  • Oh why hello there! I'm Jake. I am sitting in Michael's

  • lovely floral chair that he sit in for 3 hours

  • for the prime numbers video and boy it really formed to his body

  • It still has his musk. It's lovely.

  • May I ask you a favor? Thank you. Here's two photos of me.

  • canyouspotthedifference.com

  • That game is a lot more difficult because those pictures of me that you just saw are

  • in two completely different locations, I'm not wearing the same outfit, and also one of them isn't me.

  • But spotsthedifference.com is a DONG, something you can do online now guys.

  • On stargazing you're given a map pinned with the best places to see the night

  • sky.

  • Each of these red stars has been designated as a good place to do so and clicking on one

  • gives you the information you need to check it out.

  • Some are observatories while others are just places where stars are more visible, like

  • Hatteras Island.

  • If Hatteras island is too far away just stargaze with

  • Online Planetarium where you can choose a location to view constellations from.

  • Granted, they aren't real photographs of stars but the benefit is you get to adjust

  • factors to your liking.

  • This includes time, date, and something called limiting magnitude.

  • For the naked eye this refers to the faintest stars that can be seen without the use of

  • tools like telescopes or cameras.

  • Now there are 88 official constellations

  • and the brightest ones are in the northern hemisphere.

  • The ones in the southern hemisphere are difficult to see just with the naked eye.

  • Each constellation has an alpha star which is the brightest out of the all the ones that

  • make it up.

  • For example, Delta Capricorni is the alpha star of Capricornus with an apparent magnitude

  • of 3.58.

  • There are factors that impair our ability to see the stars like higher humidity

  • and lower altitudes but the biggest factor of all is light pollution.

  • And to learn more about light pollution head to

  • Globeatnight.org.

  • The dots are color-coded based on limiting magnitude.

  • The higher it is the more light pollution there is and consequently less visibility.

  • To understand how light pollution can affect our ability to see here's a nifty little

  • infographic.

  • Obviously some light is necessary and that's this zone here but when it goes beyond what

  • it's supposed to light up it ultimately brightens the sky.

  • It not only harms this guy's “freakin' eyeballsbut it can affect other animals,

  • especially if they're nocturnal.

  • While predators use light to hunt species, their prey use darkness to cover up.

  • Light pollution also causes something called

  • Skyglow.

  • When the light on Earth reflects into the sky some of it escapes into space, but the

  • rest is scattered by molecules in the atmosphere.

  • This makes it more difficult to see the stars.

  • This is a beautiful scrolling experience and you'll learn skyglow facts along the way.

  • You can also interact with this map by scrolling from 1992-2025.

  • The site will also tell you the brightness by area in the year 2014.

  • A lumen is a measure of the total quantity of visible light emitted by a source.

  • Now Skyglow is thought to have a negative impact on people's health by contributing

  • to certain sleep disorders.

  • This can be because light can affect our melatonin levels which are responsible for when we sleep

  • and wake up.

  • Lack of sleep can be responsible for things like insomnia, depression, cardiovascular disease, and more.

  • It's hard to imagine a world without light pollution but there is a simulator just for that.

  • Light pollution is measured on the Bortle Scale which goes from 1 to 9.

  • Sliding it all the way to the left shows you the darkest skies.

  • Inner cities often measure a 9 and it makes stargazing much more difficult.

  • Of course this is a very simplistic simulation to demonstrate the effect of light pollution.

  • If you want to see what your home measures on the Bortle Scale there are maps for that.

  • This page gives you the key and then select from the maps down here.

  • In North America there's quite a bit of light pollution but not many areas where it's

  • a 9 on the scale.

  • Now let's go from light pollution to

  • Virtual Lighting Studio.

  • This is a great website for photographers or filmmakers and I actually really appreciate it.

  • You can choose among different kinds of lighting equipment to plan for a real life shoot!

  • Check out this handsome fella.

  • Click here to select the type of light you want to use like a ring light.

  • And ring lights are used by a lot of youtube creators.

  • It brightens the eyes while emitting soft enough light to decrease shadows.

  • And it's fun to play around with the position of the lighting.

  • Well, it's fun until you get to THIS.

  • You can adjust the intensity of the light you can add different color gels to it if you want to change the color temperature.

  • And you can even add multiple lights to your lighting setup and adjust their positions to get the look that you want.

  • Once you get the right lighting let's move from photographs to

  • Paintings.

  • Google Arts and Culture experiments have collected a plethora of art pieces from museums and

  • archives around the world.

  • Art Palette analyzed thousands of pieces and calculated their color palettes.

  • This site is cool because you can find art pieces by adjusting five different colors

  • to your liking.

  • It's curious to see what you can get because sometimes what would seem like a garish

  • color combination actually creates some awesome art.

  • If you want to see what pieces share a color scheme with something you created or photographed

  • you can do that right here.

  • And that's enough visual art so let's go to audio art with

  • RaveDJ where you can mashup any two youtube videos you like.

  • Let's try M83's Midnight City and the Barney Theme Song.

  • Oh yeah that's great what a work of art.

  • And if for some reason people don't like the music that you make well just take it away with you on

  • Island you created onDraw Your Island.”

  • First draw yourself.

  • Wow that looks exactly like me.

  • Now I'm gonna draw my best friend aka Michael Stevens, a campfire, smoke, and a pet taco.

  • And a fish I guess.

  • The list goes on but look at my island. Yay!

  • If you enjoyed these DONGs and you want to keep learning about the night sky then I would highly recommend checking out

  • the Astronomy course on Brilliant.org who was nice enough to sponsor this video and

  • Brilliant lines up really beautifully with what we're trying to do here at vsauce. They offer courses in science, math, problem-solving, and Astronomy.

  • So one such course is the Life Cycle of Stars.

  • It goes through star formation, stellar evolution, and black holes.

  • If you want to check out brilliant the first 36 people to click on that link at the top of the description

  • will get 20% off a premium annual subscription and they are lovely human beings over at brilliant and I'm really appreciative of them supporting Vsauce.

  • And also this chair. I get why Michael

  • likes this chair. It's very comfortable. You kind of just sink in a little bit.

  • Scooched. Ya know it's very nice. Also

  • fun fact about that prime number video.

  • Michael actually did it for 6 hours. We filmed it once

  • There was a problem. So then Michael and I came in on Saturday

  • and filmed it again so that is really good on you

  • Michael I'm very proud of you and if you want to tell Michael how proud you are

  • You can go follow his personal Twitter that not that many people I don't think really know about.

  • It's @I'mnotMichaelStevensJakePleaseDon'tEverPutThisInaVideoThatWouldTerrible.

  • That's his handle. Go let him know

  • that you really love him and appreciate all the DONGs that he brings into the world.

  • And I'm gonna go take off this sweater and beanie because I miscalculated how hot it would be today.

  • Especially in this hot studio. With all these hot lights. I'm gonna stop speaking. And as always, thanks for watching.

Oh why hello there! I'm Jake. I am sitting in Michael's
