Finally! Exciting Planet Found Only 6 Light Years Away From Earth (Barnard's Star)

[@2nostromo]

I remember Pieter van de Kamp who published a series of papers throughout the 1960-70s claiming that the slight perturbations in the motion of Barnard's Star indicated the presence of a planet, or perhaps more than one. He estimated that this planet would be roughly 1.6 times the mass of Jupiter. These findings were significant at the time because they represented one of the first serious claims of a planet outside our solar system.

Barnard's Star was a destination for an early starship in Robert A. Heinlein's 1956 novel, "Time For The Stars." Telepathic twins communicate with earth as 12 ships explore in all directions. Due to time dilation, the twin on the ship has adventures and stays young as the twin on earth ages. Good stuff!!

Some recent data on M-dwarf flares. "A 2021 study lead by Ekaterina Ilin (Leibniz Institute for Astrophysics Potsdam, Germany) presented evidence that M dwarf flares tend to emanate from their polar regions, possibly sparing close in planets from direct hits. Their initial data was taken from a small sampling of M dwarf stars from TESS observations, and further studies showed that this may well be the norm." (from Universe Today 8/7/21)

[@douglaswilkinson5700]

Stellar flares accelerate charged particles -- protons & electrons -- which produces EM radiation -- usually X-rays and UV. If the flare is energetic enough gamma rays can be produced. The EM radiation produced by flares radiates in all directions i.e. spherically.

[@SpaceImplorerExplorerImplorer]

@@LuisAldamiz Quite a bold claim to make given your tiny sample size. Ever heard of the Sagan standard? Stellar flares are not exclusive around the poles. While they are ten times more powerful there, Barnard's star, for example, has the ability to destroy 90 earth atmospheres per billion years at the distance to Barnard's star's habitable zone. Even in the best case scenario, it is unlikely therefore that this specific planet is habitable. Same applies for Proxima Centauri b and other planets orbiting flare stars. Also, people who say that certain planets are unlikely to be habitable were never doomsayers.

[@tkermi]

@@LuisAldamiz I think you got the speed incorrect. If you are referring to similar sounding NASA project (can be found by searching: "Extreme Solar Sailing for Breakthrough Space Exploration") its estimated goal is to reach 1000 AU distance in 20 years. I don't know how much the sail would add to the velocity after that, but I'm guessing not huge amounts that far out. So if just roughly calculating from that result it would mean 6 light years distance would take about 7600 years, lol. In reality it would take less since meantioned maximum speed is planned to be 0,1% c. But still over 6000 years travel.

Have you seen what happens near the core? We have footage. If radiation doesn't get you, some random star will get flung towards your system, distrupting everything. And nothing says life can't do great at the edge of a galaxy, but with the little amount of matter there, it would be difficult for star systems to form in the first place. So really, I don't know where the discussion is coming from. Everything requires certain parameters in order to exist, and life is fragile.

Among the known stars, Proxima Centauri has been the closest to the Sun for about 32,000 years and will be so for about another 25,000 years. It is currently 4.24 ly (1.30 pc) away. A 2014 study predicted its closest approach to us as 3.07 ly (0.94 pc) in roughly 26,710 years. Alpha Centauri is a double star. The pair is around 4.34 ly (1.33 pc) from us. Barnard's Star is 5.96 ly (1.82 pc) away, so it is at the moment the fourth closest known star. It's closest approach of 3.75 ly will be around 11,800 CE, that is 9800 years from now. But Proxima Centauri stays ahead in the race to be closest to us, until 25,000 years from now when the lead passes to Alpha Centauri. Which one of the double will be closest depends on where they are in their orbit around each other. They will take turns being the closest. These numbers are from Wikipedia Nov 15, 2024.

Not proposing this as even a hypothesis, more of just an idea. Considering the apparent age of Barnard's Star, and it's motion across the heavens, I suspect it is reasonable to consider it likely to be a star that was ejected from a globular cluster as that merged with the Milky Way Galaxy, in an event similar to what Captain's Star went through. The idea is that in that interaction, any gas giant planets in the system which may have been in outer orbits because of the age of the system (assumed) may have been imparted with vectors that did not allow those planets to stay with the star as it traveled on a new trajectory. Those planets may now be Stephen Wolf planets, may not be part of the composite that is the MIlky Way, and so we end up with just the small collection of terrestrial planets that were sufficiently within the gravitational well of the star that they went along with the star on it's current trajectory. Again, I don't think this qualifies as a hypothesis. Testing it would have to include attempting to work out it's path through the galaxy with enough resolution to determine if we can identify possible globular clusters that it may be from. And that's still going to be a 'Maybe' unless there is enough evidence in spectrographic information to tie it to one or another of those clusters. (I'm not going to hold my breath waiting for such results.)

[@simonshack1]

I posted the below comment a couple of days ago but it now seems to have been removed. Thanks for letting it stay, Anton! 🙂 Marvellous news indeed: thanks to the European Southern Observatory, Pieter Van de Kamp is - at long last - finally vindicated. Back in the 60’s, Van de Kamp had detected two bodies / companions around Barnard’s star and argued for decades that it was a binary system. Yet, he was derided and scoffed at during his entire life by his peers, some of whom even suggested that what he’d seen was due to the “improper cleaning of his telescope lenses”! Now, Van de Kamp’s estimates of the masses and periods of his two bodies may have been incorrect, but given his limited means, I think we can forgive him for that. The point being that Barnard’s star is clearly not a single star - but has most likely a binary companion (somewhat akin to Sirius B - the tiny binary companion of Sirius A, the brightest star in our skies). So we have had to wait until October 2024 to find out that our second-nearmost star has a bunch of companions! And as Anton points out at 2:09 in this video, two bodies were discovered (only a few years ago) around our very NEARMOST star, Proxima Centauri (one of them extremely similar to our planet Earth). Well, if it has taken so long to find these companions of our two nearmost stars, it is quite reasonable to assume that 100% of the stars have companions - and that NO ‘single stars’ exist in the universe. In my 320-page book (“The TYCHOS - Our Geoaxial Binary System” / 2023) I briefly review in Chapter 2 the bitter and long-lasting feud between Van de Kamp and Wulff Heintz - a top expert in binary stars who vigorously rejected Van de Kamp’s findings. Why so - you may ask? Well, here’s the thing: the growing realization that ALL (i.e. 100%) of the stars in our skies are ‘locked’ in binary systems is scaring the wits out of the mainstream astronomy community. Since our Sun is still believed to be a single / non-binary star, the heliocentric paradigm would instantly and utterly fall apart - out of sheer statistical logic - if it were ultimately discovered and admitted that 100% of our surrounding star systems are binary. In my TYCHOS model I demonstrate that Mars is the Sun’s binary companion, much like Sirius B is the binary companion of Sirius A. As it is, the two systems exhibit a number of astonishing similarities: for instance, Mars and Sirius B are both about 205 times smaller than their ‘mothers’ (i.e. the Sun and Sirius A) - and both of the orbital eccentricities (“perigee to apogee”) of Mars and Sirius B can be shown to have a 1:7 ratio. This is hard to illustrate / demonstrate in writing, so you will have to find my website to view my graphics in Chapter 6 of my book.

The really great thing about Barnard’s Star having potentially multiple planets is that the star is very typical and close(to Earth) and therefore may infer that almost every solar system has planets. Planets are hard to discover unless they are close to the star or are very big. Assuming the other planets in the system turn out to be real, Barnard’s Star e is much closer to the habitable zone and there might be a Barnard’s Star ‘f’ after maintaining the discovery sequence, and ‘f’ would be in an even greater position for habitability, though the parent star’s flares could nix that possibility.

Why are astronomers so obsessed about tidally locked and devastating flares when we know so little about these planets yet? Tidally locked could just be Mercury-like kind of partial lock, which produces a 2:3 day:year cycle, which is weird but actually allows for seasonality and heat flow and thus potentially for easier life-bringng scenarios, they don't have to be "eyeball planets" necessarily. Flares are deflected by sufficiently strong magnetospheres and atmospheres are replenished depending on conditions, an extreme case is Venus, which has a weak magnetosphere yet has a massive atmosphere, excessive even. So let's go out and find what actually sits there and end speculation until that is acomplished. Less talk, more action.

I suspect the inner planets of Barnard's Star would be gravity locked, so even though they may too hot and have little atmosphere, there would be a strip of land in permanent twilight where the temperature is always good for humans. Any habitat built there would need to manage its atmosphere, but wouldn't have to deal with extreme temperatures - a considerable energy savings.

I saw this like 10 hours ago and I thought this was SO COOL :3

[@goatkiller666]

Now I need to re-read Flight of the Dragonfly, by Robert L. Forward. He was part of the “use actual science” crew. Asimov, for example. Started with a light sail to get it going enough that the Bussard Ram-Jet could get hydrogen fast enough to be meaningful. Even then, it’s several years in flight. Instead of cryo-sleep, the crew were taking a drug that stopped aging. But also left them thinking at a 1st grade level. So the AI took care of the crew. They find that there was a pair of planets orbiting each other, and then the CoG orbited the star. One planet was entirely populated by sentient blobs. Any two or three of them could merge a pseudopod in the center. When they then all sever their bonds to it, a new being is formed, with the accumulated memories of their parent. When something, somewhere else brought the two planets close enough (they already shared an atmosphere), and since the first planet was all ocean, this second was desiccated. Bur when the two were close enough, instead of the water bulging toward the other planet, there was a geyser that crossed the halfway point, then would fall onto the dry world. Be evaporated, and fall back to the dry world. I love how he invented his own supraliminal ideas, but also stuff we’ve thought about, solar sails, ramjets, how to send a ship somewhere far enough, without the ethical problems of expecting the kids and grandkids to do a mission they were never given a chance to volunteer for. I was in middle school, so forgive me for any gaps. I don’t remember what the antagonist was, or they figure the planets are close to disintegrating, so now we’re saving the goo people. It starts a little slow, so it can exposition all the high science going on. When I was in middle school, I was pretty interested in what we could currently draw. So I enjoyed the science deep dive. Others may not.

[@geekyoyd]

I got all excited then at the end you said the surface temperature is likely 125°C, well, if we go there, we won't need to plug in the kettle!

[@alanklm]

1:55 how is it that not all out of top-5 closest starts to Earth have names???

[@AnyOtherNamePlease]

The 'WISE' objects are substellar objects called brown dwarfs discovered relatively recently in the 2010s so they don't have more traditional names.

[@danieldesp0ta995]

man there should be a space telescope dedicated to only examine the first 100 light years diameters around the solar system to survey all stars for planets and other features.

[@andrewbreding593]

They thought pluto would be boring sterile, dead. We really haven't b investigated 😳😲 could be so many amazing things. We don't know what chemistry looks like in that environment. Maybe there's titan lurking out there. Absorbing lots of strange stellar chemistry. Could be a very dynamic system whatever it is. It would tell us so much more than finding earth 🌎 like system without 🌎

[@owenwilson25]

And, if roughly correct would be an ideal stepping stone for trans-stellar expansion. Ideally holding one or more airless or near-airless orbs with, say 0.2 to 0.6g and sufficient solar radiation to power a robotic construction base. After a few years, such planets could host a couple of safe subterranean habitat & fuel stations for passing human travellers. The only thing the robots would build on the surface, apart from power collectors, would be a couple of landing pads and an observatory or two that would provide extra data for transmission back to Earth.

[@Altar-Ego]

I’m excited to use these discovery techniques to find planets in ways other than transits. Could this method be used to find earth sized planets around stable sun-like stars?

[@kenyonmoon3272]

You know how some countries have a flag up or down to indicate whether the monarch is in residence? I feel like we need that, but for Barnard's Star. Flag is up? It has a planet this week. Flag down? It doesn't, at least not this month. And so on.

[@lethargogpeterson4083]

Nice. Maybe we can do something similar for how aquatic Spinosaurus was, or whatever it is they keep disagreeing about.

[@LuisAldamiz]

Never heard of that and I live in a monarchy (iSPain). There is a Spanish expression though: "estar en Babia" ("to be in Babia") which means colloquially that one is absent-minded, not paying attention and originally referred to the monarch being on vacation in a remote mountain valley by that name. No flags were downturned however, that would be disrespectful to flags.

[@danoblue]

So far, it seems that red dwarf stars may have lots of terrestrial planets, but what with the flares and tidal locking, there may be no such thing as a habitable zone for them. Interesting video, we are learning a lot in recent years about the myriad types of solar systems possible in our galaxy, not to mention the universe.

[@bonysminiatures3123]

i don't buy the flares and tidal locking they got it worng

[@KG-vn8ou]

Not sure why this is so exciting. There are plenty of planets that have been found and for one reason or another inhabitable! Just because this is close doesn’t make it any more do.

[@vensroofcat6415]

It would take mere 600 years to go there in a very optimistic scenario and 60 years in a miracle scenario. Also on a sidenote universe has nearly infinite amount of planets.

[@oberonpanopticon]

“Nearly infinite” is an interesting concept!

[@ThuThu-jz6xu]

The optimistic scenario is 10,000 years.

[@vensroofcat6415]

@@ThuThu-jz6xu that's why I called it very optimistic. We could eventually master 1% of the speed of light. Maybe in a few hundred years. It's more like an engineering problem. While for 10% of the speed of light even the physics start to have relativistic headaches.

[@vensroofcat6415]

@@oberonpanopticon as is infinite. Frankly we don't know. The idea is there are few trillion galaxies with some few hundred billion stars each in the visible universe. But we may be off by a lot.

[@king_dot]

Barnard’s Star had a nice planet in Hyperion would be cool if there’s actually a habitable planet there

[@PaulZyCZ]

Pity that laser array isn't being built yet in some desert, this would be great candidate to check close up with a swarm of micro-probes (formerly known as Breakthrough Starshot).

[@jameselliott216]

Suuuuper super close! Six light years. 🤔 Let's see. 25,000 mph • 6 LYs. . . Get there in six years, if we were traveling at light speed. Yayyy! 🤩

[@askani21]

You have a beautiful brain 😊

[@anthonydolio8118]

Interesting. Thanks.

[@troedsangberg]

"It just so happens that many red dwarfs turn out to be this, they're just a little bit too active for any life to survive on the surface" *surprised Pikachu face* aahhh! the surface of the _planets_ ... :D

[@3mpt7]

8:00 Great. I was wrong. Mental note: small Star.

[@joshuapatrick682]

That’s one that’s not causally disconnected, but there isn’t much.

[@ConcealedCourier]

Anton: "Is is Bernard..? Barnard?.." Janet Yellen: "Actually, it's B'nard."

[@WaterShowsProd]

It's written in IPA on that screen shot he's using. The first vowel is elongated, the second is a schwa.

[@ScottaHemi440]

that's cool! my old webcomic is now retroactively correct xD that's fun

[@tommyrjensen]

Anton, the pronunciation of Barnard's name is literally transcribed phonetically next to it on the Wikipedia page. Admittedly IPA is tougher to learn than русский or 한글. But once you master it, your viewers will have to consider you a very clever person.

[@MacarthurLouissaint-rz7tl]

Hey buddy can you do a video on FTL communication??

[@carlo70no]

It would be very short: that’s impossible. As far as we know now…

[@kalrandom7387]

Don't you love how no matter what we have to be special

[@susanm9124]

Wow! Cool.

[@MrTommyboy68]

I remember discussing Barnard's Star in elementary school science class (back in the dark ages).

[@100percentSNAFU]

Back in the good old days when Pluto was still the 9th planet!

[@rupertansell4662]

Pronunciation sounds fine to me. I’ve heard other astronomers call it Bar-nards Star…Brian Cox being one!

[@steverambo-rx7]

id like to think that, rightnow, a barnard star terrestrial planet dweller is watching their own barnard star anton giving exciting news of finding a "super-earth" orbiting in the habitable zone of a yellow dwarf six light years away

[@dougsinthailand7176]

I had high hopes for ESPRESSO!
