The Brightest Stars In the Universe
Vložit

- There are countless stars that we can see in our night sky, and all of them are unique. Some are dim such that they are barely visible without a telescope. Others are bright and can be seen even in the most light-polluted areas. The brightness of a star depends on its composition and its location relative to our planet.
----
1- Sirius, All stars shine but none do it like Sirius, the brightest star in the night sky. Aptly named, Sirius comes from the Greek word Seirius, meaning, "searing" or "scorching." Blazing at a magnitude of minus 1.42, it's twice as bright as any star in our sky besides the Sun.
Sirius resides in the constellation Canis Major, the Big Dog, and is commonly called the Dog Star. In ancient Greece the dawn rising of Sirius marked the hottest part of summer-the season's "dog days."
2- Canopus, Canopus resides in the constellation Carina, the Keel. Carina is one of three modern-day constellations that once formed the ancient constellation of Argo Navis, named for the ship Jason and the Argonauts sailed in to search for the Golden Fleece. Two other constellations form the sail (Vela) and the stern (Puppis). In modern odysseys, spacecraft like Voyager 2 used the light from Canopus to orient themselves in the sea of space.
Canopus is a true powerhouse. Its brilliance is due more to its great luminosity than its proximity.
3- Alpha Centauri, Alpha Centauri (or Rigel Kentaurus, as it is also known) is actually a system of three stars gravitationally bound together. The two main stars are Alpha Centauri A and Alpha Centauri B. The tiniest star in the system is Alpha Centauri C, a red dwarf. The Alpha Centauri system is a special one. At an average distance from us of 4.3 light-years, these stars are our nearest known stellar neighbors. Centauri A and B are remarkably Sun-like, with Centauri A a near twin of the Sun (both are yellow G stars).
4- Arcturus, Arcturus is the brightest star in the northern celestial hemisphere. (The first three stars on this list are actually in the southern celestial sphere, though seasonally they are visible from the northern hemisphere of Earth). Known as the Bear Watcher, Arcturus follows Ursa Major, the Great Bear, around the north celestial pole.
5- Vega, The name Vega comes from the Arabic word for "swooping eagle" or "vulture." Vega is the luminary of Lyra, the Harp, a small but prominent constellation that is home to the Ring Nebula (M57) and the star Epsilon Lyrae. The ring is a luminous shell of gas resembling a smoke ring or a doughnut that was ejected from an old star. Epsilon Lyrae appears to the naked eye as a double star, but through a small telescope you can see that each of the two individual stars is itself a double! Epsilon Lyrae is popularly known as the "double double."
6- Capella, Capella is the primary star in the constellation Auriga (the Charioteer), and the brightest star near to the north celestial pole. Capella is actually a fascinating star system of four stars: two similar class-G yellow-giant stars and a pair of much fainter red-dwarf stars.
7- Rigel, On the western heel of Orion, the Hunter, rests brilliant Rigel. In myth, Rigel marks the spot where Scorpio, the Scorpion, stung Orion after a brief but fierce battle. Its Arabic name means the Foot. Rigel is a multiple-star system. The brighter component, Rigel A, is a blue supergiant that shines a remarkable 40,000 times stronger than the Sun! Although it's 775 light-years distant, its light shines bright in our evening skies, at magnitude 0.12.
8- Procyon, Procyon resides in the small constellation of Canis Minor, the Little Dog. The constellation symbolizes the smaller of Orion's two hunting dogs (the other is, of course, Canis Major). The word procyon is Greek for "before the dog," for in the northern hemisphere, Procyon announces the rise of Sirius, the Dog Star.
9- Achernar, Achernar is derived from the Arabic phrase meaning "the end of the river," an appropriate name for a star that marks the southernmost flow of the constellation Eridanus, the River. Achernar is the hottest star on this list.
10- Betelgeuse, Don't let Betelgeuse's ranking as the tenth-brightest star in the sky fool you. Its distance-430 light-years-hides the true scale of this supergiant.

9:06 correct in the captions, but narration says oxygen instead of hydrogen.
I caught that too, I was like wait, what?
however, in high mass stars
en.wikipedia.org/wiki/Oxygen-burning_process
The oxygen-burning process is a set of nuclear fusion reactions that take place in massive stars that have used up the lighter elements in their cores. Oxygen-burning is preceded by the neon-burning process and succeeded by the silicon-burning process. As the neon-burning process ends, the core of the star contracts and heats until it reaches the ignition temperature for oxygen burning. Oxygen burning reactions are similar to those of carbon burning; however, they must occur at higher temperatures and densities due to the larger Coulomb barrier of oxygen. Oxygen in the core ignites in the temperature range of (1.5-2.6)×109 K[1] and in the density range of (2.6-6.7)×109 g/cm3.[2] The principal reactions are given below,[3][4] where the branching ratios assume that the deuteron channel is open (at high temperatures)

thanks for the correction Chris, sorry about that!
@@AnalogDude_ - Nicely done. Maybe they'll get it....maybe they won't.
@@InsaneCuriosity Maybe correct that.
It's truly amazing just to think how far stars are away from earth but, when I look at them from my backyard, they seem like they're only a touch away. Truly amazing.
Hard science delivered by TV voice-over personality. A winning combination 👍
Keep it Curious ;)!
Spectacular! Thank you guys! 👏🏻👏🏻👏🏻
Thank You for watching! Curious people like you are our inspiration every time :)
Why the fu*k did I think it was a good idea to look directly at our sun while listening to this video 👀☀️
Can't even imagine stars twice as bright as our sun. Let alone hundreds of times brighter. .
Thanks for the great content 👍
It's important to keep being Curious in different ways ;) Thank You for watching!!
I'd love a video about dwarf planets sedna & Eris !!! ❤️
You never hear much about them, just pluto and Ceres , wouldnt mind if they were all involved and it became an entire dwarf planets video, but I have yet to find a video of just Eris or sedna facts that was worth watching.
I never request anything on any channel but I love this channel and believe it'd be a good idea!!
ERis: czcams.com/video/c2WOf4Ws4AA/video.html there you go!
And Sedna is coming soon!
I'm new to your channel but so far you're doing a fantastic job
Our pleasure and duty to keep your Curiosity up! :)
How do you figure there doing a great job? They aren't doing a good job cause they think our galaxy is the entire universe. I mean if your going to use Universe in your thumb nail, I would expect to see not just stars from our galaxy. The truth is, if you were talking about Universe, none of these stars listed would make the list.
I'm in Tanzania and I think i saw the Enif star on oct 8 saturday evening sky 2022. It is the brightest star in constellation pegasus and is easily viewable to the naked eye from earth.
Great video by the way. Amazing commentary.
heavy info here!!! had to watch like 6 times!!!!!
We definitely do our best to keep it simple and digestible! Thanks for your feedback we'll keep working on that!
@@insanecuriosity2682 no its not that is jard to understand is just there a lot to digest, i understood everything, but as i said had to watch like 6 times cause its really good!!!!!!
@@deflekt Awesome!! Glad you liked it and found it interesting! We take seriously enhancing Curiosity! :) Thanks for watching
1:36 Hipparchus using a telescope which was invented only in 1608. Well, nice drawing anyway...
thats what i was just thinking
Thanks a mill
Feedback; when you mention the star and discussing, please have the following in the background so that we can follow what you are saying. The name of the star, which constellation, luminosity of the star and please the distance from earth in light years. Also, if any one of these stars are out of our milky way galaxy (highly unlikely since all documented stars are still in milky way), please mention their parent galaxy. Thanks
What do you mean? These are all from our galaxy. Look it up. They think our galaxy is the universe. The truth is if they were talking about the universe, none of these stars would make the top 100
1:34 How Hipparchus(2000 years ago) is shown with a telescope in the drawing which was itself invented in 1600s by Hand Lippershey snd Galileo Galelei?
Perhaps he had one , but it was reinvented in the 17th century!!!!
But, seriously, I doubt that. Back then though, they were already using lenses to magnify things like writing and small objects.
In Holy Quran Surah Tariq - (Brightest Star)🌟
Allah takes Oath of Mighty Star.
Whenever Allah takes an oath in the Quran, what is to follow, is supposed to be something very significant.
Here, in surah Tariq, Allah swears by the sky, and by At-Tariq. Tariq literally refers to something that comes at night.
and here Allah specifies it to be a star. soem mufassireen say it refers to the biggest star in the universe which is many many times greater than even the sun.
After the oath, Allah tells us there is is someone watching over us, every one of us.
Allah Himself is taking care of us, each one of us, and has sent His angels for that purpose.
Allah Himself is looking over whatever all of us are doing and He has placed angels that are recording it.
So when the night comes, for some of us some days, hurtful memories and scary thoughts haunt us, anxiey takes over us, pain starts to numb us. Worry starts to eat us up. And while you're up late at night, studying for that exam thinking you're so screwed, remember He is taking care of you and your affairs. While you're up late at night doing that cumbersome project or assignment, and you feel so done. remember He is taking care of you helping you do all of it. When you're up crying over pain and injustice, and worrying over your life, remember who has all of it in His control. The one who controls the impeccable flawless systems of the worlds seen and unseen to us; who controls the planets and stars, the galaxies, the systems, we know and don't even know of, is the One taking care of this little you۔
🙏🏼
Anyone heard of alvo centaur and the black?
The list starts at 07:27. Thank me later.
Thank you, u saved a bunch of my time
@@hairband7395 you are welcome
So little time, so many errors...Tell me, was Hipparchus's telescope a refractor or a reflector?
Would be a Refractor since the reflecting telescope was invented in the 17th century, by Isaac Newton.
We are happy to solve any other error you perceived! Thanks for watching :)
Sirius A is the brightest star, and other stars are bright, and some are dimmer.
How about the new largest star ever discovered.. can you explain it
Stephenson 2-18?
@@vijaystanleymed6335 We can definitely take that into account for another video, thanks for watching!
That's because that star is in a different galaxy, and according to there list, only our galaxy is the only one in the universe. Know I'm only going by their thumbnail logic.
Do these guys know that the Univers doesn't only exist in our galaxy? Cause the last time I checked, every star listed here comes from our galaxy. If we are talking about Universe, none of these stars would make even the top 1000 most luminous stars.
do you know where i can find this list
@@anthony-qw2fi Well, since it is said there are about 200 billion galaxies, and in each galaxy about 200 billion stars, the chances that there are millions of stars brighter than the few we can examine is overwhelming
So the Brightest Star in the Galaxy is Kolob
Okay
Brightest stars in day and night is:
Day-Sun (Our star)
Night-Sirius (dog star)
I'm I right?
Definitely when the Sun comes down, as we mention "early in the evening" so technically yes, you are right!
I thought we could only see stars in the milky way galaxy
Yes, with the naked eye, but we can also see the andromeda galaxy with the naked eye too.
@@themousethatroared3371 I'm talking about actual stars not galaxies
@@cbeasley2578
Then yes. 😊
Not quite. Depends on your definition of "
seeing". With a regular optical telescope yes it's true. However, telescopes like the one in Chile (Very large telescope type) can use radiations (infrared and microwaves) to see even further.
If you wannna check more:
en.wikipedia.org/wiki/Atacama_Large_Millimeter_Array en.wikipedia.org/wiki/Very_Large_Telescope
Also, if it's about the naked eye, we can still see a bit more: starchild.gsfc.nasa.gov/docs/StarChild/questions/question15.html
Sirius is definitely brightest star in night sky ...... But R136a1 is brightest known star in the universe
About 8.7 million times brighter than our sun
What about vega?
@@BeingAshiq vega is brightest in north constellation in night sky. It is 5 th brightest star in night sky and only 60 times brighter than our sun
So basically R136a1 is still winner
@@BeingAshiq R136a1 is 150,000 times more luminous than Vega. Vega is 40 times more luminous than our Sun, R136a1 is 6 MILLION times more luminous.
1:15 the scale is LAGORITHMIC? Y’all need to catch this stuff. It’s embarassing. I mean you clearly do your research because the information is on point but your narrator is either overworked or not trying hard enough.
Thanks for the feedback Joe, will definitely work on that! Thanks for watching!
So its really THAT important that the dude pronounced a word wrong?? Youve never done that, correct???
@@herbertlong3981 not on a science CZcams channel with a pretty widely-known word, no.
Less intro pls
Agreed
noted, thanks
@@InsaneCuriosity awesome sauce!😊
Stephenson 2-18 is the brightest star
Stephenson 2-18 is the BIGGEST star (currently - it changes all the time as measurements are refined, and other starts are observed closely enough to guesstimate the size) known, not the brightest. Its Luminosity is estimated at only ~430k times the Sun's. R136a1 (Tarantula nebula in the LMC) is the most luminous star currently known, with an estimated Luminosity of ~6 million times that of the Sun, more than 10 times more luminous than Stephenson 2-18. Interestingly, to me at least, the 2nd most luminous star is only 5000AU - thats 0.08ly - away from R136a1, and is imaginatively known as R136a2.
The brightest stars that ever existed, are long gone and because the radiation from the Big Bang, obscures them, we will never see them.✨
@@darthvader1793 What's the question?
Actually we would never see them because more than likely they are just too far away to see!
@@herbertlong3981 In space distance and time are linked.
@@julianaylor4351 And your comment is in response to what? It certainly does in any way not pertain to that comment I made a half hour ago......
@@herbertlong3981 Troll.
These aren't the brightest stars in the universe, they are nowhere near.
Agreed. These are the brightest stars "as seen in Earth's sky", not "in the universe".
Yeah, I think these folks think that our galaxy exists in its own universe.
Do you think that someone made your house, even though you have never seen them? The house is the evidence of the builder. Same with this universe. It had a beginning, therefore it had to have a cause. And that cause, is God. This universe could not have created itself.
So do you think God cares about how we live? If He has given us morality so that we have set up a system of law with courts and judges, how much more would the supreme ruler of the universe demand justice?
Have you ever lied, stolen the smallest thing or thought a rude thought? If these were the things God would judge us by, would He find us innocent or guilty? The answer? Guilty. Sinning against an infinite authority figure brings infinite punishment. Hell.
So how can we stop going to hell? Does doing good deeds take away our sins? If I get a speeding ticket in the morning, then do 5 good things, should the judge let me go free? No, the fine has to be paid.
What about asking for forgiveness? If a criminal stands before a judge and says, I'm really sorry... Should the judge let him go free? No, because that would be a bad judge. If he forgave every criminal because he loved them, that would not be doing justice. Justice has to be paid. God is merciful, but not so at the expense of justice.
The only way we can go to heaven is if someone pays our hell punishment for us. Jesus lived a perfect sinless life and then took all of God's wrath for our sins upon Himself on the cross. Since Jesus paid 100% of our sins, there is none left for us to pay. Our punishment has been paid and we get off free. Justice has been paid and Gods mercy has been
upheld.
Our good deeds don't save us. Nor do they contribute anything to our salvation. Jesus paid it all. Just acknowledge your sins, and accept this gift of Jesus Christ to go to
heaven.
To learn more about God. Read the Bible. It's available free online. Read the gospel of John first.
If believing in some woo-woo magic being in the sky makes you feel better, more power to you. But don't push it onto other people please.
@@yumyong3847 trying to get people to think things theough. If you don't believe in God, you have to believe something (the universe) materialised out of pure nothing by nothing happening. That's believing in magic.
@16.15 No No.. it is called "Betelgeuse" NOT Beetle Juice... What's wrong with some people? You called it what it is spelled like not what some twat miss-spelled it as! Do you call the Pole Star Poolaris No you say it as it is spelled.. Polaris. I do Amateur Astronomy and have done it since 1990.. I really pisses me off some commentators and even Professional Astronomers miss say the official names of stars.. You would think they of all people would say it correctly? Not miss spell or say it totally wrong.
We understand your concerns, your comments will be taken into an account! Thanks for the feedback and for watching!
You forgot the most blaring error of all. That none of these stars would make the list if we are going by their thumbnail. Cause last time I checked, every one of these stars are in our galaxy, and our galaxy is not the only galaxy in the entire fricken *Universe* They aren't that smart though, and it seems as though, alot of orher people on here, aren't either. That's probably their target demographic anyway.
So whats wrong with YOU??? That star is actually pronounced "beetlejuice". You might actually look it up in a dictionary.
Is it not pronounced RYE-jull, not RYE-gull?
It only took me 1:55 to find two inexcusable errors. I stopped there, what a trash channel, whomever made this should be ashamed.
We will be happy to listen to those mistakes you found so we can keep working and getting better. Thanks for the feedback and we hope you can give other videos a new chance!
Being a bit anal, are you????
Blah blah blah blah, who cares?
You obviously cared enough to spend time commenting on it ...
Very boring..
Stay at the shallow end of the pool then, -- "Peeman" 🤣😂
Boring
Sorry it was not you expected, we are always open to suggetions!
Okay
