So much research must go into these videos - it really shows. Your videos are a joy to listen to, even when the topic can be pessimistic lol
He could do a video about broccoli and it would be cool lol
@Boco Corwin lol agreed them lil trees are delishhhhh
Agree with your opinion. Excellent science vid showing much research.
@Boco Corwin Brassicas are indeed an interesting topic. I may do one on them.

"You can call me a wishful thinker. But I'm a wishful thinker with reliable sources."
Nice one
Isn't that an appeal to authority fallacy?
@@abloogywoogywoo Not IMO. "Harvard scientist says" or "New study from Yale Medicine" is an appeal to authority. It is more of an appeal to the scientific method and citing your sources
@@avipuchalapalli The universe doesn't care about mankind's citations and references you understand?
@@abloogywoogywoo Do you have a better alternative to reliable sources?
@@avipuchalapalli Humans are fallible, and the universe incomprehensible, so I'm afraid not. You're trying to find order in chaos. I've long given up that crusade.
Until we get better data, I'm still part of the 'wait and see' group when it comes to rocky planets surrounding Red Dwarf stars. I very much appreciate you covering both sides of this, there is shockingly little well-studied presentations of the large ranges of possibilities of flare impacts on a variety of atmospheres. I have been saying for years if the flares can strip 3 atmospheres, all it takes is a planet with 4 atmospheres. Thanks as usual for your high quality content!
The data, the data, the data. Whether we get the data through larger, better adaptive, or more sensitive optics and sensors, or we have to build multi-gigawatt lasers to send solar sail probes on a 20-40 year one way mission, and wait as long for the return signals, we must get more data... Until then, it's all just unsubstantiated conjecture. Fun, but useless.
@Vision Thing Thank you, I will leave my physics faux pas up for all to see my fallibility, and observe your succinct and respectful correction, so demonstrative of proper and efficient internet ettiquette.
@@Gun4Freedom Nonsense. You are saying that we should wait decades before trying to study even the closest stars. That would mean the end of science and the triumph of pseudoscience.... which I suspect is your agenda.
@@davidhoward437 That's not what I said at all. What I am saying is that we NEED TO GET MORE DATA. There, is that clearer for you now? I am saying it needs to be prioritized! Not waited on.

Every video is the same for me: I say to myself, I gotta go to bed, no way I can watch 28 minutes. I'll just start it.
27 minutes later: WHAT?!??!! That's it? Come on Nick, I want mooore!!
Thank you for your poetic science videos! Whatever Proxima B is really like, it's sure to be stranger and more fascinating than we can currently imagine.
I love that you use "normal" pictures of the scientists involved. New fan!
You're still my favorite Proxima news outlet.
So glad to see you uploading more frequently mate. Also glad to see your last video got so many views.
Nick, you're killing it with these videos. Well researched, excellent narration, and easy to re-watch several times over :)
Great as always - just cheeky enough to keep things fun. And you really nailed it with 'means and opportunity' - hilarious. Keep 'em coming. I'm almost finished watching them all. And thank you.
Hello wonderful person.
Anton much?
Wrong show :)
@@296jacqi Someone had to say it !

Goddamnit... I couldn't help but read it in his voice...
As much as I dream of warp drives etc, now I just want colossal telescopes to bring them to us.
"A stars light shift caused by an orbiting companion." Finally a video with an answer. Most videos I have seen say they use the stars dimming as the planet transits the star. I've wondered how they know a planet caused the dim unless the star transits on a regular basis. Most planets would transit in multiple years if not tens or hundreds of years, so how do they find planets like Jupiter? They would only find large planets with short orbits. Now I know and understand. Thank you.
They can still find Jupiter-orbiting planets, if they look at enough stars. Sheer probability means that one of them would have to pass in front of their star eventually. But that's transits, not radial velocity, which is about detecting a wobble via redshift/blueshift.
Ive heard next to no information, not even theories, on the newly discovered proxima c.
How is there only 25,000 subscribers? Ha.... I say only. 25,000 is great but the quality of these videos deserves much more. Been on a binge of your videos. Really enjoying them.
I've been watching since this channel was under 10K, and it has deservedly grown so much since then. I think it will be at 100K before you know it.
So wait. The argument for ruling out massive rings around Proxima C is that the system is too old and they should've gone away by now, right? But you go on to say the evidence for that lies in Cassini showing Saturn's rings are only 100m years old and may last 100m more. So how exactly is that evidence that Proxima C rings shouldn't be there? If anything, the Cassini study shows the rings can appear anytime regardless of age of the star system.
The universe is under no obligation to abide any argument made for or against anything existing within it. There could exist conditions to keep an extended ring system in equilibrium for extremely long periods of time if there are shepherd moons, maybe moons that slowly shed geyser snow to replace the rings as they slowly lose mass. It could be a perfect Fourier Transform resonance between multiple shedding shepherd moons extending away from the planet, all gravitationally heating eachother, and will continue for the next billion years, if left undisturbed.
The hydrothermal vents spraying water ice from Enceledus, one of Saturn's moons, could be regenerating Saturn's rings. Indeed, this may be be their origin.
@@joshjones6072 It contributes, but probably not enough. That's why they'll disappear. Something massive, not as massive as the major moon, but quite big was obliterated/shredded to create those huge rings
The real question is how in the holy fk did they figure out the age of Saturns rings using some shtty flyby pics??
@@theprinceofallsaiyans5830 It has something to do with the rate at which ring material is falling into Saturn (called "ring rain"), how pure the materials are (almost 100% water ice with no dust) and simulation of course.
Also, I believe Cassini dove into the rings before burning up in Saturn's atmosphere and sampled the material there.
Now the challenge is to find a nifty astronomy backronym for “cappuccino.” 😜
> “Centauri Alpha and Proxima Planetary...”
As always, thanks ever so much for excellent video, Mr Ambassador! ⭐️
If I may, could you extend your credentials to the main binary stars of Alpha Centauri?
I’m curious about the exoplanets around there, especially since they’re G and K stars.
There was a hint of an exoplanet around A a while back, but apparently it's been retracted.
You've come a long way, and your doing a great job btw 👍🏾
When astronomers start experimenting with Petri dishes, things are getting interesting, exobiologically speaking.
Lets not also forget the whole pre main sequence potentail problem of red dwarf habitability.
I keep watching it, and it just keeps on getting better everytime.
This absolutely made my morning, thank you Nick. Revisiting the topic that first led me to your channel no less. Perfect.
This will very likely be the first alien system we send a probe to. The first exoplanets we photo close up. Let's be as optimistic as the shackles of data allow.
Sadly, I think Proxima B is a scorched rock. I hope I'm wrong though. If the nearest exoplanet turns out to have liquid water and an atmosphere I think it would bring forward practical interstellar travel by centuries.
Top shelf content my guy. Super interesting that I listened to the video a 2nd time. 👌
I’ve heard before of other discoveries made by going through old data, I love the fact that we live in an age where we have so many instruments receiving so much data that discoveries are just waiting in data centres to be discovered. Anyone going through the data can discover something as yet unseen . Wow .
Count me a Proxima B believer! And hey even if we're wrong, it'd still be neat to send a mission there to see how planets are up close in other star systems.
My question is, how in the hells did I not find your channel sooner? Dude you have such an amazing voice for that. ^^
I'm sure it's a good vid but I upvoted before watching because of the hilarious title
This is one of the few channels on RUclips where despite pretentious phraseology it's actually worth watching.
I love the phraseology (and keep in mind he's English), it's poetic. And if you think this is bad search for any paper by Tesla. Which has lots of beautiful written sentences, which are tough work for most today, yet it was very common for people to write like that back then (such as presidents speeches, kings, et al, all very flowery)
@@nicosmind3 People back then didn't dumb things down to be "accessible" except for children. The average person was expected to be intelligent enough to understand, while upper classes had less of a fixation on being "common."
Just starting this video and just the intro music is like a warm handshake and a friendly smile from an old friend, just before we head out to a bar, or off for a meal, and already i know im in for a good time :)

@@jennifersaar1611 Sure if you're a square
@@thetruth45678 I'll compromise - space beer bread.
A moon three times the mass of Mars? It depends on your definition, but if this is true then depending on your definition (I prefer a mass ratio definition to a barycenter definition), you could easily consider this a double planet/binary planet. At least a moon three times as massive as Mars is big enough to potentially be habitable in its own right (or another dead rock depending on your theory). That's an awesome possibility.
Ultimately, even without life on Proxima b, I hope it is an interesting active planet with an atmosphere and hydrological cycle. At least it seems that not all red dwarfs are so bad, as it is thought the Trappist-1 planets have thick atmospheres.
I'm still down for the trip, even if I die on the way and have to reproduce.
It seems possible that Proxima B''s heightened vulnerability to impacts works to its advantage. If flares blast away B's atmosphere or water, a bombardment from icy impacters could replenish its supply of volatiles. If we find a shockingly Earth-like Proxima B, I'd expect we'd have Proxima C's asteroid-shoving to thank.
The quick inserts are either a homework assignment for further exploration or a veiled bit of snark .. Cats ?!? Are all rabbit holes black? Interesting that the algorithm offered this to me just now. In terms of the other things on offer, it was no real contest. Suddenly and without a second thought, third went to first and subscribed. 😎
I think they're bookmarks to what was going on during the month and year noted
I'm riled up just from the title, down with proxima B!
That was really well done. Your audio is really top notch on this one. Thank you for the update.
I watched the whole 28 mins and I must say that this kinda videos need more views
I'm sure your comment helped the algorithm :)
I'm such a space geek.
I don't know why I didn't see this channel or the Proxima b. video.
But hey, it's never too late.
Now I can spend the rest of Covid-19 season by wondering around in this channel.
Something important not in the video, maybe ParallaxNick mentioned it in earlier installments of this topic but I can't remember, there's such a massive info dump on this (spectacular) channel:
Our sun has a huge churning buffer - let's call it a mantle, although it's technically known as radiative zone and convection zone - that absorbs most of the core's violent activity, protecting the surface (and therefore the surrounding planetary system) from receiving the brunt of a massive nuclear fusion reactor.
Meanwhile, due to its' size, a red dwarf has very little such space between its' core and surface, making it a nearly naked fusion reactor.
Put another way: When our sun's core has a tantrum, only a minuscule fraction reaches the surface. When Proxima's (admittedly smaller) core throws a tantrum, a majority of it reaches the surface.
Excellent presentation and content! My new go to for everything in depth astronomical.
Such a clever way to deliver a copious information dump.
You're subscribers are going up about 0.1 a day so 30000 subs video before Christmas
Can't go wrong with a little stellardrone
The title made me laugh.
I subscribed- keep these coming please.
Here we all are, drifting around - like puerulus - on an immense sea of curiousity, awaiting the favourable currents of Nick's next video to carry us toward the nutrient-rich waters of knowledge.
You know it makes sense.
Next one should be up in 3 days :-)
I've always wondered if the hunters depicted in the Predator series were supposed to have originated in a red dwarf system like Proxima since their vision seems to be in the infrared part of the spectrum.
Thank You, Nickolas.
Science, humor, and a tinge of philosophy. Great combo
That was fantastic, thanks very much. Even the music too 👍
Life always find a way maybe even in Proxima b
Syd Tacitus I agree, many scientists say that life is very rare in the universe but I don’t think so because life always finds a way
That statement could only ever be valid for our specific kind of life since that's the only kind we know to exist. Even so it's a typical case of survival bias because we only see and know life that found a way and we tend to ignore the countless times when it didn't find a way.
Ooh, new astronomy channel for me! Subscribed.
I hate to be a pessimist but I think we all know in the back of our mind its probably just a big rock.
It is just a bigger tidally locked mercury
The huge moon of proxima b likely induces a large tidal influence that generates a very strong electromagnetic dynamo
There is a terrible error with the subtitles at 24:35 that needs addressed! "Kelp ***gers"
The current subtitles are autogenerated by RUclips, not much he can do about it unless he were to type out his own subtitles, which is a pretty big undertaking, especially since he would need to re-transcode the video as well.
@@lordofentropy telling RUclips people about it wouldn't hurt.
They are not 'subtitles'. They are a machine-AI reproduction of the audio rendered into letters. They are pretty much useless and unreliable. Ignore them.
Why? It is what it is, unless some word there has some POWER?
@@hillaryclinton2415 apparently it does because my comment with the word was deleted, now unless you have something to actually contribute, please, kick rocks.

“The Carl Sagan Institute, a place I would work at merely on principle...”
You and I both brother.
This is a huge problem, actually. You have talented graduate students battling, winning and losing, for terrible grants. People are working almost for free and they're not even necessarily the best for the job, just the most cutthroat. Sad but true.
I love the entire Proxima system!
there is Good news now: K- and M- red dwarves don't shoot their flares out at planets from the equatorial region of the star...the flares shoot out from the polar and tundra regions (or what would be tundra on a planet)
If life evolved on a world around a flare star, it could be expected to be highly resistant to Gamma Ray Bursts that would wipe out all its immediate neighbors.
I needed this trip
NICK I THINK YOU ARE BRILLIANTLY EASY TO UNDERSTAND AND FOLLOW.

you relesing a video makes me super happy and excited
I love your narration so much
wow i know nothing about this but its so exiting i had to click like button
It makes you wonder how many other discoveries are sitting there in 'dusty' data, overlooked because the search parameters were too narrow or the researchers were looking for something else.
I would bet the farm we know a whole lot less about these planets than we know... which is probably somewhere between nothing and next to nothing.
@Peter Mortensen Is your neighbor's house next to your house? Can you stand between them? ;)
@19:06 "... however yeasty." Got it.
Awesome content. Beautifully spoken.
I am intrigued by proxima starsystem
If a planet is tidally locked to an active star is the side facing away from the star protected from the activity of the star?
How microscopic have our conditions been to let us evolve into todays human beings. I can only feel an enormous empty black wall approaching us, briefly saving us a breath before it anihilates us into empty careless background radiation. No grave or memory. Only space.. and dull time..
"A moon three times the mass of Mars" um probably no, more likely a closer in 3rd exo-planet, for fun I tried simulating that in universe sandbox with it being a moon on a 5 day orbit, it didn't work.
Superb content on Proxima and its planets. I will read every peer reviewed paper you cited. It's very hard to find a complete overview of the current understanding of Proxima Cen star system. Thanks.
Btw, the hydrothermal vents spraying water ice from Enceledus, one of Saturn's moons, could be regenerating Saturn's rings. Indeed, this may be be their origin.
If so, a perhaps larger Enceledus-like moon of Proxima C could be generating a very large ring system around that planet. While a gas giant ring system might only last millions of years, such a moon could be active for billions of years, being acted upon by tidal forces from its large gravitational partner.
Proxima B knows what Proxima B did. Proxima B is well aware that it got what it had coming to it and aint got nothing to complain about.
@Peter Mortensen But I wont because clearly you are an asinine dick arguing about irrelevant minutiae .
I wrote what I wrote and I wrote it exactly as I wanted it.
Your such an amazing story teller! You have a great voice.
Thank you for another great adventure in our wonderful cosmos!
I wish I could talk or even tell a story that would keep anyone let alone everyone spellbound!
As well as you do.
Thank you again. Your so awesome! 😊
Maybe once JW goes up we know more. Yes its a flare star but we have no idea how the solar system is set up. Still exciting to see things breakthrough starshot.
25:47 I'm wondering if the James Webb telescope would be of any help for this. Of course that's assuming it's not eternally a money hole, 2 years from launch.
The 'Theory of Relativity' must be true: Every hates their nearest neighbor on Earth, and apparently the same applies to the nearest stars as well.
What Proxima b turns out to be, may do a lot to shift our calculations on the likelihood of habitable, or life-conducive conditions around red dwarfs. If it turns out to be barren rock without an atmosphere, then that fact, alongside with the observation of AU Microscopii makes it hard to be optimistic about the chances of any terrestrial planet around a red dwarf.
If, however, Proxima b turns out to have a relatively thick atmosphere, that would be a hopeful sign; it might mean that life on planets around red dwarfs may not be that unlikely, and that AU Microscopii was an outlier, or represents the evolution of only some red giant systems, rather than the norm.
So the observation of Proxima b, if and when it happens, seems to me, could be very consequential, one way or the other.
Stephen Baxter's 2013 novel, Proxima, has a fascinating depiction of a biosphere.
However, I am ready for the line from Aliens (1986); "It's a rock. No indigenous life."
Well, it's not like LV-426 wasn't interesting...
It's probably a desert world but has underground lifeforms. Has anyone checked for live around Alpha Cen A and B? They're more sun like? The binary very close to Proxima, that is.
"...visible to the naked eye" dang, where was I at that moment?
Why havent we tried to put satelite telescopes around say Mars to look out into space.
thank you this was excellent.
Maybe a little greenhouse gas effect on earth isn't so bad after all for when our sun becomes unstable.
I wonder how often you've played Sid Meier's Alpha Centauri. (And just imagined it to be Proxima Centauri instead.)
What can be done to minimize flairs? Dump a bunch of hydrogen on it?
Question: any update on the possibility of Alpha Centauri Bb and even Alpha Centauri Ab?
Fukin love your videos, brooooo!
We've already found transiting red dwarf worlds in ridiculously tight orbits that still possess an atmosphere, albeit one clearly streaming away and roasting at thousands of degrees.
The fact that these worlds still have an atmosphere thick enough for us to see gives hope to Proxima b, at its much safer distance.
There's also its gravity. It's at least as large as Earth. That gives it a far better chance of holding gasses than Mars, as well as internal sources of replenishment for CO2 through volcanism.
