the greatest astrophysics communicators of our generation. There is some tiny leeway that must be allowed when Tyson explains how close the North Star / Polaris is to the North Pole alignment. A couple of moons is relevant for some 🌚 When Tyson states, if someone takes a long exposure picture from the North Pole, it would show it moving in a circle around true north in the sky. This is absolutely (factual) correct, if one was to take a exposure of Polaris that is 12+ hours with a very wide or narrow angle focul aperture. But because Polaris is 323 light years away from earth, a 30 minute exposure image wouldn't "star trail" in a circular motion as he says. Not even from latitudes as far south as the Canadian - U.S. 49° parallel, will show the North Star circling, if the camera is pointed precisely at Polaris. It's harder to do and setup than you think, especially if you're not using a motorized star tracker. I've taken hundreds of pictures 30 to 45 minutes that show star trails in a beautiful and trailing"perfectly", in 360 circles around Polaris. This gives the false perception that Polaris is directly over the North Pole, when it isn't. Given its 323 light year distance, its inclination between true north and where it actual position in our solar system northern position, it's very small indeed and why it is an excellent "analog" naval navigation beacon. ⭐
I had a girlfriend in college that I referred to as "My Little Neutron Star" One day she asked me about it, "Is it because I'm so incredibly bright?" "No honey," I answered, "it's because you're so incredibly dense." The supernova occurred right after that.
And that, kids, is how a relationship collapses into a black hole.
@@JohnDoe-jh5yr yup.
Legend!!!
The brightest star is the Sun!
@@davidharvey3743 In relation to us, yeah, simply because it's closest.
also, a good argument against flat-earthers: if Earth was flat, you could see Polaris from everywhere on the planet. It's the curvature that blocks the view for southern hemisphere.
Well, sure...if you're gonna resort to reason and logic!
FAKE NEWS!
Yeah I didn't think we could see "The Northern Star" from Australia. I think I can actually use the Southern Cross as a compass
The entire thing makes flat earthers look like fools, even tropical astrology
Alpha Draconis, aka Thubin used to be the north star before Polaris but due to precessional slippage it shifted to Polaris. Precessional slippage can be tracked by the north star, due to the "wobble", or the shift of the constellations, hence why Aries is behind the sun during the tropical astrological period of Taurus, because Taurus was behind the sun at that time of year when the Babylonians created the Mul Apin, the Babylonian star charts, in the BC time period.

Polaris right now: “Shut up! I’m the North Star! I may not be super bright but I’m still special! 😭”
Right? She's doing her best. People are so demanding...
How strange is it that science so easily makes me forget about my depression?
Thank you for doing what you do.

I can’t see Polaris from my country because the spherical Earth is in the way.
Love the low key jab at flat earthers. 👍
When did you fall over the edge?
Nah bro you’re just on the underside. Wait 6 months for the Earth to pancake flip over and you’ll be good
Was Siriusly waiting for you to let Chuck know that he did at least know the brightest star in the sky but it never came.
Damn, I'm halfway through the video and was hoping they would circle back to that
I see what you did there
The early name was Osir and related to the name Osiris, this is all supposedly related to the early root of the word sir.

This is absolutely (factual) correct, if one was to take a exposure of Polaris that is 12+ hours with a very wide or narrow angle focul aperture.
But because Polaris is 323 light years away from earth, a 30 minute exposure image wouldn't "star trail" in a circular motion as he says.
Not even from latitudes as far south as the Canadian - U.S. 49° parallel, will show the North Star circling, if the camera is pointed precisely at Polaris. It's harder to do and setup than you think, especially if you're not using a motorized star tracker. I've taken hundreds of pictures 30 to 45 minutes that show star trails in a beautiful and trailing"perfectly", in 360 circles around Polaris.
This gives the false perception that Polaris is directly over the North Pole, when it isn't. Given its 323 light year distance, its inclination between true north and where it actual position in our solar system northern position, it's very small indeed and why it is an excellent "analog" naval navigation beacon.
