The complicated names given to some stars, are often abbreviations of the institution/programs that photograph/register them - and then simply given a number. NGC are pretty common, for example - and stands for "New General Catalogue". Thousands of stars are named "NGC" followed by some number.
"I wonder why that star is white" Stars come in a spectrum of colors, mainly ranging from deep red/brown to white/blue. There are many factors at play but the short answer is temperature. Our sun's surface temperature is around 5800K. Sirius A's surface temp is around 10,000K, roughly twice as hot as our sun, and thus is more white in color.
In fact, even the Sun is white (the "yellow dwarf" definition is deceptive). Or, if we want analyze his spectrum and find out the frequency in which it emits the most, we should say it is green. Is not by chance that plants are green too.
That's why we cannot see green stars, we need to see them as White a neutral color so we can see the blue and red. because our eye evolved with the light frecuency of a green star, that's why plants reflects that color because they need to catch other colors less abundant and yellow green is the most abundant.
Interesting fact: The smallest known stars are only city sized (sometimes less than 30 miles across). These are neutron stars, which are what some huge stars collapse into being after they die.
The stars have colours depending on their surface temperature. Cooler stars have a reddish white glow while the hottest stars have a bluish-white glow. Red has a lower energy light particles than blue light, hence red is more present in cooler stars. When things get millions of degrees hot, they emit X-rays, like in neutron stars, black hole accretion discs, etc.
Yeah, just to make sure you understood, they numbers they are giving are not distances, but sizes in km. Remember, some of these objects they are showing are moons, planets and stars. The colors are a representation of their actual colors. Here are the reasons and classifications for stars: The color that a star appears depends mainly on the temperature that it burns at. More specifically, the color is directly related to the surface temperature of a star. In the lowest temperature range, stars appear in the red color family. At the highest temperatures, stars appear blue. Here is a list of the temperature ranges and the colors that you will see: Red - 3,000° - 6,000° Fahrenheit (1,649° - 3,316° Celsius): Type M Orange - 6,000° - 8,500° Fahrenheit (3,316° - 4,704° Celsius): Type K Yellow-White - 8,500° - 10,500° Fahrenheit (4,704° - 5,816° Celsius): Type G White - 10,500° - 13,000° Fahrenheit (5,816° - 7,204° Celsius): Type F White - 13,000° - 17,500° Fahrenheit (7,204° - 9,704° Celsius): Type A Blue-White - 17,500° - 50,000° Fahrenheit (9,704° - 27,760° Celsius): Type B Blue - 50,000° - 100,000° Fahrenheit (27,760° - 55,538° Celsius): Type O
Hi, nice reaction! :) That said: At the beginning you mentioned "Oh, they are showing the distance". That is wrong. They are showing the diameter of those planets and other space objects. Not their distance to earth. Greetings Mega
2:58 - *_Technically, our sun should have been white too in that presentation: While we see it as somewhat yellow, that is only because the Earth's atmosphere modifies it to appear yellowish, but it's light is actually white (So if you ever saw a sci-fi movie in which you see the sun from space as yellow, that was a mistake: It should have appeared white -Though many filmmakers, even if they know this, will still make it yellow because it is easier for the general public to recognize it as our sun that way). Stars like ours are called white dwarves_*
To answer your question on star colors, you can consider the colors to be a visible representation of their temperature -- brown and red are the coldest (still around 2,500-3,000°C) while white and blue are the hottest (anywhere between 7,500-50,000°C). The Sun falls in between these two ranges at around 5,300°C, so it's considered a yellow dwarf, though technically it's more white than yellow. What's interesting about yellow dwarfs is that they also output most of their light in green wavelengths with almost as much in red wavelengths. This gives the impression of yellow, but if we followed classification correctly, it would be a green dwarf! I believe "white dwarf" was also not chosen because that is a completely different type of star.
I was waiting for this reaction ❤ , universe size comparison. Proxima centouri is not a planet, it's the nearest star to earth after sun but still 4 light years away. The rest are some stars of various life stages and the red ones are red supergiants, the largest stars ever known. Uy scuti was considered as the largest but stephenson 2-18 holds the current record. It could fill upto Saturn's orbit if placed instead of sun in our solar system. The other are black hole , supermassive blackholes and nebulas are the birth stages of a star made up of cloud of gas , dust and light. Then the milky way and ic1001 is a supermassive galaxy and bootes void is an empty space where there are little or no galaxies.
Stars are different colors depending on their size, magnitude, and what elements are contained within the star. Depending on what material it’s burning and how much it has to go through results in the wide range of colors you saw in this video! (In fact when our sun dies it will actually be reduced to a much smaller red dwarf star.)
For a more digestible reference, UY Scuti is so big, if it were swapped out for our sun, it's surface would very nearly reach Neptune's orbit, and would swallow up every other planet closer than it.
The colors represent temperature of that star. Red is the coolest & Blue stars are the hottest. It goes Red, Orange, Yellow, White & Blue. Wolf Rayet Stars are by far the hottest. Space is mind blowing once you're actually able to wrap your mind around it. Our sun seems huge & in our corner of the universe it is. The Sun makes up 99.8% of all the mass in our solar system. There are other start out there that literally make it look like a light bulb. Stephenson 2-18 could fit 10 billion Sun's inside it.
Different composition and heat lead to the different colors of a star there is another video that shows the size of the observable universe also there is planet u think they recently found which is a diamond a big ass planet size diamond 😀
Hello Dasha! Love your reactions! Please do next this "Black Hole Comparison: th-cam.com/video/QgNDao7m41M/w-d-xo.html I have seen a lot of these celestial objects comparisons, and this is one of the most breathtaking. And talking about dramatic music...just WOW!
6:34 I'm the opposite. I lean in the direction of Neil deGrasse Tyson "Many people feel small because they're small and the universe is big, but I feel big. Because my atoms, came from those stars." From a video called "The most astounding fact" Should definitely check it out. I see it in the bigger scope, we are simply a cycle of life in a never ending process. Eventually... once our sun swells into a red dwarf in a few billion years, our planet will be consumed and explode. Sending our atoms back into space. And WE will become the creator, giving birth to the next forms of life. WE will usher in the next cycle in far away worlds,. Long after we are dead and gone. You may feel small, but it is where we come from, and will return to. We are all part of something larger than we will ever know. I know I will eventually find galaxies we will never reach in our lifetime. So that is why I don't feel small, or insignificant. Becoming a parent to those worlds someday, that is what brings me comfort, and why I don't fear death.

I never knew the Sun was that big, these videos always blow my mind, I was waiting for her to say Uranus is also beautiful, I would have lost it

Not distance. Diameter. Also, Promixa Centauri is a small star, not a burning planet :)
I love watching shows about the universe i watch them and history channels .
who else we're shock after Betelgeuse pop in😅😂.
I highly recommend you react to "TIMELAPSE OF THE FUTURE: A Journey to the End of Time". It's amazingly well made and will blow your mind

WOW WOW FANTASTIC😮
It's not the distance, it's the size! 😁✌🏼
@@WR-yc8ts I'm thinking it's the diameter, why would they go with the radius?

@@dddddddd4a I have no doubt that there is an infinite number of universes. However, most of those universes can probably not sustain life.

btw proxima centauri is a star

Dasha is dang cute it hurts
Fun fact: the sun is actually white not yellow
different suns burn different colors depend on their temperature, the white ones are much hotter than the yellow and the red ones.

Actually our star is actually white so idk why it's always perpetrate as yellow/orange.
