A Tour of Alpha Centauri

- In humanity's search for life outside our Solar System, one of the best places to look is Alpha Centauri, a system containing the three nearest stars beyond the Sun.
A new study that has involved monitoring of Alpha Centauri for more than a decade by NASA's Chandra X-ray Observatory provides encouraging news about one key aspect of planetary habitability. It indicates that any planets orbiting the two brightest stars in the Alpha Cen system are likely not being pummeled by large amounts of X-ray radiation from their host stars.
Alpha Centauri is a triple star system located just over four light years, or about 25 trillion miles, from Earth. While this is a large distance in terrestrial terms, it is three times closer than the next nearest Sun-like star.
The stars in the Alpha Centauri system include a pair called "A" and "B," that we'll call AB, which orbit relatively close to each other. Alpha Cen A is a near twin of our Sun in almost every way, including age, while Alpha Cen B is somewhat smaller and dimmer but still quite similar to the Sun. The third member, Alpha Cen C (also known as Proxima), is a much smaller red dwarf star that travels around the AB pair in a much larger orbit that takes it more than 10 thousand times farther from the AB pair than the Earth-Sun distance. Proxima currently holds the title of the nearest star to Earth, although AB is a very close second.
The Chandra data reveal that the prospects for life in terms of current X-ray bombardment are actually better around Alpha Cen A than for the Sun, and Alpha Cen B fares only slightly worse. Proxima, on the other hand, is a type of active red dwarf star known to frequently send out dangerous flares of X-ray radiation, and is likely hostile to life. - Věda a technologie
i like to think their is something in physics we have not yet discovered that will allow us to get there in a human life time.
The Bad Guys Warp Bubble. 10 times the speed of light. Be to Alpha Centauri in 2 weeks.
StarShot or SolarSails.
It’s nice to have hope
Well, the experts declared man could not fly, but we did. The experts declared it was impossible to go faster than the speed of sound, but we did. They said we could never go to the moon. The experts have been wrong before.
Chances are that’s the case
The universe is so massive and ripe for exploration, sadly our species is too busy fighting ourselves.
Imagine if all humanity came together to work for the better good, we would have lived on Mars years before
@@vujiciclinus3551 That a true fact.
Don't forget the universe is still expanding faster than the speed of light.
It’s infinite as far as we know
Even if we could travel at 50% the speed of light, we'd get there in 8 years. I really want to see this happen.
Well we can't. If you leave now, you will arrive in about a century.
Edit: More like your copse will arrive there.
Edit 2: Or maybe the other astronauts will throw your body out the rear of the spaceship hurtling back towards earth.
Edit 3: I find it hard to believe humans can fly through space for a 100 years that doesn't end in a explosion. Somebody is bound to have an opps moment during that period.
@@debaterofeverythingpresent2775 what am i missing here
Lol wouldn't you age slower in space n im.sure you would age diffrent on a diffrent planet
the nearest star in Alpha Centauri is only 4 light years away. scientists believe the journey could take 20 - 25 years If humans ever do end up going in the future.
@h Indeed. But we'd have to send a colony there, since coming back would not be a viable option. The crew would have to go there and stay there.
I wish I wasn't born when touch screen phone came out
I should have been born when Mars was colonized
@Jeffrey Kelley also NASA is broke
Elon San will leads us to victory
Jeffrey Kelley Illuminati is fake dipshit
you need to appericiate earth for what it is
Gaming with kary cryogenic freezing
Her voice us so smooth and emotionless. It's like a sci-fi film with a vast intelligence holding humanity captive.
Her voice actually gave me a boner.
She is reading, and she don't know reading. That's all.
Wow...thats excessively descriptive...
Wish people could forget about all the pety shit on earth and work together on discovering space.
@aiecky _ he means the fight over resources and religion should end. If we manage to achieve peace and prosperity on earth then we could colonize the solar system and start our journey to the nearest stars.
@1GoldRunner are racists really the worst of humanity, I mean do they really trump the rapists and the murderers
Seconded a world government should have formed years ago to slowly start colonizing Mars
Millions already are. Check out Sirius Disclosure.
Limited by space...
Who’s here 2020 from Lost in Space
LOL
WOW yeah
Meh
Me
Yeah, I didn’t think Alpha sentari was real tbh
This was where the Robinson's were headed to... back in 1965 till...they got..."LOST IN SPACE"...🛰
Billy Matthews ...I knew I had heard about that star somewhere before!
This is the whole reason i watched this video. Cuz of lost in space
Thanks to the clumsy Dr. Zachary Smith, the Robinsons never made it there.
Alpha Centauri is the nearest star system of earth after sun. How did the Robinsons get lost in between earth and Alpha Centauri in another star system?
@@enigma19able that's the mistry in show
the distances involved are just mindblowing...and these Stars are close by. I quite like thinking about all this, puts your life into perspective
Rob Wilkinson, I agree!
Unless we build a warp drive, it wouldn't be feasible to travel beyond our solar system.
I hate thinking about it, realizing how ridiculously far away anything from our single solar system is and that reaching anything out there is probably impossible.
Its too sad that we with our current understanding of space will never be able to travel between stars. To find life on another star system would be the greatest achievement in human history. Hope someday someone's brain will spit out an idea that will give us hope to travel between the stars.
When do we get in our jupiters? Xd who love lost in space?
Meeee
Me “danger will Robinson “ We die together we live together
sab ._. hi bruh the finale season is coming 2021 omg allready
Lost in space make us to find a new human habitable planet
Meee bruh
Lady, from where I’m sitting the entire universe seems pretty damn hostile to life.
Because we don't know much, we think our hole is the best
Correct we don't know their could be an civilization in Centauri System
Was it just me or did people come here from good omens...?
the yeet boi suh dude👈🤠👈
No wonder Crowley wants to take his boyfriend there
We really should explore this system in the future.It's fascinating to learn about how a tri star system function
Awesome little video !!! Simple, short, and yet, comprehensive and objective.... Congratulations to the channel !! 👍👍
There has to be other life out there even if it’s microscopic life it still counts
It is, or it will be on Mars, but somewhere in the universe is a life like here.
Bramborak I’m sure there is but the messed up part is that it’s almost impossible to find the universe is so big even traveling at the speed of light it’s still far hopefully one day In the future
Yes. BUT there are planets that NASA thinks has greens in it (probably grass) grass are alive. So have we found life?
ThatOneBread that’s considered plant life and most likely if there’s plant life there’s other life maybe “earthworms” for example
The aliens are real. Governments wouldn’t admit to it in the past but they are getting ready to reveal them soon.
Always worth watching. Thank you!
Human hasn’t even land in to Mars
And there already thinking going to alpha Centauri
Silly hooman
They've already been there and know about it the truth will ALWAYS be hidden by humans so long as the "adversary" keeps people in fear and hate
@@elijahslade1133 oooo I like the creativity- you may not be able to substantiate your comment much - HOWEVER research on mars has exhumed data that shows curious concentrations of Xenon in mars' atmosphere- which has only been recorded on earth after large nuclear detonations. Something strange occured on mars. Also alpha centauri is relatively close by to our solar system and has shown to have multiple planets around it- very cool maybe we are connected to other species from the galaxy or beyond. People who think outside the box in a peaceful manner should think about that more often.
Dude i'm tired of these Aliens posing as humans and talking smack online
@@mattyice2099 theres great evidence to suggest what you say about mars is true...some artifacts can be seen on the planet and i dont believe they are all just rocks.i think something happened there a little while ago and maybe we are the martians after all...
There's so much to be learned from Alpha Centauri. The biggest factor will be if any planets have arisen around either of the two inner stars. On paper, their minimum separation could still allow for a stable planetary system around each on the scale of our inner Solar worlds. But can one even develop, given the gravitational interplay between two mid-mass main sequence suns? We still have a lot to learn about accretion dynamics under such conditions. This is important because multi-stellar arrangements like this are more the rule than the exception. From Proxima, we can learn how planets can form and evolve around red dwarf suns. The ubiquity of such stars and the demonstrated fact that they possess planets makes this knowledge important as well. Any future civilization capable of interstellar travel will need to know about their options in dealing with what they're liable to find.
We are already as far out in space as we could get. So thats pretty cool too.
Actually Dr.Smith is nice. And i love penny
@@CaptAngryEyes June Harris *
What if she still alive in ss 3
I hope we find some more interesting planets in orbit around these stars.
Amazing info about Centauri A!
Thank you
Thank you very much. Exciting information.

Me want season3 on Netflix
Very interesting !
A fellow student in my speech 101 course mentioned that he was Alpha centurion and sounded pretty convincing like k-pax. This was back in 2004.
Great images ...
Wow i love science
Nice
XD
i need a cure for aging so i can live there
Hey
Your home suns
Merci
Who's here from Netflix: LOST IN SPACE
Very nice
Good omens brought me here
Janine TheQueen same buddy
This is a good video. Thank you. This video also proves that a real human voice is more effective and more efficient than a synthetic robotic voice.
What's the skiing like?
By three times closer do you mean one third as far ? # times 4 light years was 12 liggt years last time I used a computer to calculate it for me. That is further as far a I can determine.
If you haven't seen it yet I highly recommend Passengers it charts out a path for a spaceship to reach Alpha B
Jarak yang ditempuh sungguh sangat menakjubkan
Been nice if the Jupiter 2 made it there as intended to finalize the series. I want the goal to reach there if all the squibbling countries put the finance from war to development of eventually finding a way to get there.
When men solve other here and now social/nature important matters here in Earth, then I believe would be cool to explore and humanity would be ready to do that. Just observing the mess here, would be sad to take all that messed up into the outer space eventually.🤔🙂
How good it will be if we can contact and see more in details the interstellar objects thru telescope
Thanks for the tour, but I missed the gift shop and the restrooms.
You also missed the restaurant and the kids facepainting
But what are the prospects for stable planetary systems around the two inner stars?
They'd have to be very close in. Incidentally, a candidate signal for a small gas giant in Alpha Cen A's habitable zone has been detected since you wrote your comment.
Please give some more information about these stars 👍👌👌
nice video
After Lost In Space Season 2 (NETFLIX) 2020... From India 🇮🇳
I can't imagine with so many galaxies in the universe, that we are the only sole life forms to dwell a planet. What makes us so special?
nothing , obviously we are not the only life since they discovered there was life on Mars early on . 100% proof and mainstream not conspiracy theory . Inteligence is another matter but life in general it's plenty I think
4 light years. Traveling 4 years at the speed of light.
" We can run away together! Alpha Centauri! "
Crowley
There must be other civilizations in that star system.
What most don't think is we are in space. Just on the surface. Traveling along the galaxies edge. Yes the solar system we exist in travels. When you lay on the ground, look up at the night sky- away from lights- you can easily see much more and realize/marvel at how much there is to see- and thats a microscopic amount compared to all else, I don't see how anyone can believe there is no other life elsewhere.
Is this where xandar is located?
We have had encounters in our past human history. It is not abput fly8ng discs, but about the likelyhood of encounters....they are much closee then we think.
You're looking at our own early solar system, literally. The Sun, proto Jupiter and Proto Saturn. Jupiter and Saturn both give rise to life, quite different life, the purple dawn story tells of the Saturnian early days of life. Judging by the the point in the past we are seeing, it is likely incorrect that it is less than 5 light years away.
Random question: About how many AU would you have to be from our sun in order to look at it without any eye protection or special filters so as to not risk damage to your eyes? Like could you look at it from one of the moons of Jupiter? Or Pluto? Or would you have to go much farther?
Lukeamania beyond pluto
also at the edge of the solar system you need protection
What about where Voyager 1 is right now? If I was aboard it, would I be able to look back at the sun without going blind?
@@mawage666 You would have been alone in space for 41 years to discover this by yourself...
@@eilonj Yeah I wouldn't have been able to go with. The thing was 2 years out by the time I was born lol.
'Just keep pickin' 'em up, and puttin' 'em down' - that's what I always say.
1:50 to 1:53 in -- Wow! Proxima Centauri's orbit around Alpha & Beta Centauri "takes it ten thousand times further than the Earth-Sun distance" -- that's 10,000 AU, or only 1/27th the distance of our Sun to Proxima Centauri itself.
forestsoceansmusic it’s still huge for an orbit.
@forestsoceansmusic And that is extremely tiny compared to the vast size of the Galaxy which itself is a tiny piece of the Universe as we know it
yes
It's all majestic. And then there's Hutton Orbital
I hear they have free Anacondas there.
ELITE DANGEROUS
@Joshua Dela Fuente Yes. Hutton Orbital... part of an online game called Elite Dangerous...
Hutton Orbital is an Outpost located in the Alpha Centauri system. It orbits Eden, which orbits the star Proxima Centauri.
Hutton Orbital is notorious for being extremely far from the system's hyperspace jump arrival point at Alpha Centauri A. The distance is 6,784,404 ls, or 0.22 ly.
Hutton Orbital is the home of two rare commodities: Centauri Mega Gin and the The Hutton Mug.
Great video. We just published an interview with Nobel Laureate Dider Queloz where he talks about the most realistic way to 'explore' Alpha Centauri.
This is scary to find out but the way we are going now I doubt we are going to get there anytime soon
anyone knows any free website to learn about space. comment plz
i love plantes like this
Its a star not a planet
What do we learn again?
You think they got hoth out there?
Fun fact: Chandra means Moon in Hindi!
Its becoz respect and honour in memory of Great Indian Astronomer Subramaniyan Chandhrashekhar.
What's funny in that
Any body, I have a proposition.
You know what... first things first... I was just like you 6 months ago. I hated so called racists and Nazis. I wanted them all to just fucking die.
But one day, someone leaves a comment just like this one. They give me a few places to look. Well, me being a curious person listened to their calls to do the research objectively. What I found has changed me forever. I am pretty fucking mad about how bad I was lied too, and now know the truth about many things the elites do not want us to know. I will now leave at your feet the offer someone else once offered me. Be warned though, my friend. Once you learn this information, you will feel a burden and a weight lifted off at the same time.

Direct links get me shadowbanned. Most people, i assume take these random offers I give out a few times a week or 2 , and either ignore them or scoff at them... I understand, that for most, those who own the media , have done such a good job at mass indoctrination, that this attempt is futile... but there are gems... It is those gems I have tried to reach that last few months. This is all I will say though... A saying about leading a horse to water most definitely pertains to this situation...Good luck on whichever pill you decide to take... Hopefully the indoctrination isn't too deep.
nobody cares
@@delltawnnorthri7459 Piss off, clown and get yourself a life.
Imagine being from that solar system and hearing all of their creation stories and gods and what name would they call their suns? And what constellations do they see?
I was hoping to view an animated model of the orbits of the stars and the exoplanet and how they all interact with one another as well as time frames for orbits. Does anyone know of a link to something like that? Thanks.
We aren't even sure where the planets are
You didn't make clear whether there were exoplanets in the habitable zone found orbiting A or B or whether the binary orbits would even support stable orbits...
They should've added the link to press release.

astronation Thank you for sharing that. Interesting to see that the jury is still out on exoplanets because of the orbits.
Water. What's your point?
Exactly
thats what I was waiting for too...the video could have been longer but NASA is on a tight budget
TRUCK DRIVER’S JOURNEY THROUGH TIME AND SPACE In September of 1979. A truck driver named Harry Joe Turner claimed to have had a UFO encounter that left him unable to work and seeking psychiatric and neurological help. He had only partial use of the left side of his body after the incident.“Ever since it all began,” Turner said, “I’ve just been sitting here going over and over it in my mind, trying to piece things back together. I’d feel pretty good if I could just figure out where I’ve been.”Turner said that he was willing to talk publicly about the incident in the hope that someone had had a similar experience and could explain it all to him.Turner was driving his truck from Winchester to Fredericksburg, an 80-mile trip he had never made before. It was raining, and he said the road was strangely deserted. He saw the lights of an approaching truck in the distance.“And from that moment on,” he said, “it was like I walked through a door right there into another world.”Turner saw a brilliant light shining in his rearview mirror, then a beam of “palpably thick white light” settled over the truck. The steering wheel no longer seemed to control the vehicle. The entire truck was floating and an unknown “being” opened Turner’s cab door while another one was heard on his roof. He felt extreme pain in his shoulder, which he said was the steel-hard grip of one of the beings, though whoever the creature was, it was invisible. He reached for his revolver and fired where he believed the creature to be, getting off eight rounds, which seemed to simply pass through the being without harming it. When he realized he couldn’t kill the being, he panicked and his consciousness simply faded out.
Turner says his next memory was of waking up in the warehouse parking lot in Fredericksburg with no idea how he had gotten there. He was on the passenger side of the truck, and the seat belt on the driver’s side was fastened. His watch read 11:17, but a clock at the warehouse said it was 3 A.M. Most curious was that two mileage indicators on the truck showed that the vehicle had traveled only 17 miles since leaving Winchester. He unloaded his truck and rushed home to Winchester.As is often the case with alien abduction, details of his otherworldly voyage began to come back to Turner. He said that his captors dressed in white, like doctors, with white caps on their head. When the beings lifted their caps, numbers written across their foreheads became visible. The words “Alpha Centauri” floated into his mind, which the reporter, Bill McKelway, points out is a star 4.3 light years from Earth, but which Turner had never heard of before.“He felt he had been taken to a city-like place 2.5 light years beyond the star,” McKelway writes, “and there was a stop on the moon where he viewed astronaut Neil Armstrong’s footprints.”The city Turner described seemed to have suffered a nuclear holocaust, and it was the mission of the aliens to prevent a similar occurrence on Earth.“They want to help us,” Turner explained, “but they say things have gone pretty far here and that the end is coming soon.”As he tried to put his life together after the first incident, Turner was visited by a band of six of the Ultra-Terrestrials. The creatures were again invisible but he believes he was able to knock five of them to the ground. On another occasion, he left the house and returned soaking wet for no apparent reason, probably another example of the “missing time” phenomenon he had experienced on his ill-fated trip to Fredericksburg.The strange after-effects continued. He had crying spells and sometimes animals reacted strangely in his presence. Once he was out driving only to find one of the Ultra-Terrestrials in the car with him. Spurred on by the creature, he led as many as ten law enforcement officers on a wild chase through Berryville and Clark County at speeds exceeding 110 miles per hour. He was eventually stopped by a policeman and charged with two counts of reckless driving and two counts of failing to heed a siren and flashing lights. At the time the article was written, Turner was scheduled to stand trial in a couple of months and “his defense undoubtedly will be the most unusual in the history of Clark County General District Court,” according to McKelway.In the meantime, Turner struggled with suicidal thoughts, a ringing in his ears, and with the warning messages he continued to receive from the Ultra-Terrestrials. He also read the Bible frequently to find some kind of sense of meaning.“Many years from now,” Turner said, “I’ll still probably never know what happened that night.”

Then constant updates will eventually be 4 yr old data.
