Having it be on Pluto makes zero fucking sense. Ya'll can go back and rewatch the video if you want, but all you'll find is confirmation I was right.

The temperature is proportional to the color and brightness. The hotter the star, the more it shifts to higher frequencies of light like white and blue, and the brighter it gets.

The more massive the star the faster it burns fuel because it has more gravitational pressure and thus fusing elements faster. Some of the earliest stars in the universe were very short lived because they were so massive that they just burned through fuel like crazy and died with extreme amounts of passion and thus created some way crazier stuff outside of helium. It’s pretty cool.

"What's Ceres?" Ceres is/was the biggest asteroid in the solar system; after the international community reclassified the definition of several celestial bodies (when they decided to open the category of "dwarf planet" and "downgrade" Pluto there), Ceres and other dozen massive asteroids were reclassified there. When this video was done, Ceres was still the biggest asteroid and a common reference about the size of things in our cosmic neighborhood. "Probes sent to Venus" Yep, you might reffer to the Venera the first (russian) space program; that tried to research Venus. Since the probes were sent to first discover the conditions on the planet, they weren't designed to what they found: a planet suffering of a super greenhouse effect due to a lot of volcanic activity; temperatures in the athmosphere are some of the most extreme in the solar system and the probe could only transmit for some moments before being fried. "Neptune is a beautiful looking planet" Indeed. In the matter of records, Neptune holds the strongest winds in the Solar System: on average they have been calculated around 1126 km/h, and maximum limits of 1931 km/h. Oh! And it's suspected that in this unstable planet you'd something like a rain of diamonds; the models consider that the chemicals that form Neptune (a gas planet) at some depth can break releasing enough carbon molecules, that would turn into diamonds due to the same presure :P. Then, as they get deeper to areas with more pressure and temperature, they'd be vaporized, float back up in the insides of the planet, cool down, form the original chemicals again and sink (once again) to start the whole diamond creation/destruction process again. "Proxima Centauri" Proxima Centauri is the closest star to our sun. Only in the category of "stars", not to be confused with "the closest exoplanet" or "the closest galaxy" to us. "Why stars are fo different colors and the sun is yellow?" Fun fact: the sun isn't yellow; in general it's white(ish). We have colored our sun yellow for generation because our atmosphere filters and refracts most of the light the sun produces except the red/orange/yellow tones; but if we saw it outside of earth, it wouldn't have any tonality. Stars do have an associated color, though, depending on their age, and it's kind of an indication of how the fusion processes inside them are going. In short, young "hot" stars have a color that goes from blue to white, teen "warm" stars go from white to orange (in this classification, our sun is between a white and yellow star, right somewhere along the middle of its life expectancy) and old "cold" stars go from orange to red (and are some of the most massive objects in the universe). As stars get older and run out of their natural fuel, they grow in size and change their color. "How different nebulas form?" Well, such beautiful and massive objects are a balance between disaster and gravity. Some nebulas formed after the death of stars (basically, when massive stars explode); the shape they form will only depend on the force of the blast, and the gravity that keeps the remanining elements togheter. And from those nebulas, elements mix to give birth to new stars and planets, starting thar process all over again. "What's Omega Centauri?" That's a globular cluster; for centuries thought to be a star, due to its brightness (in dark places, it's visible to the naked eye). But in reality, it's a stacked collection of 10 million stars orbiting around one point, not just one massive star. It's been proposed this cluster is what remains of a dwarf galaxy that collided and was swallowed by our galaxy: the Milky Way.

6:00 Being formed from a supernova is definitely a good educated guess and is indeed how some nebulae were formed, but there are of course different methods of formation other than this. For this particular Helix Nebula it is a planetary nebula which are formed from stars of 0.8 to 8 solar masses shedding most of their outer layers after expansion near the end of their life, and eventually reaches a point where its outer temperature is high enough to ionize the expelled gases with ultraviolet photons causing the glow of the nebula.

2 things that I think no one mentioned: Proxima B is the closest exoplanet. As far as I know, we haven't named planets outside of our solar system, so we name them "star+alphabet letter" starting with the B (the star would be considered the "A" component of the system). For instance, on Proxima Centauri we know Proxima B and Proxima C, althoug C is too far and not really to much interest on it. But that's probably your cofusion, specially since Proxima Centauri it's actually called "Alpha Centauri C", because it's a part of a 3-star system that also has an A and B. About stars, after this video we discovered a bigger star than UY Scuti called Stehpenson 2-18. If both were put in place of the sun, UY Scuti would engulf all planets and go a bit past Jupiter, while Stephenson would go all the way past Saturn.

Ceres (the first object on the scale) is the largest known “asteroid” in our solar system. It’s technically classified as a dwarf planet and exists in a stable orbit between mars and Jupiter.

UY Scuti is such a massive star but to put it in perspective on how big. UY Scuti is about 750 million miles or almost eight astronomical units. If the star were placed at the center of our solar system, it would extend far beyond the orbit of Jupiter, closer to the orbit of Saturn. It is absolutely nuts to think a star could be that freaking huge!

1:37 There were multiple probes sent to venus and they (after venera 7 who lasted 29 minutes only in freefall due to the immense storms and sulfuric acid rain) died in i think it was around the 50 to 60 minute marker (venera 9), they were russian probes and they were made specifically to be as sturdy as possible, they also took pictures of the service and captured multiple sound samples. The only reason they died so fast was due to the heavy storms of venus and the temperature being extremely high (it is extremely hot (820 degrees to nearly 900 degrees F or around 475 degrees Celsius being hot enough to melt lead), the air pressure is extremely high, there are very strong winds, sulfuric acid rain (at higher altitudes) and lightning storms driven by volcanic eruptions). Also funfact venera means venus in russian.

The colour of stars depends on the surface temperature (and the star's movement speed in comparison to us (because of lightwave speed compression, or whatever it is called)).

To me the amazing part is when they switch to light years. Our closet star is Alpha Centari. And yes some nebula are formed by supernovas. Just imagine if alpha exploded, it's only 4 light years away. Pretty damn close

Proxima Centauri is a Red Dwarf or M-type star, and yes, Proxima B is one of the planets that orbit that star, and it's in its habitable zone.

defenitely something I need to refresh my memory upon - iirc these are the steps when suns are dying - first they turn into a red giant and then shrink into a white dwarf - but it is at least a decade ago now that I learned that once - have to find my old books again ;/ mfg Olli

7:57 That's just a picture of the microwave background! From when the universe turned from opaque to transparent, gamma radiation was released. Over the eons, due to the expansion of the universe it has been redshifted into the microwave spectrum, it now corresponds to thermal radiation of an object that is 2,7 K hot. (or rather, cold)

The expanding Universe was a explenation back then, because we cant explain why almost every Galaxy is moving away in such a high speed, expansion also explains why certain objects move with lightspeed wich is not possible otherwise. There is also a black hole called, the great attarctor, its quite big and seems to affect a lot of galaxys.

Omega Centauri is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677. Located at a distance of 17,090 light-years, it is the largest-known globular cluster in the Milky Way at a diameter of roughly 150 light-years. Sorry quick Google cause I also was like hmmm not seen that before. Yea there is many things you need to learn brother but liked and subscribed regardless

Best teacher ever

Star color is based on temperature

The more hotter the more brighter and the more it changes the colour of the wavelength

Our Sun light is actually white (you can see that in pictures taken in Space), the Earth's Atmosphere filters out the blue hues, so we see it more yellow-is. At Sundawn/Dusk Sunlight has to go through more Atmosphere to reach your eyes, and even more blue is filtered out, hence it turns dark yellow, orange and red.

8:06 the universe doesn’t actually expand, it’s more like the “universe” is already infinite, but all the galaxies inside it are moving outwards and away from each other 👍 Eventually if humans survive long enough, people will grow up without knowing what a star is

I think the more heat a star radiates the more it moves into the Blue Spectrum while passing through the Colors Red, Green and Blue (mostly all three at the same time) which would cause the stars to appear white, because all three "main colors" of the light Spectrum create combined white light

Vega is an F-type star, it is white because it has a higher temperature and luminosity than our sun, it even burns faster, so it has a shorter lifespan.

The void has about 60 galaxies in it. Thats like finding only 60 I-phones in the entirety of the USA, meaning no trees, grass, mountains, pebles, cars, people, homes. Absolutely nothing except for 60 iphones.

Answering the question about why the stars have different colors, if I remember correctly, its very dependent on the temperature they burn at, the cooler stars are towards the color red, and the hottest are blue

When a star is blue, its because about the heat. There is an scale, where you can see, which temputere, shows which colors. And nice video! Really cool reaction! I love the universe bymself and its always amazing, when they discover new things in it! Like, unbelivable things :)

The reason why stars can be different colors is because of the temperature, the hotter the star the more blue it is and a cooler star will appear more red

You should react to the universe size comparison in 3d it's got way more stuff in it

And our sun is actually rainbow, but we can only see orange, yellow and white because they are the strongest and other colors go on the other side

I’m assuming you only know mid secondary school level physics so about the different colours of stars, different temperatures emit different wavelengths of light, you can look up the exact temperature to wavelength ratio but basically the hotter the star is the brighter it is and what colour it is, it roughly goes, black, red, orange, yellow, white, blue ( our sun is a yellow dwarf star with a surface temperature of 5500 degrees celcius, Rigel is a blue giant star with a surface temperature of 30,000 degrees celcius

In terms of star size you have dwarf stars, giant stars, supergiant stars and hyper giant stars. And then you have the phases, where you have, giant, supergiant and hyper giant sizes ontop of the predetermined class

stars are different colors based off of their heat output which is determined by the size.

the portion of the universe that we can currently observe, is estimated to have a radius of about 46.6 billion light-years. This measurement takes into account the expansion of space over time.

6:43 globular cluster, structure with stars merged and held together by gravity

Yes, larger stars are more massive meaning the cores are compressed more resulting in faster burning.

I am surprised that the Hercules-Corona Borealis Great Wall was not on that list that thing is massive and defies known thinking of structure

Just some stuff: The first planet named ceres is pronounced seiries, our sun is yellow hence the name yellow dwarf yet the light emitted is actually white, the white stars are named white giants because of their size, and the red stars like betelgeuse are named red giants, red super giants, and variable stars.

probably like 10 people have already explained but the reason stars are different colors is because of their temperature. Think of it like a campfire. When you start the fire it starts off a dim red. Keep it on and it becomes like a bright red. If you increase the temperature it will become orange and then yellow. Once you get past yellow, you get white, and as you get hotter and hotter, you get blue. Stars are (sort of) the same way. This isn’t the best explanation I just wanted ro say because I’m a huge nerd about this kind of stuff

More Geography now ! Professor Michael

The Sun is called a Main Sequence star, Rigel is a blue white Supergiant star and Betelgeuse is a red Supergiant Star. Rigel is a lot hotter than Betelgeuse, but Blue Supergiants are not as big as Red Supergiants. There is a lot of info to take in concerning stars.

A, B, C etc are denominations for planets. The size of the black holes should worry you, because a star has a TINY FRACTION of the mass of a same-size black hole. These things rip holes into space-time, literally. There is a legitimate universe simulation tool where you can visualize so many amazing things from our universe. It's called *Space Engine.*

Ceres is one of the main dwarf planets as well as make-make, haumea, Eris, and Pluto

Arcturus is an Orange Giant Star located 37 light-years from our solar system in the constellation of Bootes.

Ceres is one of the many dwarf planets in our solar system. It´s main call for fame is being larger than Pluto. One of the main reasons why we don´t call Pluto a plaet anymore as we would need to call Ceres a planet too, as we would need for a few others that are as large or nearly as large as pluto too.

The giant white bright stars are also main secret stars but they are of a different spectral type for, instance, Sirius A star is an A0 or an A1 spectral type whereas Vega star is an A0V spectral type the different shades and colors of the stars just simply means that particular star is in a different stage of its life. Another example would be our sun. In about 5 billion years, the Sun is due to turn into a red giant. The core of the star will shrink, but its outer layers will expand out to the orbit of Mars, engulfing our planet in the process. If it's even still there.

4:00 color depends on temperature, it’s like you melting metal it becomes red, then yellow then white, similar stuff

One of the coolest yet most scary thing about the end of our universe isn't to me that the speed will reverse back into another big bang like a breath and then create a new big bacg... nor the speeding up for the planets, suns etc from their orgin of the big bang creating a void that makes any possible way of making contact or going to other planets impossible... it's the third one for me (I remember it being called "the giant rift") and basically it's that the speed of the 2nd one where the planets and suns goes further and further away from the origin of the big bang in such a speed after a while where it begins to affect the smaller particles down to an atom level and ripping everything apart... good to know is that the planets and suns would be ripped long before that -but the theory is interesting as F! :)

The Boötes Void(colloquially referred to as the Great Nothing) is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing very few galaxies, hence its name. It is enormous, with a radius of 62 megaparsecs.

a nebula forms when a ⭐️ goes supernova

Testiment to human education: "Where do these nebulae come from? I dunno. It looks like a supernova. Like, it exploded a long time ago, and this is what's left. But I dont know. Someone educate me!" Dude knows enough to understand the basic functions of the creation of stars, as off-hand knowledge. Freaking ordinary, everyday knowledge today that would have totally baffled anyone from 50 to 50000 years ago. Go education!

There can be stars of all different colors. The sun is actually white. It's just the ozone layer messing with your eyes and the extreme amounts of light, but stars can be all different types. The color can depend on how big it is or what kind is.

There is an updated one "universe size comparison 2020"

5:57 dying star throws away her layers of gas making those beautiful structures (there are some made by supernova explosions, but they look like circle around white dwarf)

Ceres is the smallest dwarf planet, located in the asteroid belt 3:35 it is because of temperature, because if you have a candle ant light it, it gets blue on the bottom(if no chemistry is used)

ok so voids are not spaces where there is absolutely nothing. The contain galaxies as well. But the density of galaxies is very low. Basically if you zoom out enough, you can see the universe organize into strands of galaxy clusters called the cosmic web. Voids are the 'empty' spaces between. But it is not empty. it's just... emptier.

Sirius A is also known as the "Dog Star" it's also twice the size of our sun, and it's natural color is blueish-white, it's an A-type Star and it's only 8.6 light-years aways.

There's 3 theory (at least that I know of) about how our universe might end up : the Big Crunch, the Big Rip and the Big Freeze. The Big Crunch is the one about how the universe will one day suddenly collapse on itself, like a reverse Big Bang. Though, like you said, it is becoming less and less believed given the observations made about how the universe is constantly expanding faster. The Big Rip is the one where the expansion of the universe will reach a point where everything within it will be ripped apart on an atomic level because the forces at play are simply stretched thin. The Big Freeze is about how the universe will one day run out of heat and thus, everything will freeze in it which is what, I think, is currently believed is happening. Either way, it's gonna suck for those who are alive when it happens : either you suddenly get compressed back into an uniform mass with everything else in a moment or you end up being ripped apart on a scale that means you'd die in utter confusion of what's happening or you'd survive a slow, long process through which you end up freezing gradually until there's no heat left for motion and everything becomes a standstill. At least the Big Crunch would mean another universe would be born of it... the other two, not so much.

the bootes void is the largest void in the known universe but they are not entirely empty.

Proxima Centauri is a star in the Alpha Centauri star system (its Alpha Centauri C) and has three known exoplanets, Proxima Centauri b,c and d. B is the only one that is within the habitable zone (it's also earth-sized, has earth like mass, is likely tidally locked), as c is way too far out and d far to close to its star, thereby being each too cold and too hot. Alpha Centauri A is rumored to have a habitable planet, however that has yet to be confirmed, and Alpha Centauri B allegedly has one, it was "found" in 2012, but it was agreed that it most likely doesn't exist, so yeah, you're right, it was indeed Proxima Centauri that has a habitable planet.

As a star's temperature increases, as a result of there being more gas in the star - and hence more fuel to burn - it becomes hotter. Its colour changes from orange, through yellow, to white. The hottest stars are blue, with temperatures up to 40,000ºC.

Ceres is a dwarf planet in the asteroid belt Venus’s atmosphere is carbon dioxide which is why the satellite burn up it is also super dense Proxima Centauri is the closest star to the solar system (about 4.24 light years) it does have exoplanet orbiting it Luminosity depends on how bright a star is

I really love your videos

A Harry Evett video, Venus has crushing pressures, any space craft that lands...good for 10mn.

The color of a star depends on its temperature, if the star is yellow, then its temperature is most likely 500 degrees. and if white, then most likely tens of thousands of degrees

The sun is actually glowing white when you go to space

Different Solar mechanisms burn different kinds of fuel. The brighter the shade, the more of that fuel it burns. Not all Solar bodies burn hydrogen. Some burn helium, etc. The larger the solar body, the quicker it burns through the fuel. What’s really interesting are Magnetars. Instead of the natural occurring neutron body being formed, they became excessively magnetic.

Fun fact the sun will be about the size of betelguese and its size will extend past Mars before dying. Vy canis Majoris extends past Saturn. 2nd Fun fact: It takes light 4 1/2 hours to reach neptune. Which means that Vy Canis Majoris is under 4 light hours big. So somethign like the Helix Nebula would be 18 x 365 = 6570 times larger than VY canis Majoris star.

'Why are some of the stars white?' The Sun is actually white too, it just looks yellow/orange/red to us, because its light passes through our atmosphere. But it is actually emitting pure bright white light.

Ceres is a dwarf planet in the asteroid belt.

1. The sun is actually white, (no idea why they made it yellow) 2. The largest start in the universe is Stephenson 2-18 (the second largest is UY Scuti, followed by VY Canis Majoris and Betelgeuse 3. Stars are so far away that when you look at them you actually looking at them from 700 years ago, if you want to see what the stars look like now you would have to wait 700 years until at that time you would see what they used to look like now. If Betelgeuse when supernova, exploded and disappeared right now, although it’s already non existent the star would still be visible from earth for 700 years even if non existent because it takes time for light to travel from there to earth and takes same amount of time for darkness to travel. 4. Black holes can also form from stars going supernova 5. Beyond our universe there are lots of other universes, it’s a never ending realm, you can travel in any direction for ever and ever and never stop, it’s infinite, space has no walls and no end because if it did space an end or walls then space would be all white light because the pre would be walls for light to reflect and bounce off of but there reason why it’s all black is because there is no such walls or boundaries, light just keeps travelling on and on for ever and ever. 6. any human could even spend their whole lifespan from birth to death travelling through space the whole entire time and still would be nowhere near these big stars, it takes millions of years and even billions, if including the whole universe then it’s infinity, all infinite, it’s never ending you couldn’t possible put a number to it, when something is infinite and never ending in any way no one can ever put a number to it, number of distance. It’s so big it’s impossible 7. Black holes can bend light, warp time and even create whole new voids inside of them, once you’re in a black hole there is no way of even getting out

Also, no, just because the star is big does not mean it's at the end of its life. Different stars have different lifetime expectancy. Is some big stars like you are scooby are actually just babies and way way younger than the sun.

2:53 it is the closest star to us after the sun and this star is just is 4 light years away from earth!

Me late but anyway. The stars' colors are mainly defined by it's mass (dwarfs, big, giants), temperature (over 5 273 kelvins is considered a main star if,....→) material (is hydrogen, Helium,...), and by it's age (a dwarf can die or born, or a giant can explode and become a dwarf or a black hole with a supernova explosion). And so.

Cool, Michael! Yes, the bigger stars burn out faster.
